150-884: Interstate 95 ( I-95 ) is an Interstate Highway running along the East Coast of the United States from Miami, Florida , north to the Canadian border in Houlton, Maine . In the state of Delaware , the route runs for 23.43 miles (37.71 km) across the Wilmington area in northern New Castle County from the Maryland state line near Newark northeast to the Pennsylvania state line in Claymont . I-95

300-535: A concurrency or overlap. For example, I‑75 and I‑85 share the same roadway in Atlanta ; this 7.4-mile (11.9 km) section, called the Downtown Connector , is labeled both I‑75 and I‑85. Concurrencies between Interstate and US Highway numbers are also allowed in accordance with AASHTO policy, as long as the length of the concurrency is reasonable. In rare instances, two highway designations sharing

450-641: A diamond interchange was built instead. The first cloverleaf interchange built in the United States was the Woodbridge Cloverleaf at intersection of the Lincoln Highway ( Route 25 ) and Amboy —now St. Georges—Avenue ( Route 4 ) (now U.S. 1/9 and Route 35 ) in Woodbridge Township, New Jersey . It opened in 1929, although it has since been replaced with a partial cloverleaf interchange . Before

600-545: A "cloverleaf" and simply be referred to as a jughandle or parclo intersection. The first cloverleaf interchange patented in the US was by Arthur Hale , a civil engineer in Maryland , on February 29, 1916. A modified cloverleaf, with the adjacent ramps joined into a single two-way road, was planned in 1927 for the interchange between Lake Shore Drive ( US 41 ) and Irving Park Road ( ILL 19 ) in Chicago, Illinois , but

750-651: A 28-year-old brevet lieutenant colonel, accompanied the trip "through darkest America with truck and tank," as he later described it. Some roads in the West were a "succession of dust, ruts, pits, and holes." As the landmark 1916 law expired, new legislation was passed—the Federal Aid Highway Act of 1921 (Phipps Act). This new road construction initiative once again provided for federal matching funds for road construction and improvement, $ 75 million allocated annually. Moreover, this new legislation for

900-522: A 3–3–3–3 local–express lane configuration. This was later scaled down to a proposal to widen the road to eight lanes total. The widening of the Delaware Turnpike to eight lanes occurred in the 1980s. From 1971 to 1978, a north–south extension of the Delaware Turnpike running south to Dover was studied. This extension of the turnpike evolved into a "Relief Route" for US 13 and was built as DE 1 between 1987 and 2003. On June 28, 1978,

1050-485: A busy arterial in free-flowing traffic where signals are still not desired. Not only are these ideas true for new interchanges, but they also hold when existing cloverleaf interchanges are upgraded. In Norfolk, Virginia , the interchange between US 13 and US 58 was originally a cloverleaf—it has since been converted to a SPUI . Also, many cloverleaf interchanges on California freeways, such as U.S. 101, are being converted to parclos . In Hampton, Virginia ,

1200-427: A ceremony at the state line on November 14, 1963, in which a ribbon-cutting took place and a replica Mason–Dixon line crownstone was unveiled. The Delaware Turnpike was opened to traffic at midnight on November 15, 1963. The first motorist to pay a toll on the turnpike was Omero C. Catan, also known as "Mr. First", of Teaneck, New Jersey , who marked this occasion as the 517th first moment he achieved. The completion of

1350-476: A change in the numbering system as a result of a new policy adopted in 1973. Previously, letter-suffixed numbers were used for long spurs off primary routes; for example, western I‑84 was I‑80N, as it went north from I‑80 . The new policy stated, "No new divided numbers (such as I-35W and I-35E , etc.) shall be adopted." The new policy also recommended that existing divided numbers be eliminated as quickly as possible; however, an I-35W and I-35E still exist in

1500-548: A cloverleaf interchange between Interstate 64 and Mercury Boulevard has been partially unwound into a partial stack interchange. During 2008 and 2009, four cloverleaf interchanges along I-64 / US 40 in St. Louis , Missouri , were replaced with SPUIs as part of a major highway-renovation project to upgrade the highway to Interstate standards. The original cloverleaf interchange in Delmont, Pennsylvania between Routes 22 and 66

1650-677: A compromise of building the freeway through the city and would bring economic development to the Wilmington Riverfront. In August 1968, I-95 between the South Wilmington Viaduct and US 202 was completed and opened to traffic. On November 1, 1968, the freeway was opened between US 202 and the Pennsylvania state line. With this, the entire length of I-95 in Delaware was constructed, making Delaware

1800-476: A construction project began that will improve the DE ;273 interchange by realigning ramps and widening DE 273 through the interchange. Construction on this interchange improvement is planned to be completed in 2023. There are plans to reconstruct the interchange with DE 896 by adding two flyovers and realigning ramps in order to improve safety and congestion at the interchange. A groundbreaking ceremony

1950-608: A cost of $ 35 million (equivalent to $ 47.8 million in 2023). On September 17, 2018, the service plaza was renamed the Biden Welcome Center in honor of the Biden family , a Delaware political family that includes US Senator, 47th Vice President, and subsequently 46th President, Joe Biden . A renaming ceremony was held, with Governor John Carney and members of the Biden family (including Joe Biden) in attendance. At

2100-581: A directional ramp that intersects DE 202 at a signalized intersection. In addition, the interchange ramps were repaved and bridges were rehabilitated. The project was finished in July 2015, months behind schedule due to the closure of I-495 in 2014. On August 7, 2015, a dedication ceremony to mark the completion of the project was held, with Governor Markell, Senator Tom Carper , and DelDOT Secretary Jennifer Cohan in attendance. The project, which cost over $ 33 million (equivalent to $ 41.5 million in 2023),

2250-437: A group of state lawmakers led by Representative Sherry Dorsey Walker pushed for US Secretary of Transportation Pete Buttigieg , and, by proxy, President Joe Biden, to endorse a plan to add a freeway lid on top of I-95 through Wilmington and construct an urban park on top of the highway, reuniting neighborhoods that were divided when the highway was constructed. In April 2021, Wilmington city council unanimously approved backing

2400-572: A modified cloverleaf interchange with DE 273 west of Christiana . The freeway continues northeast and comes to a modified cloverleaf interchange with the DE ;1 / DE 7 freeway to the northwest of the Christiana Mall ; this interchange serves as the northern terminus of DE 1. This interchange has flyover ramps from southbound I-95 to southbound DE 1/DE 7 and from northbound DE 1/DE 7 to northbound I-95;

2550-480: A modified cloverleaf interchange with the northern terminus of DE 202 at the northern edge of Wilmington, at which point US 202 splits from I-95 to head north along Concord Pike. Past US 202, I-95 leaves Wilmington for the suburban Brandywine Hundred area and continues northeast as a four-lane road, passing southeast of the Rock Manor Golf Club and running along the northwest side of

2700-631: A new bridge over US 13/US 40 at the Farnhurst interchange in 1958 that would connect the Delaware Turnpike to the I-295/US ;40 approach to the Delaware Memorial Bridge. The same year, plans were made for several bridges along I-95. In 1959, work began on rebuilding the Farnhurst interchange to Interstate Highway standards . The same year, recommendations were made for the design and right-of-way acquisition along

2850-549: A northbound exit and southbound entrance with Harvey Road southeast of the villages of Arden , Ardentown , and Ardencroft . Past this interchange, the freeway curves east away from the CSX Transportation tracks and winds northeast near suburban neighborhoods in Claymont . In Claymont, the Interstate comes to a diamond interchange with DE 92 , at which point I-495 also merges onto the northbound direction of

3000-589: A numbering scheme in which primary Interstates are assigned one- or two-digit numbers, and shorter routes which branch off of longer ones are assigned three-digit numbers where the last two digits match the parent route. The Interstate Highway System is partially financed through the Highway Trust Fund , which itself is funded by a combination of a federal fuel tax and transfers from the Treasury's general fund. Though federal legislation initially banned

3150-402: A program of " urban renewal ". In the two decades following the 1956 Highway Act, the construction of the freeways displaced one million people, and as a result of the many freeway revolts during this era, several planned Interstates were abandoned or re-routed to avoid urban cores. Construction of the original Interstate Highway System was proclaimed complete in 1992, despite deviations from

3300-406: A project began to improve the interchange between I-95 and US 202/DE 202 in order to reduce congestion. The project widened the ramp between northbound I-95 and northbound US 202 to two lanes, the ramp between southbound US 202 and southbound I-95 was extended to modern standards, and the ramp between southbound I-95 and southbound DE 202 was relocated from a cloverleaf loop to

3450-559: A report called Toll Roads and Free Roads , "the first formal description of what became the Interstate Highway System" and, in 1944, the similarly themed Interregional Highways . The Interstate Highway System gained a champion in President Dwight D. Eisenhower, who was influenced by his experiences as a young Army officer crossing the country in the 1919 Motor Transport Corps convoy that drove in part on

3600-409: A single digit prefixed to the two-digit number of its parent Interstate Highway. Spur routes deviate from their parent and do not return; these are given an odd first digit. Circumferential and radial loop routes return to the parent, and are given an even first digit. Unlike primary Interstates, three-digit Interstates are signed as either east–west or north–south, depending on the general orientation of

3750-637: A six-lane freeway , through wooded areas. Not far from the Maryland state line, the road crosses Muddy Run before it comes to the Newark mainline toll plaza . I-95 widens to eight lanes and reaches a partial cloverleaf interchange with DE 896 , which heads north to Newark and the University of Delaware and south to Glasgow . Following this interchange, the Interstate Highway crosses

3900-801: A speed limit of 45 mph (70 km/h) because it is a parkway that consists of only one lane per side of the highway. On the other hand, Interstates 15, 80, 84, and 215 in Utah have speed limits as high as 70 mph (115 km/h) within the Wasatch Front , Cedar City , and St. George areas, and I-25 in New Mexico within the Santa Fe and Las Vegas areas along with I-20 in Texas along Odessa and Midland and I-29 in North Dakota along

4050-460: A speed limit of 80 mph (130 km/h). Other Interstates in Idaho, Montana, Oklahoma, South Dakota and Wyoming also have the same high speed limits. In some areas, speed limits on Interstates can be significantly lower in areas where they traverse significantly hazardous areas. The maximum speed limit on I-90 is 50 mph (80 km/h) in downtown Cleveland because of two sharp curves with

4200-474: A suggested limit of 35 mph (55 km/h) in a heavily congested area; I-70 through Wheeling, West Virginia , has a maximum speed limit of 45 mph (70 km/h) through the Wheeling Tunnel and most of downtown Wheeling; and I-68 has a maximum speed limit of 40 mph (65 km/h) through Cumberland, Maryland , because of multiple hazards including sharp curves and narrow lanes through

4350-521: A viable option for interchanges between freeways (where such devices are typically not an option), but they could also be used for very busy arterials where signals could present congestion problems. They are common in the United States and have been used for over 40 years as the Interstate Highway System expanded rapidly. One problem is that, frequently, large trucks exceeding the area speed limit roll over. Another problem

4500-485: A year later due to opposition. Following the completion of the Delaware Memorial Bridge connecting to the New Jersey Turnpike in 1951, through traffic coming from the bridge led to significant congestion on US 13 and US 40 . As a result of this, suggestions were made in 1954 for a limited-access road to be constructed leading to the bridge that would alleviate congestion on US 40. In 1956,

4650-543: Is also commonly believed the Interstate Highway System was built for the sole purpose of evacuating cities in the event of nuclear warfare . While military motivations were present, the primary motivations were civilian. The numbering scheme for the Interstate Highway System was developed in 1957 by the American Association of State Highway and Transportation Officials (AASHTO). The association's present numbering policy dates back to August 10, 1973. Within

4800-534: Is in Lakewood, Washington , at the interchange between Interstate 5 and Washington State Route 512 , where a visible ramp stub shows that one of the four leaves was removed, thus eliminating weave on I-5. In the future, the traffic signal will be replaced by a two-lane flyover, completing the freeway-to-freeway interchange once again. Cloverleaf interchanges also tend to occupy much more land than any other kind of interchange. Numerous cloverleaf intersections in

Kamener Kreuz was the first in continental Europe to open fully in 1937, at A 1 and A 2 near Dortmund , Germany . The primary drawback of the classic design of the cloverleaf is that vehicles merge onto the highway at the end of a loop immediately before other vehicles leave to go around another loop, creating conflict known as weaving . Weaving limits

Examples include the Highway 62 and Highway 401 interchange in Belleville, Ontario , the Highway 4 and Highway 401 in London, Ontario , as well as the Lawrence Avenue and Don Valley Parkway interchange in Toronto. The Don Mills Road and Don Valley Parkway and the Highway 27 and Dixon Road are also other examples; however, one quadrant of each has

The first cloverleaf west of the Mississippi River opened on August 20, 1931, at Watson Road and Lindbergh Boulevard near St. Louis, Missouri , as part of an upgrade of U.S. 66 . The first cloverleaf interchange in Canada opened in 1937 at the junction of the Queen Elizabeth Way (QEW) and Provincial Highway 10 in Port Credit, Ontario (now a part of Mississauga, Ontario). As originally built, Highway 10 passed over

However, AASHTO disapproved renumbering the alignment of I-95 through Wilmington as I-595. On October 27 of that year, AASHTO gave conditional approval for I-95 through Wilmington to be designated as I-195 from I-95 near Newport north to US 202 while the route from US 202 north to I-95 in Claymont would become I-395.

6900-549: The Lower Mainland of British Columbia, Canada, require the merging of traffic from the clover directly onto the collector/distributor lane. This requires the slowly moving driver coming around the loop ramp to merge with the quickly moving driver exiting on the collector/distributor lane with no opportunity to accelerate to match the flow of the oncoming driver. This speed differential in merging can be as great as 65 km/h (approx. 43 mph). The cloverleaf interchange

In June of that year, the substructure of the I-95 bridge over the Brandywine Creek was completed. In August 1964, construction began on the I-95 interchange with Naamans Road and the northern terminus of I-495 in Claymont. In 1965, construction was underway to build

8550-585: The Christina River. After this bridge, I-95 has a northbound ramp to Airport Road that serves to provide access to southbound US 202 / DE 141 . At this point, the lanes of the Interstate split further apart, and the northbound ramp for I-295 and northbound DE 141 exits off to parallel the northbound lanes of I-95. The ramp to northbound I-295 has two lanes while northbound I-95 carries four lanes. After this, I-95 crosses US 202/DE 141 at an interchange, at which point US 202 becomes concurrent with I-95. Upon crossing US 202/DE 141,

As a result, the state of Delaware financed the road with bond issues and would build it as a toll road called the Delaware Turnpike. The first construction contracts for the Delaware Turnpike were awarded in 1957, with construction soon following that year. Construction began on building

9750-491: The I-95 interchange opened in November 1962. The southbound lanes of DE 41/DE 141 opened in June 1964, enabling directional flow of DE 41/DE 141 through the interchange. In September 1963, construction work on the turnpike was halted by picketing workers. The Delaware Turnpike, along with the connecting Northeast Expressway in Maryland, was dedicated by President John F. Kennedy , Delaware Governor Elbert N. Carvel , and Maryland Governor J. Millard Tawes in

10800-779: The QEW. In 1962, the interchange was rebuilt with sub-collector roads along the QEW, and the orientation was also changed so that Highway 10 then passed under the QEW. The interchange was further modified between 2008 and 2010 by removing all but one loop ramp, creating a partial cloverleaf/diamond hybrid. The cloverleaf was patented in Europe in Switzerland on October 15, 1928. The first cloverleaf in Europe opened in October 1935 at Slussen in central Stockholm , Sweden , followed in 1936 by Schkeuditzer Kreuz near Leipzig , Germany . This

10950-806: The US to determine the difficulties that military vehicles would have on a cross-country trip. Leaving from the Ellipse near the White House on July 7, the Motor Transport Corps convoy needed 62 days to drive 3,200 miles (5,100 km) on the Lincoln Highway to the Presidio of San Francisco along the Golden Gate . The convoy suffered many setbacks and problems on the route, such as poor-quality bridges, broken crankshafts, and engines clogged with desert sand. Dwight Eisenhower , then

11100-715: The United States, including: In addition to cancellations, removals of freeways are planned: The American Association of State Highway and Transportation Officials (AASHTO) has defined a set of standards that all new Interstates must meet unless a waiver from the Federal Highway Administration (FHWA) is obtained. One almost absolute standard is the controlled access nature of the roads. With few exceptions , traffic lights (and cross traffic in general) are limited to toll booths and ramp meters (metered flow control for lane merging during rush hour ). Being freeways , Interstate Highways usually have

11250-481: The act was signed, and paving started September 26, 1956. The state marked its portion of I-70 as the first project in the United States completed under the provisions of the new Federal-Aid Highway Act of 1956. The Pennsylvania Turnpike could also be considered one of the first Interstate Highways, and is nicknamed "Grandfather of the Interstate System". On October 1, 1940, 162 miles (261 km) of

11400-638: The below-surface alignment of I-95 between Fourth Street and the Brandywine Creek in Wilmington. The construction of I-95 through Wilmington resulted in the demolition of 360 to 370 homes in the West Side neighborhood between Adams and Jackson streets. The construction of the highway led to the decline of the residential and commercial base in Wilmington. Work was also underway on the portion of I-95 northeast of Wilmington, which would parallel

11550-624: The cancellation of the Somerset Freeway . This situation was remedied when the construction of the Pennsylvania Turnpike/Interstate 95 Interchange Project started in 2010 and partially opened on September 22, 2018, which was already enough to fill the gap. However, I-70 remains discontinuous in Pennsylvania , because of the lack of a direct interchange with the Pennsylvania Turnpike at

11700-503: The central core and instead suggested routing it along Bancroft Parkway to the west or the present-day route of I-495 to the east. However, the lame-duck Republican -controlled city council approved routing I-95 along Adams and Jackson streets in 1957. The demolition of homes began in January 1959. A year later, construction began on overpasses and ramps at the Farnhurst interchange. The same year, suggestions were made to build I-95 across

11850-571: The ceremony, Governor Carney signed a bill formally renaming the service plaza. In 1948, the Wilmington Transportation Study proposed two new roads running between the southern end of Wilmington and the Pennsylvania state line to improve traffic flow in the Wilmington area. Route A followed the current alignment of I-95 while Route B bypassed the city to the east along the current alignment of I-495. Plans for building Route A were made in 1950 but were deferred

12000-617: The city. In some locations, low speed limits are the result of lawsuits and resident demands; after holding up the completion of I-35E in St. Paul, Minnesota , for nearly 30 years in the courts, residents along the stretch of the freeway from the southern city limit to downtown successfully lobbied for a 45 mph (70 km/h) speed limit in addition to a prohibition on any vehicle weighing more than 9,000 pounds (4,100 kg) gross vehicle weight . I-93 in Franconia Notch State Park in northern New Hampshire has

12150-611: The cloverleaf was replaced in the late 2000s, it was judged eligible for inclusion in the National Register of Historic Places . Because of this, a commemorative film was made of the cloverleaf. The original cloverleaf interchange design was adapted by the Rudolph and Delano building firm from Philadelphia , from a photo Delano saw on a magazine cover about a highway in Buenos Aires , Argentina . The original inventor

12300-401: The collection of tolls, some Interstate routes are toll roads , either because they were grandfathered into the system or because subsequent legislation has allowed for tolling of Interstates in some cases. As of 2022 , about one quarter of all vehicle miles driven in the country used the Interstate Highway System, which has a total length of 48,890 miles (78,680 km). In 2022 and 2023,

12450-507: The construction and improvement of highways. The nation's revenue needs associated with World War I prevented any significant implementation of this policy, which expired in 1921. In December 1918, E. J. Mehren, a civil engineer and the editor of Engineering News-Record , presented his "A Suggested National Highway Policy and Plan" during a gathering of the State Highway Officials and Highway Industries Association at

12600-407: The contiguous United States, primary Interstates—also called main line Interstates or two-digit Interstates—are assigned numbers less than 100. While numerous exceptions do exist, there is a general scheme for numbering Interstates. Primary Interstates are assigned one- or two-digit numbers, while shorter routes (such as spurs, loops, and short connecting roads) are assigned three-digit numbers where

12750-401: The country's economy, defense, and mobility. I-95 has a mainline toll plaza along the Delaware Turnpike near the Maryland state line in Newark. Cash or E-ZPass is accepted for payment of tolls. The plaza is staffed by toll collectors and also features high-speed E-ZPass lanes. The toll for passenger vehicles costs $ 4.00 both northbound and southbound. When the highway first opened in 1963,

12900-623: The discontinuity, but they have been blocked by local opposition, fearing a loss of business. The Interstate Highway System has been expanded numerous times. The expansions have both created new designations and extended existing designations. For example, I-49 , added to the system in the 1980s as a freeway in Louisiana , was designated as an expansion corridor, and FHWA approved the expanded route north from Lafayette, Louisiana , to Kansas City, Missouri . The freeway exists today as separate completed segments, with segments under construction or in

13050-448: The dissemination of public information. As a result, the 2005 evacuation of New Orleans, Louisiana, prior to Hurricane Katrina ran much more smoothly. According to urban legend , early regulations required that one out of every five miles of the Interstate Highway System must be built straight and flat, so as to be usable by aircraft during times of war. There is no evidence of this rule being included in any Interstate legislation. It

13200-408: The downtown area and the Wilmington Riverfront. At this point, the four-lane freeway continues northeast, with one-way northbound North Adams Street to the east and one-way southbound North Jackson Street to the west serving as frontage roads . I-95/US 202 continues through residential areas to the west of downtown Wilmington and passes over DE 9 , with a southbound exit. Farther northeast,

13350-496: The eastern end of the concurrency near Breezewood . Traveling in either direction, I-70 traffic must exit the freeway and use a short stretch of US 30 (which includes a number of roadside services) to rejoin I-70. The interchange was not originally built because of a legacy federal funding rule, since relaxed, which restricted the use of federal funds to improve roads financed with tolls. Solutions have been proposed to eliminate

13500-450: The economy. Not just as a public works measure, but for future growth. Clay's committee proposed a 10-year, $ 100 billion program ($ 1.13 trillion in 2023), which would build 40,000 miles (64,000 km) of divided highways linking all American cities with a population of greater than 50,000. Eisenhower initially preferred a system consisting of toll roads , but Clay convinced Eisenhower that toll roads were not feasible outside of

13650-522: The enactment of the Federal-Aid Highway Act of 1956 . Unlike the earlier United States Numbered Highway System, the interstates were designed to be all freeways, with nationally unified standards for construction and signage. While some older freeways were adopted into the system, most of the routes were completely new. In dense urban areas, the choice of routing destroyed many well-established neighborhoods, often intentionally as part of

13800-525: The entrance from 2nd Street was rebuilt. At times during construction, the highway was reduced to two lanes of traffic. Construction was finished in November 2022, months ahead of schedule. On April 6, 2023, a ceremony marking the completion of the project was held, with Governor Carney, Senators Carper and Chris Coons , Representative Lisa Blunt Rochester , Wilmington Mayor Mike Purzycki , and DelDOT Secretary Nicole Majeski in attendance. On March 15, 2021,

13950-492: The existing, largely non-freeway, United States Numbered Highways system. By the late 1930s, planning had expanded to a system of new superhighways. In 1938, President Franklin D. Roosevelt gave Thomas MacDonald , chief at the Bureau of Public Roads, a hand-drawn map of the United States marked with eight superhighway corridors for study. In 1939, Bureau of Public Roads Division of Information chief Herbert S. Fairbank wrote

14100-426: The federal government, Interstate Highways are owned by the state in which they were built. With few exceptions , all Interstates must meet specific standards , such as having controlled access, physical barriers or median strips between lanes of oncoming traffic, breakdown lanes , avoiding at-grade intersections , no traffic lights , and complying with federal traffic sign specifications. Interstate Highways use

14250-515: The first three contracts under the new program were signed in Missouri on August 2, 1956. The first contract signed was for upgrading a section of US Route 66 to what is now designated Interstate 44 . On August 13, 1956, work began on US 40 (now I-70) in St. Charles County. Kansas claims that it was the first to start paving after the act was signed. Preliminary construction had taken place before

14400-614: The first time sought to target these funds to the construction of a national road grid of interconnected "primary highways", setting up cooperation among the various state highway planning boards. The Bureau of Public Roads asked the Army to provide a list of roads that it considered necessary for national defense. In 1922, General John J. Pershing , former head of the American Expeditionary Force in Europe during

14550-426: The former toll booths at the DE 273 and DE 7 interchanges; however, the DE 896 interchange toll booths were to remain to collect tolls from trucks. The mainline toll plaza was planned to be closed on July 1, 1981, after the bonds to construct the road were paid off, but was kept by "Operation Overhaul", a $ 93-million (equivalent to $ 264 million in 2023) project by Governor Pete du Pont that would use

14700-482: The freeway heads into an alignment below street level and comes to an interchange with DE 52 . Past this interchange, the road heads to the north and crosses Brandywine Creek , heading through Brandywine Park , which is a part of the Wilmington State Parks complex. The freeway curves northeast again and passes under CSX Transportation 's Philadelphia Subdivision railroad line before reaching

14850-489: The highest speed limits in a given area. Speed limits are determined by individual states. From 1975 to 1986, the maximum speed limit on any highway in the United States was 55 miles per hour (90 km/h), in accordance with federal law. Typically, lower limits are established in Northeastern and coastal states, while higher speed limits are established in inland states west of the Mississippi River . For example,

15000-553: The highly populated coastal regions. In February 1955, Eisenhower forwarded Clay's proposal to Congress. The bill quickly won approval in the Senate, but House Democrats objected to the use of public bonds as the means to finance construction. Eisenhower and the House Democrats agreed to instead finance the system through the Highway Trust Fund , which itself would be funded by a gasoline tax. In June 1956, Eisenhower signed

15150-617: The highway now designated I‑70 and I‑76 opened between Irwin and Carlisle . The Commonwealth of Pennsylvania refers to the turnpike as the Granddaddy of the Pikes, a reference to turnpikes . Milestones in the construction of the Interstate Highway System include: The initial cost estimate for the system was $ 25 billion over 12 years; it ended up costing $ 114 billion (equivalent to $ 425 billion in 2006 or $ 618 billion in 2023 ) and took 35 years. The system

15300-415: The highway. The service plaza offers a Sunoco gas station, electric vehicle charging stations , a convenience store , multiple fast-food restaurants , a visitor center , and retail options including a store called Postcards from Delaware that sells Delaware-related merchandise. There is also a Tesla Supercharger station at the Biden Welcome Center. The Biden Welcome Center is run by Applegreen . When

15450-459: The inefficiency of evacuating from southern Louisiana prior to Hurricane Georges ' landfall in September 1998, government officials looked towards contraflow to improve evacuation times. In Savannah, Georgia , and Charleston, South Carolina , in 1999, lanes of I-16 and I-26 were used in a contraflow configuration in anticipation of Hurricane Floyd with mixed results. In 2004, contraflow

15600-455: The interchange along with the adjacent section of DE 141 was completed in December 2021. DelDOT completely rebuilt I-95 from the southern end of I-495 to the Brandywine Creek bridge in Wilmington in a $ 200-million project beginning in February 2021. Several overpasses were repaired and new guardrails were installed. The southbound entrance ramp from South Jackson Street was demolished and

15750-433: The interstate via a southbound exit and northbound entrance. The southbound exit to DE 92 is via the I-495 interchange while all other ramps of the DE 92 interchange connect directly to I-95. Following the interchange, I-95 passes to the west of the former Tri-State Mall before it crosses the state line into Pennsylvania . The southbound exit from I-95 to I-495 is located in Pennsylvania, 132 feet (40 m) before

15900-431: The last two digits match the parent route (thus, I-294 is a loop that connects at both ends to I-94 , while I-787 is a short spur route attached to I-87 ). In the numbering scheme for the primary routes, east–west highways are assigned even numbers and north–south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north (to avoid confusion with

16050-535: The mainline toll plaza along I-95 due to the COVID-19 pandemic , with all tolls collected electronically through the high-speed E-ZPass lanes and motorists without E-ZPass billed by mail; cash tolls resumed on May 21, 2020. The Biden Welcome Center (formerly Delaware Welcome Center and also referred to as Delaware House) service plaza is located in the median of I-95 between the DE 896 and DE 273 interchanges east of Newark, with access from both directions of

16200-454: The mainline. Some auxiliary highways do not follow these guidelines, however. The Interstate Highway System also extends to Alaska , Hawaii , and Puerto Rico , even though they have no direct land connections to any other states or territories. However, their residents still pay federal fuel and tire taxes. The Interstates in Hawaii, all located on the most populous island of Oahu , carry

16350-753: The maximum speed limit is 75 mph (120 km/h) in northern Maine, varies between 50 and 70 mph (80 and 115 km/h) from southern Maine to New Jersey, and is 50 mph (80 km/h) in New York City and the District of Columbia. Currently, rural speed limits elsewhere generally range from 65 to 80 miles per hour (105 to 130 km/h). Several portions of various highways such as I-10 and I-20 in rural western Texas, I-80 in Nevada between Fernley and Winnemucca (except around Lovelock) and portions of I-15 , I-70 , I-80 , and I-84 in Utah have

16500-837: The north, passing to the west of Daniel S. Frawley Stadium , which is home of the Wilmington Blue Rocks baseball team, and the Chase Center on the Riverfront convention center as it heads west of the Wilmington Riverfront . I-95/US 202 heads toward downtown Wilmington and crosses onto a viaduct, passing over Norfolk Southern Railway's Wilmington & Northern Running Track and the Northeast Corridor before coming to an interchange with DE 4 and DE 48 that provides access to

16650-442: The northbound lanes of I-495 reopened on August 23. In 2016, a project began to improve the interchange with DE 141. The project reconstructed the bridges that carry DE 141 over I-95 and added safety improvements to the interchange ramps. In June 2016, the ramp from northbound I-95 to northbound DE 141 closed until June 2017 to allow for reconstruction of the bridge along northbound DE 141. Construction on improving

16800-569: The northbound ramp splits onto both sides of the northbound lanes of I-95. The interchange with DE 1/DE 7 also has access to the Christiana Mall via ramps connecting to Mall Road. Past this interchange, I-95 widens to 10 lanes and passes under DE 58 , with a ramp from southbound I-95 to DE 58 that provides the missing connection between southbound I-95 and northbound DE 7. The highway continues through woods before heading through Churchman's Marsh, where it crosses

16950-404: The number of fatalities on the Interstate Highway System amounted to more than 5,000 people annually, with nearly 5,600 fatalities in 2022. The United States government's efforts to construct a national network of highways began on an ad hoc basis with the passage of the Federal Aid Road Act of 1916 , which provided $ 75 million over a five-year period for matching funds to the states for

17100-441: The number of lanes of turning traffic. Most road authorities have since been implementing new interchange designs with less-curved exit ramps that do not result in weaving. These interchanges include the diamond , parclo and single-point urban interchanges (SPUI) when connecting to an arterial road in non free-flowing traffic on the crossroad and the stack or clover and stack hybrids when connecting to another freeway or to

17250-478: The official Interstate Highway standards . On one- or two-digit Interstates, the mile marker numbering almost always begins at the southern or western state line. If an Interstate originates within a state, the numbering begins from the location where the road begins in the south or west. As with all guidelines for Interstate routes, however, numerous exceptions exist. Cloverleaf interchange Cloverleaf interchanges, viewed from overhead or on maps, resemble

17400-407: The one-year anniversary of the dedication of the Delaware Turnpike on November 14, 1964, a memorial service and wreath laying in honor of Kennedy was held at the state line, with Governor Carvel in attendance. The remainder of I-95 between the Christina River interchange and the Pennsylvania state line was built as a non-tolled freeway. In April 1964, construction contracts were awarded for bridges at

17550-465: The original 1956 plan and several stretches that did not fully conform with federal standards . The construction of the Interstate Highway System cost approximately $ 114 billion (equivalent to $ 618 billion in 2023). The system has continued to expand and grow as additional federal funding has provided for new routes to be added, and many future Interstate Highways are currently either being planned or under construction. Though heavily funded by

17700-664: The plan for constructing an urban park over I-95 through the city. The entire route is in New Castle County . I-95 has two auxiliary routes that are located within the state of Delaware. I-295 runs from I-95 near Newport east (north) to the Delaware Memorial Bridge , where it crosses the Delaware River into New Jersey . Once in New Jersey, I-295 intersects the southern terminus of

17850-432: The planned route of I-95 as well as the construction of several contracts between the Maryland state line and Farnhurst along the Delaware Turnpike, including the interchange with DE 41 /DE 141 and between I-95, I-295, and I-495 near the Christina River. The proposed routing for I-95 through Wilmington would take it through the central core between Adams and Jackson streets. Locals tried to fight routing I-95 through

18000-656: The planning phase between them. In 1966, the FHWA designated the entire Interstate Highway System as part of the larger Pan-American Highway System, and at least two proposed Interstate expansions were initiated to help trade with Canada and Mexico spurred by the North American Free Trade Agreement (NAFTA). Long-term plans for I-69 , which currently exists in several separate completed segments (the largest of which are in Indiana and Texas ),

18150-411: The prefix H . There are three one-digit routes in the state ( H-1 , H-2 , and H-3 ) and one auxiliary route ( H-201 ). These Interstates connect several military and naval bases together, as well as the important communities spread across Oahu, and especially within the urban core of Honolulu . Both Alaska and Puerto Rico also have public highways that receive 90 percent of their funding from

18300-513: The proper change at the tollbooth to pay the tolls by mailing them. However, it was discontinued after a month because most motorists did not mail in their tolls. In 1976, Governor Sherman W. Tribbitt signed House Bill 1278, which was sponsored by Representative Gerard A. Cain. This bill called for the elimination of the three ramp tolls while keeping the mainline toll plaza near the Maryland state line. The ramp tolls stopped being collected on October 1, 1976. In 1981, plans were announced to demolish

18450-402: The ramp to northbound DE 141 from the northbound I-295 ramp splits off while the ramp from US 202/DE 141 to northbound I-95 merges in from the left. Southbound, a collector–distributor road serves to provide access between I-95 and US 202/DE 141. Not far after encountering US 202/DE 141, I-295 splits off to the southeast, with the northbound entrance from I-295,

18600-618: The reduction in profits for businesses along US 13 and US 40, with several businesses forced to close. Meanwhile, the Delaware Turnpike saw more traffic volume than originally projected. Eight days after dedicating the toll road, President Kennedy was assassinated in Dallas . As a result, both the Delaware Turnpike and the Northeast Expressway were renamed the John F. Kennedy Memorial Highway in his honor in December 1963. On

18750-436: The remainder reopening in October. During the closure, through traffic was detoured to I-495. In 2003, construction began on a new bridge carrying DE 58 over I-95 to replace the previous bridge, which was over 40 years old and experienced deterioration. Construction of the new bridge, which cost $ 17 million (equivalent to $ 24.7 million in 2023), was originally planned to be finished in late 2005 but completion

18900-515: The road. A few cloverleaf interchanges in California have been rebuilt to eliminate weaving on the freeway while keeping all four loop ramps, by adding bridges, similar to braided ramps. Several cloverleaf interchanges have been eliminated by adding traffic lights on the non-freeway route. Sometimes, this is even done at the intersection of two freeways, particularly when one freeway terminates at an interchange with another. An example of this

19050-426: The route through Wilmington was designated as Interstate 895 ( I-895 ). Improvements continue to be made to the highway including widening projects and reconstruction of sections of the road and interchanges. I-95 enters Delaware from Maryland southwest of the city of Newark in New Castle County . From the state line, the highway heads east (north) as the Delaware Turnpike (John F. Kennedy Memorial Highway),

19200-478: The route, without regard to the route number. For instance, I-190 in Massachusetts is labeled north–south, while I-195 in New Jersey is labeled east–west. Some looped Interstate routes use inner–outer directions instead of compass directions, when the use of compass directions would create ambiguity. Due to the large number of these routes, auxiliary route numbers may be repeated in different states along

19350-419: The same numbers, which is generally disallowed under highway administration guidelines. Several two-digit numbers are shared between unconnected road segments at opposite ends of the country for various reasons. Some such highways are incomplete Interstates (such as I-69 and I-74 ) and some just happen to share route designations (such as I-76 , I-84 , I‑86 , I-87 , and I-88 ). Some of these were due to

19500-503: The same roadway are signed as traveling in opposite directions; one such wrong-way concurrency is found between Wytheville and Fort Chiswell , Virginia, where I‑81 north and I‑77 south are equivalent (with that section of road traveling almost due east), as are I‑81 south and I‑77 north. Auxiliary Interstate Highways are circumferential, radial, or spur highways that principally serve urban areas . These types of Interstate Highways are given three-digit route numbers, which consist of

19650-477: The six-lane Wilmington Expressway, crossing the Christina River. The freeway comes to bridges over Norfolk Southern Railway's Shellpot Secondary railroad line and Little Mill Creek as it continues through more wetlands west of the Russell W. Peterson Urban Wildlife Refuge, with Amtrak 's Northeast Corridor railroad line running parallel a short distance to the northwest. The road enters Wilmington and curves to

19800-468: The southbound exit to I-295, and the southbound entrance from I-295 on the left side of the road. At this point, the Delaware Turnpike comes to its northern terminus. After I-295, I-95/US 202 turns north and comes to a northbound exit and southbound entrance with the southern terminus of I-495 , which bypasses the city of Wilmington to the east. Following the I-495 interchange, the median narrows and I-95/US 202 heads northeast through marshland as

19950-529: The southern termini of I-295 and I-495. I-95 becomes the Wilmington Expressway from here to the Pennsylvania state line and heads north through Wilmington concurrently with U.S. Route 202 (US 202). Past Wilmington, I-95 continues northeast to Claymont, where I-495 rejoins the route right before the Pennsylvania state line. Plans for a road along the I-95 corridor through Wilmington to

20100-407: The third state to complete its section of I-95. In November 1968, work began to widen the Delaware Turnpike from four to six lanes to handle increasing traffic volumes. The widening project was completed in December 1969, one year ahead of schedule. In 1969, a plan was made to widen the turnpike between DE 896 and DE 273 to 10 lanes and between DE 273 and DE 141 to 12 lanes in

20250-408: The toll at the toll plaza near the state line was $ 0.30 (equivalent to $ 2.99 in 2023). Prior to 1976, ramp tolls were collected at the DE 896, DE 273, and DE 7 interchanges. The ramp tolls required exact change, and many motorists were caught by police evading the tolls because they did not have the proper change. In 1970, an attempt was made to use the honor system for motorists without

20400-493: The tolls collected at the toll plaza to fund improvements to the turnpike along with other roads in the state of Delaware. In the middle of 2011, reconstruction of the Delaware Turnpike toll plaza was completed in a $ 32.6-million (equivalent to $ 43.6 million in 2023) project funded by the American Recovery and Reinvestment Act of 2009 , adding high-speed E-ZPass lanes. On March 17, 2020, cash tolls were suspended at

20550-495: The war, complied by submitting a detailed network of 20,000 miles (32,000 km) of interconnected primary highways—the so-called Pershing Map . A boom in road construction followed throughout the decade of the 1920s, with such projects as the New York parkway system constructed as part of a new national highway system. As automobile traffic increased, planners saw a need for such an interconnected national system to supplement

20700-513: Was redesigned in 2019 to remove one of the loops. In Ireland , partial cloverleaf set-ups exist at the interchanges of the main roads out of Dublin and the M50, allowing free-flow movements in all directions. The Red Cow Interchange is an example. Most cloverleaf interchanges have been phased out in Ontario, but some close variants do remain with similar traffic flows. The main difference however

20850-423: Was 80-percent funded by the federal government. On June 2, 2014, the I-495 bridge over the Christina River was closed after it was discovered that four support columns were tilting. During this closure, traffic from I-495 was detoured onto I-95, and several major roads in the Wilmington area experienced increased traffic congestion. The southbound lanes of I-495 reopened on July 31, a month earlier than expected, and

21000-591: Was also converted to an SPUI . A compromise is to add a collector/distributor road next to the freeway; this does not eliminate weaving but moves it off the main lanes of the freeway. An example of this is the State Highway 23 / Interstate 43 interchange in Sheboygan, Wisconsin , where the exit/entrance roads on and off Highway 23 are two lanes next to the main I-43 freeway on the north and southbound sides of

21150-470: Was completed in March 2012, with a newly built bridge over DE 1, just south of the I-95 interchange. The ramp from southbound I-95 to southbound DE 1/DE 7 opened on August 27, 2013, and the ramp from northbound DE 1/DE 7 to northbound I-95 opened on October 17, 2013, with a ribbon-cutting ceremony attended by Governor Jack Markell and DelDOT Secretary Shailen Bhatt . In December 2011,

21300-526: Was delayed to late 2006. The new bridge carrying DE 58 over I-95 was built to accommodate future widening of I-95. In May 2007, construction began to widen I-95 between the DE 1/DE 7 and US 202/DE 141 interchanges from eight to ten lanes due to rising traffic levels and increased development. The widening project was completed in November 2008. Traffic congestion at the cloverleaf interchange with DE 1/DE 7 in Christiana led to

21450-406: Was designated along the conditionally approved route of I-195 and I-395 on June 25, 1979. In 1980, the South Wilmington Viaduct was reconstructed. On November 14, 1980, I-95 and I-495 were returned to their original alignments, with I-895 decommissioned. US 202 was designated concurrent with I-95 through Wilmington in 1984. In 2000, I-95 was completely rebuilt between US 202/DE 202 and

21600-551: Was employed ahead of Hurricane Charley in the Tampa, Florida area and on the Gulf Coast before the landfall of Hurricane Ivan ; however, evacuation times there were no better than previous evacuation operations. Engineers began to apply lessons learned from the analysis of prior contraflow operations, including limiting exits, removing troopers (to keep traffic flowing instead of having drivers stop for directions), and improving

21750-437: Was established, creating the first national road numbering system for cross-country travel. The roads were state-funded and maintained, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower became president in 1953, his administration developed a proposal for an interstate highway system, eventually resulting in

21900-444: Was held on May 1, 2023, with Governor Carney, Senator Carper, Representative Blunt Rochester, and DelDOT Secretary Majeski in attendance. The reconstruction project, which is projected to cost $ 143 million, began on May 7, 2023, and is planned to be completed in 2026. The project received a $ 57-million grant from the US Department of Transportation which allowed construction to begin earlier than originally planned. In March 2021,

22050-707: Was not implemented in great numbers in the United Kingdom , because of these performance problems. There were originally three, one in Redditch and two in Livingston . One of the Livingston examples was remodeled in the mid-2000s as part of a public transport project. The Girton interchange near Cambridge was a "half"-cloverleaf interchange that regularly experienced peak-time congestion due to A14 westbound traffic weaving with M11 traffic. This interchange

22200-422: Was proclaimed complete in 1992, but two of the original Interstates— I-95 and I-70 —were not continuous: both of these discontinuities were due to local opposition, which blocked efforts to build the necessary connections to fully complete the system. I-95 was made a continuous freeway in 2018, and thus I-70 remains the only original Interstate with a discontinuity. I-95 was discontinuous in New Jersey because of

22350-494: Was serving as Supreme Commander of Allied Forces in Europe during World War II . In 1954, Eisenhower appointed General Lucius D. Clay to head a committee charged with proposing an interstate highway system plan. Summing up motivations for the construction of such a system, Clay stated, It was evident we needed better highways. We needed them for safety, to accommodate more automobiles. We needed them for defense purposes, if that should ever be necessary. And we needed them for

22500-548: Was the largest Roy Rogers and Bob's Big Boy location at the time and restaurant namesake Roy Rogers and Lieutenant Governor Mike Castle were in attendance for the opening. In September 2009, the Delaware Welcome Center was closed for a reconstruction project that built a new service plaza building, new gas pumps, new truck parking, and an improved visitor center. The renovated service plaza opened in June 2010 at
