100-824: Interstate 80 ( I-80 ) is a major interstate highway in the United States , running from San Francisco, California , eastward to the New York metropolitan area . In New Jersey , I-80 runs for 68.3 miles (109.9 km) from the Delaware Water Gap Toll Bridge at the Pennsylvania state line to its eastern terminus at the interchange with the New Jersey Turnpike ( I-95 ) in Teaneck , Bergen County . I-95 continues from

200-535: 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

300-650: A weigh station in the eastbound direction. After turning southeast and leaving the Delaware Water Gap, the road has a westbound right-in/right-out for Hainesburg Road before crossing under the abandoned Delaware River Viaduct of the Lackawanna Cut-Off . East of the viaduct, I-80 widens to six lanes and reaches a complex interchange with the western terminus of US 46 , Route 94 , and Decatur Street in Columbia , where development near

400-651: 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

500-808: A 60-foot (18 m) metal fence between milemarker 1.0 and 1.0 to prevent rocks from falling onto the highway. On June 22, 2001, a tanker crashed on a westbound bridge on I-80 in Denville, causing a fiery explosion that damaged the bridge and forced its demolition. A temporary bridge had to be built, and traffic on this part of I-80 as well as adjacent roads was snarled; in addition, a state of emergency had been declared for Morris County. The new I-80 bridge opened in September 2001. I-80, like many other highways in New Jersey, once had solar powered emergency callboxes every one mile (1.6 km), however, with

600-476: 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

700-608: A complex array of ramps. In 1982, two rest areas along I-80 were closed due to chronic use for illegal activities. The rest area in Lodi , next to westbound exit 63, closed on June 30, and the rest area at Roxbury in Morris County closed in October. However, the latter reopened on August 14, 1991, for trucks only. In the 1990s, HOV lanes were built along I-80 between Rockaway and Parsippany. These HOV lanes, along with

800-589: 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

900-491: A proposal for an interstate highway system, eventually resulting in 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,

1000-559: 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

1100-409: 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

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

1300-460: 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

1400-474: 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

1500-643: A turn to the northeast, the highway comes into Fairfield , Essex County , continuing through wooded surroundings as it heads north before turning east. Development near the road increases as it comes to the westbound exit and eastbound entrance with Two Bridges Road ( CR 613 ). After crossing the Passaic River again, I-80 enters Wayne in Passaic County . Here, the road passes under the Montclair-Boonton Line before coming to

1600-586: A viaduct, crossing over the NJ Transit's Main Line before coming to the exit for Madison Avenue ( CR 649 ). The road returns to ground level near urban neighborhoods as it comes to an eastbound exit and westbound entrance serving Market Street before reaching an interchange with Route 20 . After a fourth crossing of the Passaic River, I-80 comes into Elmwood Park in Bergen County and reaches

1700-543: 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

1800-543: Is also applied sometimes to I-95/Turnpike north of the I-80 interchange), was incorporated into I-80. The freeway was built across New Jersey in stages from the 1960s to 1973. The westernmost four miles (6.4 km) in New Jersey was originally a rerouting of US 611 when built, although that route was later realigned back into Pennsylvania. In the 1990s, HOV lanes had existed on a part of I-80 in Morris County, but

1900-458: Is located in the eastbound direction. Upon crossing into Blairstown , the eastbound direction narrows down to three lanes. In Hope Township , I-80 reaches an interchange with CR 521 that also provides access to CR 519 and the Land of Make Believe amusement park. The highway widens to eight lanes briefly after this interchange before narrowing to six lanes. In Frelinghuysen Township ,

The planned I-11 will then bridge the Interstate gap between Phoenix, Arizona and Las Vegas, Nevada , and thus form part of the CANAMEX Corridor (along with I-19 , and portions of I-10 and I-15 ) between Sonora , Mexico and Alberta , Canada. Political opposition from residents canceled many freeway projects around

2100-474: The Dallas–Fort Worth metroplex in Texas, and an I-35W and I-35E that run through Minneapolis and Saint Paul , Minnesota, still exist. Additionally, due to Congressional requirements, three sections of I-69 in southern Texas will be divided into I-69W , I-69E , and I-69C (for Central). AASHTO policy allows dual numbering to provide continuity between major control points. This is referred to as

2200-552: The Federal Aid Highway Act of 1956 into law. Under the act, the federal government would pay for 90 percent of the cost of construction of Interstate Highways. Each Interstate Highway was required to be a freeway with at least four lanes and no at-grade crossings. The publication in 1955 of the General Location of National System of Interstate Highways , informally known as the Yellow Book , mapped out what became

As one of the components of the National Highway System , Interstate Highways improve the mobility of military troops to and from airports, seaports, rail terminals, and other military bases. Interstate Highways also connect to other roads that are a part of the Strategic Highway Network , a system of roads identified as critical to

2400-589: The Hackensack River into Ridgefield Park , where it passes over the New York, Susquehanna and Western Railway's New Jersey Subdivision line and CSX Transportation 's River Subdivision line before there is an exit for 2nd Street. The freeway briefly passes through Bogota before it continues into Teaneck . In Teaneck, I-80 reaches its eastern terminus at the interchange with the New Jersey Turnpike ( I-95 ). From here, one can head southbound on I-95 on

He recalled that, "The old convoy had started me thinking about good two-lane highways... the wisdom of broader ribbons across our land." Eisenhower also gained an appreciation of the Reichsautobahn system, the first "national" implementation of modern Germany's Autobahn network, as a necessary component of a national defense system while he

2600-611: The National Highway System in the United States . The system extends throughout the contiguous United States and has routes in Hawaii , Alaska , and Puerto Rico . In the 20th century, the United States Congress began funding roadways through the Federal Aid Road Act of 1916 , and started an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921 . In 1926,

2700-527: The Saddle River , eventually crossing it into Lodi . Immediately after, there is a diamond interchange at Riverview Avenue that provides access to Route 4 and Route 17 . Heading southeast, I-80 passes over the New York, Susquehanna and Western Railway Lodi Branch line and comes to an interchange at Route 17, which provides access to US 46 to the south, Route 4 to the north, and various local roads. At this point, I-80 runs between

2800-506: The US Department of Defense . The system has also been used to facilitate evacuations in the face of hurricanes and other natural disasters. An option for maximizing traffic throughput on a highway is to reverse the flow of traffic on one side of a divider so that all lanes become outbound lanes. This procedure, known as contraflow lane reversal , has been employed several times for hurricane evacuations. After public outcry regarding

This numbering system usually holds true even if the local direction of the route does not match the compass directions. Numbers divisible by five are intended to be major arteries among the primary routes, carrying traffic long distances. Primary north–south Interstates increase in number from I-5 between Canada and Mexico along

3000-506: The United States Numbered Highway System 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

Major west–east arterial Interstates increase in number from I-10 between Santa Monica, California , and Jacksonville, Florida , to I-90 between Seattle, Washington , and Boston, Massachusetts , with two exceptions. There are no I-50 and I-60, as routes with those numbers would likely pass through states that currently have US Highways with

At this point, the freeway widens to eight lanes and continues into Totowa , passing near more commercial areas and over the Norfolk Southern Railway railroad line as it comes to an interchange with Minnisink Road ( CR 642 ) that has access to and from the west. A short distance later, there is a westbound exit and eastbound entrance serving Union Boulevard ( Route 62 / CR 646 ). I-80 crosses

3300-576: The Congress Hotel in Chicago. In the plan, Mehren proposed a 50,000-mile (80,000 km) system, consisting of five east–west routes and 10 north–south routes. The system would include two percent of all roads and would pass through every state at a cost of $ 25,000 per mile ($ 16,000/km), providing commercial as well as military transport benefits. In 1919, the US Army sent an expedition across

The next interchange along the road is with Saddle River Road ( CR 79 ) and is a westbound entrance and an eastbound exit accessible from the local lanes. The freeway passes over the New York, Susquehanna and Western Railway line again and turns south along the west bank of

3500-652: The George Washington Bridge, Route 4 and US 46 already provided high-speed corridors, but they were overloaded, and so a new corridor in between, the Bergen–Passaic Expressway, was planned to run from the bridge to Paterson . The planned route west to the Delaware Water Gap was designated in 1956 as Federal Aid Interstate Route 101 by the New Jersey State Highway Department . It first received

I-80 enters Hardwick Township , Warren County , from Pennsylvania on the Delaware Water Gap Toll Bridge over the Delaware River , maintained by the Delaware River Joint Toll Bridge Commission . In addition to carrying I-80, this bridge also carries the Appalachian Trail over the Delaware River. From this point,

3700-576: The I-80 designation. The old alignment of US 611 in Pennsylvania had become US 611 Alt. . By 1966, I-80 had been completed from Netcong to Denville and from Paterson to I-95. By 1969, the section between I-280 in Parsippany and Route 23 in Wayne was finished. Also around this time, US 611 was moved off I-80 and back into Pennsylvania, replacing US 611 Alt. By 1971,

3800-475: The I-82 designation before finally becoming a part of I-80 in 1958. The easternmost section of the route, leading to the bridge, had become part of I-95 . The section of I-80 through the Delaware Water Gap had already opened on December 16, 1953, running from the Delaware Water Gap Toll Bridge to Route 94 at Columbia . This road was signed as a realignment of US 611 from Pennsylvania, later receiving

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

4600-481: 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

There is a westbound exit and eastbound entrance serving both US 46 and Route 53 as the road begins to turn more to the east. I-80 turns south and crosses the Montclair-Boonton Line for a third time before it enters Parsippany . The highway makes a turn east as it comes into an area of business parks, with

5000-406: The choice of routing destroyed many well-established neighborhoods, often intentionally as part of 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

5400-407: 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

5500-567: 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

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

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

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

Now maintained by the New Jersey Department of Transportation , the road makes a sharp turn to the east and comes to a u-turn ramp in both directions that also has access to the Appalachian Trail. The highway heads south again and enters Knowlton Township , where it comes to another set of U-turn ramps that also includes

6700-455: The freeway carries four lanes eastbound and three lanes westbound. Upon coming into Allamuchy , I-80 has six lanes before gaining a fourth eastbound lane as it comes to the exit for CR 517 , providing access to Allamuchy Mountain State Park . Following this, the road runs through densely forested areas of the park, coming to two pairs of rest areas with no facilities in both directions. The eastbound direction becomes three lanes again before

6800-429: 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,

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

7100-554: The highway crosses over the NJ Transit 's Morristown Line / Montclair-Boonton Line and reaches a partial interchange with US 46, which has only a westbound exit and eastbound entrance. The freeway briefly crosses through Netcong and Mount Olive again before continuing into Roxbury , where it comes to a modified cloverleaf interchange . At this interchange, Route 183 heads north into Netcong and US 206 splits from I-80 by heading south. The road continues through wooded areas containing some suburban development as it comes to

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

7300-402: 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

7400-442: The interchange with Landing Road ( CR 631 ), which also provides access to eastbound US 46. The road crosses the NJ Transit line again and parallels it a short distance to the north as it comes into Mount Arlington and reaches the exit for Howard Boulevard ( CR 615 ), serving Mount Arlington Station . I-80 continues back into Roxbury and comes to a westbound truck rest area with the eastbound one being abandoned. After this,

7500-431: 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

7600-484: The local lanes having an eastbound exit and westbound entrance at South Beverwyck Road ( CR 637 ). After this, there is a large interchange with US 46 and the western terminus of I-280 , at which point the local–express lanes end. From this point, I-80 continues east through wooded areas as a six-lane freeway, crossing into Montville , where there is a partial interchange providing access to Hook Mountain Road. After

7700-454: 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

7800-753: 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

7900-400: The median widening before an interchange serving US 202 and Cherry Hill Road ( CR 654 ). The median narrows again before I-80 reaches the interchange with I-287 that also has movements to US 46, Smith Road, and Littleton Road to and from the east. Past I-287, I-80 gains the local–express lanes with a 2-3-3-2 configuration. The road continues past more commercial areas, with

8000-404: 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

8100-509: 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. Scenic viewpoint Many viewpoints are larger, having parking areas , while some (typically on larger highways ) are off

8200-595: The ones that had been built on I-287 , were opened to regular traffic in 1998 due to lack of usage, and the state did not have to repay the federal government the $ 240 million (equivalent to $ 419 million in 2023) to build the lanes. In 1994, the New Jersey Department of Transportation adopted and began using the Rockfall Hazard Rating System for evaluating and ranking highway rock-cut slopes. The segment of I-80 between mileposts 1.0 and 1.4, has been continually characterized as having

8300-561: The original Interstate Highway System was proclaimed complete in 1992, despite deviations from 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

8400-656: 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 ),

8500-411: 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

8600-411: The road completely. Viewing points may also be found on hill or mountain tops or on rocky spurs overlooking a valley and reached via a hiking trail . They may be protected by railings to protect the public or be enhanced by a viewing tower designed to elevate visitors above the surrounding terrain or trees in order to offer panoramic views . Overlooks are frequently found in national parks , and in

8700-502: The road heads farther north of the railroad tracks and briefly passes through Jefferson and Rockaway townships before continuing into Wharton . Here, the freeway has an eastbound exit to North Main Street ( CR 634 ) that provides access to Route 15 before it reaches the interchange with Route 15 proper that lacks an eastbound exit. The highway continues back into Rockaway Township as it widens to eight lanes and comes to

8800-542: The road passes through Byram Township in Sussex County . Upon crossing the Musconetcong River , I-80 enters Mount Olive in Morris County and passes through more woodland with a narrower median. The road comes to a trumpet interchange with US 206 and forms a concurrency with that route as it bypasses Netcong to the south. After turning southeast and passing near suburban business parks,

8900-405: The route increases. After this interchange, the freeway turns east away from the Delaware River and crosses over Paulins Kill before it continues through wooded and hilly areas containing some farms, with the eastbound direction widening from three to four lanes, and the highway median also widens. A scenic overlook of the Delaware Water Gap is located in the westbound direction while a rest area

9000-478: 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

9100-419: 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

9200-503: 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

9300-586: The section between Wayne and Paterson was completed along with the part between US 202 and I-280. A 3.5-mile (5.6 km) section between US 46 in Denville and US 202 in Parsippany–Troy Hills, was opened in September 1973. Also in 1973, the section between US 206 in Netcong and US 46 and Route 94 in Columbia was completed, and the interchange in Columbia was realigned into

9400-631: The state as the Christopher Columbus Highway . A freeway along the I-80 corridor had been planned in 1936 and again in 1955 to provide relief along US 46 between the George Washington Bridge and the Delaware Water Gap . With the establishment of the interstate highway system , the planned freeway, which had been identified in some planning documents as the Bergen–Passaic Expressway (which same name

9500-571: The travel lanes of Route 17 as it continues into Hackensack . Past Route 17, I-80 gains a 3-2-2-3 local–express lane configuration and crosses over the NJ Transit's Pascack Valley Line before passing through industrial parks and runs briefly through South Hackensack . Here, there is an interchange to Green Street before the highway comes into Teterboro . Turning east, the freeway runs through South Hackensack before entering Hackensack, where an exit provides access to Hudson Street ( CR 124 ). The road passes near neighborhoods before crossing

9600-495: The turnpike towards Newark or head northbound towards the George Washington Bridge and New York City . A freeway along the I-80 corridor was first planned in 1936 as a replacement for the cross-state US 46 , running from the George Washington Bridge west to the Delaware Water Gap and Scranton, Pennsylvania . After World War II , New Jersey officials considered the proposal again in 1955. Coming off

9700-440: 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

9800-551: 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

9900-422: 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

10000-547: 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
