The design speed is a tool used to determine geometric features of a new road or street during road design . Contrary to the word's implication, the design speed of the road or street is not necessarily its vehicle speed limit or maximum safe speed; that can be higher or lower.
133-607: The Jackie Robinson Parkway (originally the Interboro Parkway ) is a 4.95-mile (7.97 km) controlled-access parkway in the New York City boroughs of Brooklyn and Queens . The western terminus of the parkway is at Jamaica Avenue in the Brooklyn neighborhood of East New York . It runs through Highland Park, along the north side of Ridgewood Reservoir , and through Forest Park . The eastern terminus
266-601: A dual highway ) in 1932 between Cologne and Bonn . It then rapidly constructed the first nationwide system of such roads. The first North American freeways (known as parkways) opened in the New York City area in the 1920s. Britain, heavily influenced by the railways, did not build its first motorway , the Preston By-pass ( M6 ), until 1958. Most technologically advanced nations feature an extensive network of freeways or motorways to provide high-capacity urban travel, or high-speed rural travel, or both. Many have
399-466: A median separates the opposite directions of traffic. This strip may be as simple as a grassy area, or may include a crash barrier such as a " Jersey barrier " or an "Ontario Tall Wall" to prevent head-on collisions . On some freeways, the two carriageways are built on different alignments; this may be done to make use of available corridors in a mountainous area or to provide narrower corridors through dense urban areas . Control of access relates to
532-560: A 18-foot-wide (5.5 m) median. City officials submitted a revised agreement on the proposed disinterments of bodies to Mount Carmel and Cypress Hills cemeteries' officials the next month. After cemetery officials agreed to the changes, the Board of Estimate approved final plans in June 1930, and a state judge authorized the disinterment of corpses within the cemeteries. The Brooklyn Chamber of Commerce requested that Mayor Jimmy Walker expedite
665-561: A class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention , the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals , intersections or property access . They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses . Entrances and exits to
798-707: A cloverleaf and trumpet interchange when it opened in 1937, and until the Second World War , boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since gone on to become the busiest highway in the world. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have
931-485: A committee of three men to determine what was needed for construction to begin, and the Queens Chamber of Commerce endorsed the parkway's construction. The Board of Estimate approved plans for the parkway that July; it also prepared a report on the parkway, which took more than a year to complete. After the parkway's route was approved, Queens's park department began growing 15,000 trees that were to be planted along
1064-620: A freeway, specialized pedestrian footbridges or tunnels may also be provided. These structures enable pedestrians and cyclists to cross the freeway at that point without a detour to the nearest road crossing. Access to freeways is typically provided only at grade-separated interchanges , though lower-standard right-in/right-out (left-in/left-out in countries that drive on the left) access can be used for direct connections to side roads. In many cases, sophisticated interchanges allow for smooth, uninterrupted transitions between intersecting freeways and busy arterial roads . However, sometimes it
1197-607: A further extension as far east as Dry Harbor Road and then toward Hoffman Boulevard (now Queens Boulevard ). An extension of Eastern Parkway following a similar route was suggested in 1899 by the Queens County Topographical Bureau, the extension running through Cypress Hills Cemetery and Forest Park to Dry Harbor Road. By 1901, Brooklyn surveyor Noyes F. Palmer had proposed extending Eastern Parkway another 2 miles (3.2 km) eastward into Forest Park. The same year, state legislators proposed amending
1330-581: A hill in Forest Park, infilled a hollow, and built the road atop the hollow. The same month, the city government awarded a contract for the construction of a pumping plant on the Interboro Parkway to prevent the road from flooding. By March, the temporary road was nearly complete. In addition, the Queens borough president's office had solicited bids for the construction of concrete barriers along
1463-530: A jersey with the number 42. Twenty-five signs were installed, replacing the old white-on-green signs. Controlled-access highway A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway , motorway , and expressway . Other similar terms include throughway or thruway and parkway . Some of these may be limited-access highways , although this term can also refer to

That May, the Board of Estimate approved the acquisition of land for the parkway after Long Island State Park Commission (LISPC) chairman Robert Moses asked the board to reconsider the plans. As part of the board's approval, the LISPC agreed to hire only contractors from New York state, and it had to employ laborers from the city. The Board of Estimate also modified the parkway's funding breakdown so that
1729-434: A larger number of guide signs than other roads, and the signs themselves are physically larger. Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on
1862-499: A legal status which limits the types of vehicles that can use a highway, as well as a road design that limits the points at which they can access it. Major arterial roads will often have partial access control , meaning that side roads will intersect the main road at grade, instead of using interchanges, but driveways may not connect directly to the main road, and drivers must use intersecting roads to access adjacent land. At arterial junctions with relatively quiet side roads, traffic
1995-512: A lower inferred design speed is neither effective nor good engineering practice." To be safe, the street must communicate the real level of risk to the driver. In other words, the driver must feel discomfort driving in a manner that is unsafe. – Charles Marohn (2021) The concept of design speed is evolving. The definition in the 1994 edition of the AASHTO Green Book, was "the maximum safe speed that can be maintained over
2128-527: A milepost system but does not use milepost markers. In Europe and some other countries, motorways typically have similar characteristics such as: Two-lane freeways , often undivided, are sometimes built when traffic volumes are low or right-of-way is limited; they may be designed for easy conversion to one side of a four-lane freeway. (For example, most of the Bert T. Combs Mountain Parkway in eastern Kentucky
2261-447: A motorway is understood as a public road with dual carriageways and at least two lanes each way. All entrances and exits are signposted and all interchanges are grade separated. Central barrier or median present throughout the road. No crossing is permitted, while stopping is permitted only in an emergency. Restricted access to motor vehicles, prohibited to pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The minimum speed
2394-777: A national-level or even international-level (e.g. European E route ) system of route numbering . There are several international standards that give some definitions of words such as motorways, but there is no formal definition of the English language words such as freeway , motorway , and expressway , or of the equivalent words in other languages such as autoroute , Autobahn , autostrada , autocesta, autoput , that are accepted worldwide—in most cases these words are defined by local statute or design standards or regional international treaties. Descriptions that are widely used include: One green or blue symbol (like [REDACTED] ) appears at motorway entry in countries that follow
2527-600: A number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type of road, etc. In some jurisdictions feeder/distributor lanes are common, especially for cloverleaf interchanges ; in others, such as the United Kingdom, where the roundabout interchange is common, feeder/distributor lanes are seldom seen. Motorways in Europe typically differ between exits and junctions. An exit leads out of
2660-624: A park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of the Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then
2793-457: A private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by the federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in

#17327767725372926-609: A reduction in deaths in a range from 20% to 50% on those sections. Speed, in Europe, is considered to be one of the main contributory factors to collisions. Some countries, such as France and Switzerland, have achieved a death reduction by a better monitoring of speed. Tools used for monitoring speed might be an increase in traffic density; improved speed enforcement and stricter regulation leading to driver license withdrawal; safety cameras; penalty point; and higher fines. Some other countries use automatic time-over-distance cameras (also known as section controls ) to manage speed. Fatigue
3059-610: A report on the parkway within one year. Tuttle recommended that 45% of the cost be covered by New York City, 35% by Brooklyn, 15% by Queens, and 5% by local residents. Amid continued opposition from religious groups, the Board of Estimate approved a revised plan for the parkway in May 1926, which would relocate 432 graves in Mount Carmel and Cypress Hills cemeteries. Tuttle sent the revised plan to Cypress Hills Cemetery's trustees for review that November. The trustees agreed to cede land for
3192-475: A road's design speed is sometimes used to determine an initial speed limit, it is an imperfect measure of the maximum speed at which a motor vehicle can be operated for reasons including: Recognizing the limitations on the use of the design speed for speed limit determination, "operating speeds and even posted speed limits can be higher than design speeds without necessarily compromising safety" and "arbitrarily setting lower speed limits at point locations due to
3325-480: A roadway." This reflects the fact that meeting a minimum design speed is not enough to ensure a safe roadway. Recently, the concept of design consistency has been used instead of minimum design speeds. This attempts to connect driver's expectations about the roadway with the roadway design. It uses driver behavior models to predict vehicle speeds on highway segments, and compares the predicted speed on adjacent segments. Significant reductions in speed from one segment to
3458-541: A separate roadway or altogether eliminates it. In some parts of the world, notably parts of the US , frontage roads form an integral part of the freeway system. These parallel surface roads provide a transition between high-speed "through" traffic and local traffic. Frequent slip-ramps provide access between the freeway and the frontage road, which in turn provides direct access to local roads and businesses. Except on some two-lane freeways (and very rarely on wider freeways),
3591-510: A similar system of express and local lanes for a maximum width of 21 lanes on a 2-mile (3.2 km) segment between Interstate 805 and California State Route 56 . In Mississauga , Ontario, Highway 401 uses collector-express lanes for a total of 18 lanes through its intersection with Highway 403 / Highway 410 and Highway 427 . These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes , either as
3724-411: A special restriction on the innermost lane or a separate roadway, to encourage carpooling . These HOV lanes , or roadways open to all traffic, can be reversible lanes , providing more capacity in the direction of heavy traffic, and reversing direction before traffic switches. Sometimes a collector/distributor road , a shorter version of a local lane, shifts weaving between closely spaced interchanges to
3857-422: A specified section of highway when conditions are so favorable that the design features of the highway govern. The assumed design speed should be a logical one with respect to the topography, the adjacent land use, and the functional classification of highway." Most US states used this definition. In 2004, the first sentence was changed to "a selected speed used to determine the various geometric design features of
3990-479: A supermajority of the cemetery's trustees and lot owners supported the project. This effectively banned any further extension of Eastern Parkway through the Cemetery Belt to Forest Park. Proponents of Eastern Parkway's extension continued to advocate their case. In 1906, a New York State Assembly member from Queens introduced a bill, which would allow a parkway to be built through Cypress Hills Cemetery with

4256-552: Is considered as a risk factor more specific to monotonous roads such as motorways, although such data are not monitored/recorded in many countries. According to Vinci Autoroutes , one third of accidents in French motorways are due to sleepy driving. Design speed Choosing a design speed means finding a balance between several interests which compete for priority, such as high vehicle speeds to allow drivers to travel to their destinations quickly versus low vehicle speeds for
4389-735: Is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater interference with traffic are still preferred in North America. There may be occasional interchanges with other major arterial roads. Examples include US 23 between SR 15 's eastern terminus and Delaware, Ohio , along with SR 15 between its eastern terminus and I-75 , US 30 , SR 29 / US 33 , and US 35 in western and central Ohio. This type of road
4522-655: Is necessary to exit onto a surface road to transfer from one freeway to another. One example in the United States (notorious for the resulting congestion) is the connection from Interstate 70 to the Pennsylvania Turnpike ( Interstate 70 and Interstate 76 ) through the town of Breezewood, Pennsylvania . Speed limits are generally higher on freeways and are occasionally nonexistent (as on much of Germany's Autobahn network). Because higher speeds reduce decision time, freeways are usually equipped with
4655-450: Is not lower than 50 km/h [31 mph] and the maximum speed is not higher than 130 km/h [81 mph] (except Germany where no speed limit is defined). Motorways are designed to carry heavy traffic at high speed with the lowest possible number of accidents. They are also designed to collect long-distance traffic from other roads, so that conflicts between long-distance traffic and local traffic are avoided. According to
4788-431: Is provided with separate carriageways for the two directions of traffic). Principal arterials may cross through urban areas, serving suburban movements. The traffic is characterized by high speeds and full or partial access control (interchanges or junctions controlled by traffic lights). Other roads leading to a principal arterial are connected to it through side collector roads. In this view, CARE's definition stands that
4921-407: Is sometimes called an expressway . Freeways are usually limited to motor vehicles of a minimum power or weight; signs may prohibit cyclists , pedestrians and equestrians and impose a minimum speed. It is possible for non-motorized traffic to use facilities within the same right-of-way, such as sidewalks constructed along freeway-standard bridges and multi-use paths next to freeways such as
5054-480: Is specially sign-posted as a motorway and is reserved for specific categories of road motor vehicles." Urban motorways are also included in this definition. However, the respective national definitions and the type of roads covered may present slight differences in different EU countries. The first version of modern controlled-access highways evolved during the first half of the 20th century. The Long Island Motor Parkway on Long Island , New York , opened in 1908 as
5187-545: Is the result of several changes, including infrastructure safety and road user behavior (speed or seat belt use), while other matters such as vehicle safety and mobility patterns have an impact that has not been quantified. Motorways are the safest roads by design. While accounting for more than one quarter of all kilometres driven, they contributed only 8% of the total number of European road deaths in 2006. Germany's Federal Highway Research Institute provided International Road Traffic and Accident Database (IRTAD) statistics for

5852-486: The Grand Central Parkway 's eastbound and westbound lanes, respectively. The parkway has several sharp curves throughout its route, particularly within the cemeteries. The curves exist because, at the time of the parkway's construction, planners wished to disturb as few graves as possible. As designed, the curves limited the design speed of the Interboro Parkway to 35 miles per hour (56 km/h). The curves are particularly hazardous; The New York Times wrote in 1997 that

A similar bill was introduced in the State Senate in 1907; it received less opposition than the previous bills for the road had. The legislation for the Cemetery Belt road was finally passed in 1908, permitting the construction of a 150-foot-wide (46 m) road through the cemeteries. The bill also authorized the Board of Estimate to survey

Though nearby property owners supported the parkway's extension, the cemeteries' owners opposed it. Opponents said the roadway would displace about 300 graves and that it would divide the cemeteries, and the Cypress Hills Cemetery Corporation later claimed that
6384-867: The Suncoast Trail along the Suncoast Parkway in Florida . In some US jurisdictions, especially where freeways replace existing roads, non-motorized access on freeways is permitted. Different states of the United States have different laws. Cycling on freeways in Arizona may be prohibited only where there is an alternative route judged equal or better for cycling. Wyoming , the second least densely populated state, allows cycling on all freeways. Oregon allows bicycles except on specific urban freeways in Portland and Medford . In countries such as
6517-538: The United Kingdom new motorways require an Act of Parliament to ensure restricted right of way. Since upgrading an existing road (the "King's Highway") to a full motorway will result in extinguishing the right of access of certain groups such as pedestrians, cyclists and slow-moving traffic, many controlled access roads are not full motorways. In some cases motorways are linked by short stretches of road where alternative rights of way are not practicable such as

6783-838: The safety of people outside the vehicle (such as pedestrians and cyclists ), or quick movement of peak traffic ( traffic engineering ) versus maximising the economic development potential of the street ( urban planning ). The design speed chosen for a high-speed roadway is a major factor in choosing superelevation rates and radii of curves , sight distance , and the lengths of crest and sag vertical curves . Roads with higher design speeds require wider lanes , sweeping curves, wider recovery areas, broader clear zones , steeper curve banking, longer sight distances, and more gentle hill crests and valleys. Roads and streets with lower design speeds require narrower lanes, sharper/tighter curves, smaller or no clear zones, less banking, less sight distance, and sharper hill crests and valleys. While

California , Ohio and Nevada use postmile systems in which the markers indicate mileage through the state's individual counties. However, Nevada and Ohio also use the standard milepost system concurrently with their respective postmile systems. California numbers its exits off its freeways according to

Sometimes they deplete farmland, but other methods have been developed for economic, social and even environmental reasons. Full freeways are sometimes made by converting at-grade expressways or by replacing at-grade intersections with overpasses; however, in

A formal dedication ceremony for the parkway took place on November 12, 1935, at the Highland Boulevard overpass; a special exhibit about the parkway was displayed at the Brooklyn Automobile Show to celebrate the opening. Issues with the parkway designed plagued its usefulness, as declared by the New York City Planning Department in 1941. One issue
7448-514: The Interboro Parkway and two others in New York state were modified in July 1932 because they had gone over budget. That December, the Board of Estimate's chief engineer published a report estimating that it would cost $ 2 million to complete the Interboro Parkway, though the board deferred a decision on the report following opposition from Manhattan's and Staten Island's borough presidents. At the time,

By then, the Cypress Hills Cemetery's trustees were selling burial plots right next to the path of the proposed parkway. Little progress on the Interborough Parkway's construction had occurred by 1921, in part because Mount Carmel Cemetery burial-plot owners opposed constructing the parkway through that cemetery. Rabbis also opposed
7980-409: The US, any at-grade intersection that ends a freeway often remains an at-grade intersection. Often, when there is a two-lane undivided freeway or expressway, it is converted by constructing a parallel twin corridor, and leaving a median between the two travel directions. The median-side travel lane of the old two-way corridor becomes a passing lane. Other techniques involve building a new carriageway on

As opposed to the routing approved in 1914, which would have included a gradual curve to the northeast of Cypress Hills Street, this proposal would introduce a sharp curve about 450 feet (140 m) east of Cypress Hills Street. In May 1924, Governor Al Smith signed a bill authorizing the city government to construct the parkway. The legislation required Tuttle to create

London Orbital or the M25 is a motorway surrounding London , but at the last River Thames crossing before its mouth, motorway rules do not apply. (At this crossing the London Orbital is labeled A282 instead.) A few of the more common types of junction are shown below: There are many differences between countries in their geography, economy, traffic growth, highway system size, degree of urbanization and motorization, etc.; all of which need to be taken into consideration when comparisons are made. According to some EU papers, safety progress on motorways

The state legislature passed a law the next month, allowing the Cemetery of the Evergreens to transfer ownership of land for the parkway's right-of-way. Though Governor Herbert H. Lehman signed the bill, the Board of Estimate initially failed to approve the acquisition of the land because Manhattan borough president Samuel Levy opposed it. In addition, Moses initially claimed that local streets could adequately handle traffic to and from
8911-445: The central section was nearly finished by October. The central section, costing $ 463,000, was mostly completed that December, five months ahead of schedule. However, the parkway remained closed because it was not paved and because its eastern terminus was a dead end. A temporary 250-foot-long (76 m) road was constructed to connect the central section's eastern terminus with Forest Park Drive starting in January 1932. Workers leveled
9044-476: The city government acquired title to the land. After the Board of Estimate approved the parkway's completion through Forest Park, 400 people were hired to clear the right-of-way, and two beer gardens there had to be demolished for the parkway. A 200-year-old homestead at the parkway's eastern end also had to be demolished. In June 1933, the board voted to approve the damage maps for the parkway's eastern section. The board also voted to acquire two strips of land along

The section between Cypress Hills Street and Forest Park was also delayed while the city government and Cypress Hills Cemetery's trustees resolved some legal issues over the routing. The Board of Estimate approved $ 774,000 for preliminary work along the parkway's right-of-way in October 1928, and the Queens park commissioner requested $ 289,000 for
9709-415: The dangerous 3,700 feet (1,100 m)-long curved section of the roadway between Cypress Hills Street and Forest Park Drive. Work was expected to begin in summer 1973. The project would realign the roadway where possible to ease S-curves, resurface pavement, install water-filled plastic buffers at accident-prone locations, create spaces along the road for disabled vehicles, and replace 16-inch high barriers in
9842-503: The dangerous westbound exit to Cypress Hills Street to lessen the impact of crashes, and four parking spots would be completed along the roadway with police telephones for stranded drivers. State and city officials estimated it would cost over $ 70 million to make the entire parkway safe. Part of the original parkway contract included the construction of a pair of service stations just west of exit 6 (Metropolitan Avenue) in Forest Park. The stone-faced gas stations, which were located along
9975-517: The early 1920s in response to the rapidly increasing use of the automobile , the demand for faster movement between cities and as a consequence of improvements in paving processes, techniques and materials. These original high-speed roads were referred to as " dual highways " and have been modernized and are still in use today. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"),
10108-437: The eastbound and westbound lanes of the parkway, were torn down in the late 1970s. The New York State Department of Transportation began reconstructing parts of the parkway in 1987. Ramps along the parkway were rebuilt, converting the junction with Metropolitan Avenue at Exit 6 from a tight cloverleaf interchange to a four-ramp diamond interchange. The road was rebuilt as well, installing a concrete median and new lighting along
10241-485: The first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the A8 and A9 motorways, was devised by Piero Puricelli and was inaugurated in 1924. This motorway, called autostrada , contained only one lane in each direction and no interchanges. The Bronx River Parkway was the first road in North America to utilize a median strip to separate the opposing lanes, to be constructed through
10374-412: The first half of the 20th century. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. Italy opened its first autostrada in 1924, A8 , connecting Milan to Varese . Germany began to build its first controlled-access autobahn without speed limits (30 kilometres [19 mi] on what is now A555 , then referred to as
10507-504: The highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials and collector roads . On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, while increasing traffic capacity and speed. Controlled-access highways evolved during
10640-490: The highway. Exit 3, Cypress Hills Street, leads to Cypress Hills Cemetery, where Jackie Robinson is buried. At exit 4, Forest Park Drive, the parkway enters Forest Park in Queens. Exit 5 is Myrtle Avenue and Woodhaven Boulevard . At exit 6, Metropolitan Avenue, Union Turnpike straddles the parkway, but there is no access to or from Union Turnpike. The parkway and Union Turnpike then exit Forest Park and go under Queens Boulevard ( NY 25 ) and above
10773-408: The intersection of Bushwick, Pennsylvania, and Jamaica avenues, where the parkway's western terminus was to be located, in June 1934. The Board of Estimate approved plans for the parkway's westward extension that month. The Interboro Parkway was scheduled to open to traffic on November 1, 1934. The Interboro Parkway opened to traffic in July 1935. However, it remained unfinished until the completion of
10906-508: The land the next month, and officials published notices about the condemnation proceedings in The City Record . City officials were supposed to have obtained title to the right-of-way no later than September 15, and the city government acquired the land that month. However, the start of work was subsequently delayed to mid-1929 while the city determined how to route the parkway through the cemeteries, as well as miscommunications about
11039-614: The legislation later that month. However, some street maps, such as the New York City Taxi and Limousine Commission 's official map, bore the older name for several years. In early 2018, the New York City Department of Transportation installed new black-on-white route designation signs on the Jackie Robinson Parkway as part of a program to replace route-designation signs across New York City's parkways. The signs contain an image of Robinson at bat, wearing
11172-469: The mayor of Cologne . The German Autobahn became the first nationwide highway system. In Canada , the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured
11305-539: The median of the roadway with three-foot tall concrete barriers. Engineers would also look into the feasibility of widening the roadway, though the retaining walls for cemeteries abutting both sides of the S-curve section posed a challenge to doing so. The city was also in the process of applying for federal funds for an overall project to modernize the roadway along its entire length, which was expected to cost between $ 60 million and $ 75 million. Additional safety hazards on
11438-400: The motorway system, whilst a junction is a crossing between motorways or a split/merge of two motorways. The motorway rules end at exits, but not at junctions. However, on some bridges, motorways, without changing appearance, temporarily end between the two exits closest to the bridge (or tunnel), and continue as dual carriageways . This is in order to give slower vehicles a possibility to use
11571-462: The next are flagged as locations where drivers may end up driving too fast for road conditions. A major shift in philosophy is also taking place regarding design speed of urban and suburban streets. Highway engineers would measure the prevailing speed on a road, round up to the next multiple of 5 miles per hour (8.0 km/h), and design the road for that speed, assuming that it would be safe. Recent research and design practices have focused on using
11704-442: The next month. In addition to the construction of bridges, the project required relocating utilities, rerouting Union Turnpike's eastbound lanes, and constructing a water-pumping station. Several houses along the right-of-way had to be cut back or even demolished entirely. During the parkway's construction, several landowners claimed that workers were damaging their lawns. Residents and merchants in central Queens also complained that
11837-439: The other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than 100 metres (330 ft)). An interchange or a junction is a highway layout that permits traffic from one controlled-access highway to access another and vice versa, whereas an access point is a highway layout where traffic from a distributor or local road can join a controlled-access highway. Some countries, such as
11970-421: The parkway between the 1900s and the 1920s, which failed due to a lack of funding and various disagreements over land acquisition. The parkway's route was finalized in 1930, and work on the central section through Mount Carmel and Cypress Hills cemeteries began in 1931. Construction on the rest of the parkway did not begin until 1933. Most of the parkway opened to traffic in July 1935, but the westernmost section
12103-421: The parkway has been nicknamed "Suicide Row", "Slaughter Parkway" and "Death Alley" throughout the years. A junction at the eastern end of the parkway was placed on the list of New York State's most dangerous roads in 2007, based on accident data from 2004–2006. Frederick Law Olmsted and Calvert Vaux , who designed Prospect Park , had suggested the construction of Eastern Parkway and Ocean Parkway in 1866;
12236-421: The parkway on the condition that work begin before January 1, 1928. Despite the Board of Estimate's claims that the project may delayed because of a lack of local interest, four civic groups asked the Board of Estimate to begin construction as soon as possible. Rabbis continued to oppose the project due to the disinterments, and Brooklyn's borough president James J. Byrne objected to the proposed cost breakdown for
12369-426: The parkway under Queens Boulevard, which measured 80 feet (24 m) wide and was built by New York City Subway contractors. The Queens borough president's office was to oversee the construction of the eastern section within Forest Park, which was to cost an estimated $ 500,000. An overpass and two pedestrian underpasses would be built, and Forest Park's golf course was to be reconfigured. Engineers also wanted to build
12502-513: The parkway was closed as work began on reconstruction of a 4,100 feet (1,200 m) section of the highway between Cypress Hills Street and Forest Park Drive, where at least ten people were killed and many more were injured in this section over the previous five years. The one-year $ 1.7 million project would install a reinforced center divider, smooth out asphalt, and bank the S-curves of the roadway. Water-filled plastic containers would be placed at
12635-410: The parkway's Forest Park section the following January. A proposed state law, which would have implemented a gas tax to pay for the parkway's construction, was unsuccessful. The city government approved plans for sewers on the right-of-way in March 1929, and Queens borough president George U. Harvey requested that July that the Board of Estimate authorize the grading of the parkway's right-of-way. At
12768-404: The parkway's construction because it would require moving hundreds of corpses from Mount Carmel and Cypress Hills cemeteries, including the bodies of many Jews, whose disinterment would violate Jewish tradition. As the presence of motor vehicles was increasing, by 1923, local civic associations were pressuring the government to build the road. The associations requested that the city government build
12901-407: The parkway's construction. The Welsh Brothers Construction Company submitted the lowest bid for grading the Interboro Parkway's right-of-way. Work on the parkway itself began April 6, 1931, after 365 corpses had been relocated. The first part of the parkway to be constructed was the central section through Cypress Hills and Mount Carmel cemeteries, which was the hardest to construct. By mid-1931, one of
13034-443: The parkway's construction. Work had still not started by October because the bodies had to be removed from the cemeteries before any work on the parkway could begin. Though the state government tentatively offered to pay for the Interboro Parkway's construction if the right-of-way was increased to 190 feet (58 m), the city government declined the offer, especially since it would have required further land condemnation. As mapped out,
13167-496: The parkway's eastern section, as the project could not receive federal and state funding if the city did not take title to the land. In addition, Queens officials asked the city government to repair streets that connected with the parkway, and workers subsequently repaved one of these streets, Cypress Avenue. To prevent congestion on Cypress Avenue, the Brooklyn–Manhattan Transit Corporation proposed replacing
13300-545: The parkway's eastern section; though Benninger claimed that the city had failed to approve the funding request for several months, Walker said he had not been aware of the request. There were also plans to widen and pave part of Union Turnpike to provide a direct connection between Interboro and Grand Central parkways, and the city was acquiring a 140-foot-wide (43 m) strip of land from Queens Boulevard to Austin Street for that purpose. The connector included an underpass carrying
13433-510: The parkway's extension in 1896. The Eastern Parkway Extension, along with Highland Boulevard, had been completed by 1897. What became Jackie Robinson Parkway originated from plans to extend Eastern Parkway even further. After the consolidation of the City of Greater New York in 1898, there were proposals to extend Eastern Parkway further east to Forest Park in Queens . Brooklyn officials suggested
13566-554: The parkway's western end was at Highland Park, while its eastern end was at Union Turnpike; a connection between Eastern and Interboro parkways was made via Bushwick Avenue and Highland Boulevard. City officials anticipated that the parkway would help relieve congestion on Queens Boulevard and Hillside Avenue in conjunction with the Grand Central Parkway , which was to run from the Interboro's eastern end toward Nassau County, New York . In March 1931, Harvey began reviewing bids for
13699-577: The parkway, and the New York Supreme Court had begun compensating burial-plot owners whose land had been seized for the parkway's construction. The central section was still unpaved by that June, and it remained unopened even in 1933. Meanwhile, the Board of Estimate allocated $ 27,000 for surveys and maps of the parkway's right-of-way in November 1931. The same month, Queens park commissioner Albert C. Benninger requested $ 288,000 to grade
13832-587: The parkway, and the Queens Chamber of Commerce appointed a special committee to oversee the parkway's construction. The parkway was to be constructed in three sections: the westernmost portion in Highland Park, the central portion next to Cypress Avenue and the Ridgewood Reservoir, and the eastern section through Cypress Hills and Mount Carmel cemeteries. The Board of Estimate also asked its Committee on Assessment to determine who should pay for
13965-520: The parkway, but this process had not been finalized by 1917. By then, the parkway's cost was estimated at $ 500,000. One proposal called for the cost to be divided evenly between the New York City, Brooklyn, and Queens governments. Another proposal called for the city to pay half the cost and the Brooklyn and Queens governments to split the other half; the Committee of Assessments recommended using this cost breakdown. Work still had not started by 1919, when
14098-450: The parkway. The Board of Estimate authorized the parkway's construction in February 1927. The next month, they convened to discuss the cost estimates for the parkway, which was projected to cost $ 3.5 million. The Board of Estimate voted to adopt the cost breakdown that Tuttle had proposed, and it recommended that land condemnation begin before the end of the year. In July 1927, New York Supreme Court justice James Church Cropsey authorized
14231-399: The parkway. The board finally agreed to buy the land in March 1934, over Levy's continued objections. The LISPC began receiving bids for the construction of a bridge above the parkway at Myrtle Avenue, as well as the replacement of a superintendent's house at Ridgewood Reservoir, in March 1934. Shortly afterward, State Supreme Court justice Charles C. Lockwood ruled that the city government
14364-510: The plans called for an additional 11 bridges and 5 pedestrian overpasses along the parkway. The project was further delayed by opposition from the city's controller. When John P. O'Brien was inaugurated as the city's new mayor at the beginning of 1933, civic groups asked him to approve the plans, but he also moved to delay the parkway's completion, citing a lack of money. Work on the Queens Boulevard underpass had also stalled due to
14497-407: The plans with the operators of Cypress Hills and Mount Carmel cemeteries, from which it planned to acquire land. Though Cypress Hills Cemetery's trustees were willing to sell their land for $ 1 per square foot ($ 11/m). more than what the city was willing to pay, Mount Carmel Cemetery's trustees were unwilling to sell their land at all. The city government agreed to acquire 11.2 acres (4.5 ha) from
14630-478: The project was disrupting businesses and causing hazardous conditions for pedestrians, prompting construction contractors to expedite the parkway's completion. Work on the eastern section was delayed in late 1933 and early 1934 due to snowy weather. Moses announced in December 1933 that the parkway was to be extended further west from Highland Boulevard to Bushwick Avenue. Under this plan, an additional mile of road
14763-477: The rate is higher than the risk on urban roads. Speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash. According to ETSC, German motorways without a speed limit, but with a 130 km/h (81 mph) speed recommendation, are 25% more deadly than motorways with a speed limit. Germany also introduced some 130 km/h (81 mph) speed limits on various motorway sections that were not limited. This generated
14896-403: The required funds for the extension, though city officials held informal meetings about the roadway. By 1913, the plans called for about 2 miles (3.2 km) of new roadway, and the parkway had been narrowed to 100 feet (30 m). The road would have split from Highland Boulevard, run to the north of Ridgewood Reservoir , then continued eastward to Union Turnpike . The city government discussed
15029-643: The rights of light , air and access to highways, but not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus, as originally conceived, a freeway is simply a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Freeways, by definition, have no at-grade intersections with other roads, railroads or multi-use trails . Therefore, no traffic signals are needed and through traffic on freeways does not normally need to stop at traffic signals. Some countries, such as
15162-437: The roadway included many small-radius curves, inadequate median separation barriers, and exits and entrances without acceleration or deceleration lanes. Simon-Eristoff also said that he wanted the roadway to be incorporated into either the federal highway or state arterial systems, which would require state legislation. This legislation was proposed and signed into law by Governor Malcolm Wilson in May 1973. On November 4, 1974,
15295-472: The route of the proposed Eastern Parkway extension, but work stopped due to a lack of money for construction. Plans to construct a road through the Cemetery Belt were revived in 1911. The New York Times wrote that the proposed road would "open up a most pleasant and easy way of getting to and from Queens by automobile by way of Brooklyn". At the time, very few streets connected southern Brooklyn and Queens. The New York City Board of Estimate failed to allocate
15428-489: The route's right-of-way . Supporters of the project said that the parkway's construction would not entail disturbing any graves at Cypress Hills Cemetery, since the Eastern Parkway extension would traverse the cemetery on three viaducts. Queens's deputy commissioner of public works, Alfred Denton, proposed extending the road as far east as Hoffman Boulevard without traveling through the Cemetery Belt. The city surveyed
15561-401: The route. Speed limits were decreased at the swerving curve at the Cypress Hills Cemetery and at the curve beneath the Queens Boulevard underpass, problem spots noted earlier in the 1941 report by the New York City Planning Department. The project cost $ 43.1 million and took place between 1989 and 1991. In April 1997, mayor Rudy Giuliani announced that the parkway would be renamed in honor of
15694-432: The side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas. When a third carriageway is added, sometimes it can shift a directional carriageway by 20–60 metres (50–200 ft) (or maybe more depending on land availability) as a way to retain private access on one side that favors over
15827-467: The streetcars on that avenue with buses. After the city had formally acquired the parkway's route, it formally began soliciting bids for the construction of bridges on the parkway. The first contract for the eastern section was awarded in August 1933, when contractors began constructing three bridges to carry local traffic across the Interboro Parkway. This contract had to be completed within two months but
15960-404: The three overpasses over the parkway's central section had been completed, having been built in one day, and grading of the parkway's central section was half-finished. The Brooklyn borough president's office had also received permission to begin grading the parkway's western section. Other aspects of the project were delayed by rainy weather and unusually muddy soil. Excavation and concrete work for
16093-472: The time, the board was still awaiting a final report from Tuttle. Another public hearing had to be hosted for the parkway after Tuttle determined that the work would cost $ 89,000 more than originally predicted. An overpass between the cemeteries had also been added to the plans, which required public review as well. In October 1929, the Board of Estimate approved the specifications for the parkway, which called for two 30-foot-wide (9.1 m) roadways, separated by
16226-487: The trustees of Cypress Hills Cemetery after the trustees opposed the legislation. When the bill was reintroduced in 1903, the Brooklyn Citizen wrote that the lands to be seized for the parkway were nearly empty; at the time, many local politicians, residents, and civic groups favored the bill. An opposing bill, passed in 1904, prohibited the construction of public roads through any cemetery in New York state unless
16359-519: The two cemeteries, and the cemeteries' presidents were ready to accept the plans for the parkway by late 1913. Cypress Hills Cemetery's trustees agreed to sell their land for $ 0.35 per square foot ($ 3.8/m). By February 1914, the New York City Board of Estimate was ready to consider plans for the parkway. At the time, the road was variously called the Cemetery Road, Interborough Parkway, or Eastern Parkway Extension. The Queens government appointed
16492-593: The two parkways extended east and south of Prospect Park, respectively. Eastern Parkway was completed in the mid-1870s and originally terminated at Ralph Avenue. In the early 1890s, Brooklyn officials proposed extending the parkway northeast to near Cemetery of the Evergreens , Highland Park , and the Ridgewood Reservoir along Brooklyn and Queens' Cemetery Belt . Eastern Parkway itself was extended as far as Bushwick Avenue, and another road called Highland Boulevard continued eastward from Bushwick Avenue to Highland Park. Governor Levi P. Morton signed legislation to authorize
16625-427: The western section near Ridgewood Reservoir by December 1931, but they had to wait for the city's water department to relocate water mains . By May 1932, there were plans to extend the parkway from Highland Boulevard to Bushwick Avenue. One option called for the parkway to extend southwest to Pennsylvania Avenue, while another option would bring the parkway in a more westerly direction toward Eastern Parkway. Plans for
16758-406: The year 2010, comparing overall fatality rates with motorway rates (regardless of traffic intensity): The German autobahn network illustrates the safety trade-offs of controlled access highways. The injury crash rate is very low on autobahns, while 22 people died per 1,000 injury crashes—although autobahns have a lower rate than the 29 deaths per 1,000 injury accidents on conventional rural roads,
16891-443: Was European route E4 from Gävle to Axmartavlan , Sweden. The high rate of crashes with severe personal injuries on that (and similar) roads did not cease until a median crash barrier was installed, transforming the fatal crashes into non-fatal crashes. Otherwise, freeways typically have at least two lanes in each direction; some busy ones can have as many as 16 or more lanes in total. In San Diego, California , Interstate 5 has
17024-399: Was delayed due to inclement weather. The Board of Estimate reviewed and approved contracts for three additional segments of the Interboro Parkway's eastern section, between Woodhaven Boulevard and Metropolitan Avenue, that September. By November, contracts for 11 bridges along the Interboro Parkway's eastern section were being awarded; further contracts for bridges along the parkway were awarded
17157-581: Was not completed until that September. Over the years, the Interboro Parkway gained a reputation for being dangerous because of its sharp turns and narrow lanes. The Interboro Parkway was renamed for Major League Baseball player Jackie Robinson in 1997. The Jackie Robinson Parkway starts at an intersection with Jamaica , Pennsylvania , and Bushwick avenues in the East New York neighborhood in Brooklyn . The westernmost four exits are located within
17290-491: Was presumed to serve as a service road for the extended parkway. Construction cost was estimated at $ 30 million and scheduled for completion in 1976. However, the extension was cancelled in the late 1960s. On September 12, 1972, Transportation Administrator Constantine Sidamon-Eristoff announced that the New York City Board of Estimate approved a contract for the design of a $ 1,472,000 project to improve safety on
17423-449: Was the presence of "bad curves" at two sections of the parkway. These curves, as viewed by the department, were a "serious hazard" to drivers, but rectifying the problem would prove difficult due to the parkway's location through cemeteries. Furthermore, the department criticized a lack of highway connections at the parkway's western terminus in Brooklyn. The department suggested that the proposed Cross Brooklyn Express Highway would connect to
17556-464: Was to be constructed, requiring the condemnation of 7.5 acres (3.0 ha) in the Cemetery of the Evergreens . Because the parkway would replace an existing roadway, this tract of land did not require disinterments, as had been the case with Cypress Hills and Mount Carmel cemeteries. State engineers rejected a proposal to construct a tunnel under the parkway, which would have avoided the need to disturb
17689-558: Was to give $ 1,756,599 in compensation to 170 landowners whose land had been seized for the parkway. This was less than half the $ 4 million that the landowners had originally requested. The city government also issued corporate stock to pay for the acquisition of land for the Interboro Parkway. Progress on the rest of the parkway was stalled by inclement weather, but several contracts for the eastern section were being completed by mid-1934, including bridges at Metropolitan Avenue and Woodhaven Boulevard. Moses presented plans for an entrance plaza at
