109-484: State Road 878 ( SR 878 ), named the Snapper Creek Expressway , is a 2.7-mile (4.3 km) east–west controlled-access toll road south of Miami , Florida . The expressway is named for the nearby Snapper Creek which runs parallel to SR 878. It acts as a spur route of SR 874 (Don Shula Expressway), providing access to U.S. Route 1 (US 1) near South Miami and local access to
218-663: 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
327-466: 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
436-628: A "Sheriff's Office". Instead, the county's law enforcement agency is known as the Miami-Dade Police Department, and its leader is known as the Metropolitan Sheriff and Director of the Miami-Dade Police Department; Nonetheless, Miami-Dade Police badges bear the inscription, "Deputy Sheriff, Sheriff's Office, Dade County, Fla." Miami-Dade County has voted for the Democratic Party candidate in most of

As of 2022, Miami-Dade County has a gross domestic product of $ 184.5 billion, making the county's GDP the largest for any county in the State of Florida and the 14th-largest for the nation's 3,033 counties. The county is home to the Port of Miami on Biscayne Bay , the world's largest passenger port with
654-561: 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
763-707: 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
872-544: A four-lane-wide expressway through residential neighborhoods for the remainder of its length, generally lying 0.5 miles (0.80 km) north of Kendall Drive. After approximately 0.4 miles (0.64 km), the Snapper Creek Expressway passes through the 87th Avenue toll gantry . It then meets Galloway Road (SR 973) shortly afterwards with a diamond interchange . The expressway then enters Glenvar Heights once it crosses SR 973 and remains in that district for
981-620: 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
1090-405: A household in the county was $ 43,605, and the median income for a family was $ 50,065. Males had a median income of $ 35,096 versus $ 29,980 for females. The per capita income for the county was $ 22,957. About 13.8% of families and 17.2% of the population were below the poverty line , including 22.0% of those under age 18 and 22.1% of those aged 65 or over. In 2010, 51.1% of the county's population
1199-434: 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
SECTION 10
#17327809429891308-499: 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
1417-527: 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
1526-447: 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
1635-777: 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
1744-600: 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
1853-624: 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
1962-457: 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
2071-609: 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
2180-541: 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),
2289-510: 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

Originally, the county was set to be named " Pinckney County ", after Thomas Pinckney , a statesman and diplomat from South Carolina who drafted the Treaty of San Lorenzo . The county's credited father, Richard Fitzpatrick, preferred this name as he was from South Carolina himself; however, when news reached Tallahassee of
2507-411: 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
2616-459: A variant of Tequesta , which was Miami's first recorded name. It is unknown whether he came ashore or made contact with the natives. Pedro Menéndez de Avilés and his men made the first recorded landing when they visited the Tequesta settlement in 1566 while looking for Avilés' missing son, shipwrecked a year earlier. Spanish soldiers led by Father Francisco Villarreal built a Jesuit mission at

Each additional axle on a vehicle attracts an extra $ 0.25 via SunPass or $ 0.50 via toll-by-plate for each toll gantry passed. Planning by Dade County for a road named the "Snapper Creek Expressway" was underway as early as 1958, with a final completion date set as late as 1975. Funding for SR 878's construction was made available in 1971 by

In 2005 the Jewish population of the county has decreased but stabilized at about 121,000 with a high percentage of retired and elderly persons (but less than in Broward and Palm Beach counties). There are more than 60 congregations, 34 Jewish educational institutions, and three Jewish community centers. The highest percentage and increase in Jewish population
3161-458: 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. Miami-Dade County, Florida Miami-Dade County ( / m aɪ ˈ æ m i ˈ d eɪ d / ) is a county located in the southeastern part of
3270-735: 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

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

Other roads leading to a principal arterial are connected to it through side collector roads. In this view, CARE's definition stands that
4251-407: 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

Florida's Constitution provides for five elected officials to oversee executive and administrative functions for each county (called "Constitutional Officers"): Sheriff , Property Appraiser, Supervisor of Elections, Tax Collector, and Clerk of the Circuit Court (also functions as Comptroller). However, the Constitution allows voters in home-rule counties (including Miami-Dade) to abolish
8611-517: 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"),
8720-618: The early 19th century. People came from the Bahamas to South Florida and the Keys to hunt for treasure from the ships that ran aground on the treacherous Great Florida Reef . Some accepted Spanish land offers along the Miami River. At about the same time, the Seminole Indians arrived, along with a group of runaway slaves. The area was affected by the Second Seminole War , during which Major William S. Harney led several raids against

SR 878's western terminus is integrated into the Don Shula Expressway's interchange with SR 94 (Kendall Drive) across the boundary of the Kendall and Sunset districts . Motorists entering the Don Shula Expressway northbound from Kendall Drive are given
8938-424: The first between the Don Shula Expressway and Galloway Road, and the second between Galloway Road and Southwest 72nd Avenue. The relationship between the tolling points and interchanges along SR 878 and SR 874 is that all motorists are charged at least one toll for using the road; there are no "free sections". As of July 1, 2013, the cost for a two-axle vehicle to travel the entire length of the Snapper Creek Expressway
9047-485: 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.

9810-400: 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
9919-631: The mouth of the Miami River a year later but it was short-lived. After the Spaniards left, the Tequesta Indians were left to fend themselves from European-introduced diseases like smallpox .

10791-477: 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
10900-552: The rest of its duration. Just before passing over the Palmetto Expressway (SR 826) without an interchange (approximately 1 mile (1.6 km) east of Galloway Road), SR 878 meets its second and final toll gantry.

11009-643: 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
11118-543: The road was left partially completed; however, $ 8 million in federal emergency funds was directed to completing the expressway in late 1977. The Snapper Creek Expressway, designated SR 878, finally opened in early 1980, with the Southwest 72nd Avenue interchange opening a few weeks later. No tolls were collected along SR 878, in line with the road's original plans, until MDX 's initial roll-out of open road tolling from late 2009 to mid-2010 on its road network. Tolling along
11227-718: The same set of powers by the Florida Constitution and state law . Unlike a consolidated city-county , where the city and county governments merge into a single entity, these two entities are separate. Instead there are two "tiers", or levels, of government: city and county. There are 34 municipalities in the county, the City of Miami being the largest. Cities are the "lower tier" of local government, providing police and fire protection, zoning and code enforcement, and other typical city services within their jurisdiction. These services are paid for by city taxes. The County
11336-432: 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
11445-438: The three elections from 2008 to 2016; in 2008 and 2012 , Democrat Barack Obama averaged 59.69% of the vote. In 2016 , Democrat Hillary Clinton won 63.22% of the vote. However, in 2020 , Democrat Joe Biden only won 53.31% of the vote, winning the county by just over seven percent over Republican Donald Trump . This was attributed to a large swing of Cuban Americans , Venezuelan Americans , and other Hispanic Americans to
11554-406: 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,
11663-443: 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
