Interstate 80 (I-80) is the second-longest Interstate Highway in the United States (after I-90). It connects downtown San Francisco, California, to Teaneck, New Jersey (a suburb of New York City). I-80 is the interstate that most closely approximates the route of the Lincoln Highway, the first auto trail to cross the country. The highway roughly traces other historically significant travel corridors in the Western United States: the Oregon Trail across Wyoming and Nebraska, the California Trail through most of Nevada and California, and except for the vicinity of the Great Salt Lake, the entire route of the First Transcontinental Railroad.

The highway from near Chicago, Illinois, east to near Youngstown, Ohio, is a toll road—the ticketed portion of the Indiana Toll Road and the majority of the Ohio Turnpike. At Youngstown, I-80 leaves the toll road alignment, which continues toward Pittsburgh and Philadelphia, in favor of the Keystone Shortway, a shortcut across northern Pennsylvania built as part of a new corridor for I-80. The toll route to Philadelphia, was originally designated as Interstate 80S, but it was renumbered Interstate 76.

I-80 intersects I-90 near Elyria, Ohio, and they share a route west all the way to Portage, Indiana, where I-90 splits off but I-80 then runs concurrently with I-94 until the Chicago suburb of South Holland, Illinois. I-80 then runs concurrently with I-294 until Markham, Illinois.

California

Interstate 80 begins at an interchange with U.S. Route 101 in San Francisco and heads northeast through Oakland, Vallejo, Sacramento, and the Sierra Nevada mountains before crossing into Nevada.

A portion of the route through Pinole, California involved the experimental transplantation of the rare species Santa Cruz tarweed in the right-of-way.

Nevada

In the state of Nevada, Interstate 80 runs northeast from the Lake Tahoe region near Reno to Battle Mountain. At Battle Mountain, it turns east to the salt flats of Utah via Elko. In Nevada, I-80 is routed along the Truckee and Humboldt rivers.

The stretch of I-80 through Nevada is largely desolate and mountainous. Services are limited compared to I-80 in other states.

Utah

After crossing Utah's western border, I-80 crosses the desolate Bonneville Salt Flats west of the Great Salt Lake. The longest stretch between exits on an Interstate Highway is located between Wendover and Knolls, with 37.1 miles (60.1 km) between those exits. This portion of I-80, crossing the Great Salt Desert, is extremely flat and straight, dotted with large warning signs about driver fatigue and drowsiness.

East of the salt flats, I-80 passes through Salt Lake City, where it merges with I-15 for three miles (5 km) before entering the Wasatch Mountains east of the city. It ascends Parley's Canyon and passes within a few miles of Park City as it follows a route through the mountains towards Wyoming.

The route of the Utah section of I-80 is defined at Utah Code Annotated § 72-4-113(10).[3]

Wyoming

In the state of Wyoming, I-80 reaches its maximum elevation of 8,640 feet (2,633 m) above sea level between Cheyenne and Laramie, Wyoming. Farther west in Wyoming, the interstate passes through the dry Red Desert and over the Continental Divide. In a way, the highway crosses the Divide twice, since two ridges of the Rocky Mountains split in Wyoming, forming the Great Divide Basin - from which no surface water escapes.

Nebraska

I-80 enters Nebraska west of Bushnell. The western portion of I-80 in Nebraska runs very close to the state of Colorado, without entering the state; the intersection of Interstate 76 and I-80 is visible from the Colorado-Nebraska state line. From its intersection with I-76 to Grand Island, I-80 lies in the valley of the South Platte and Platte Rivers. The longest straight stretch of interstate anywhere in the system is the approximately 72 miles (116 km) of I-80 occurring between Exit 318 in the Grand Island area and milemarker 390 near Lincoln. Along this length, the road does not vary from an ideally straight line by more than a few yards. After Lincoln, I-80 turns northeast towards Omaha. It then crosses the Missouri River in Omaha to go into Iowa.

Part of Interstate 80 in Nebraska is marked as a Blue Star Memorial Highway.

Iowa

In the state of Iowa, Interstate 80 runs from the I-80 bridge over the Missouri River where it intersects with I-29 and runs east to the Quad Cities and the Fred Schwengel Memorial Bridge over the Mississippi River. It is the main east–west arterial freeway through south-central Iowa, and the main east–west Interstate in the state.

In Iowa I-80 serves the cities of Council Bluffs, Des Moines, Iowa City, and the Iowa portion of the Quad Cities—including Davenport and Bettendorf.

Illinois

In the state of Illinois, I-80 runs from the Fred Schwengel Memorial Bridge across the Mississippi River south to an intersection with I-74. It then runs east across north-central Illinois just north of the Illinois River to Joliet. I-80 continues east and joins I-94 just before entering Indiana.

Indiana

In the state of Indiana, I-80 runs concurrent with another Interstate Highway for its entire length. It runs with I-94 on the Borman Expressway before joining I-90 to Ohio on the Indiana Toll Road.

The portion of I-80 between La Porte, Indiana and Toledo, Ohio runs (with I-90) within ten miles (16 km) of the Michigan state line. From the State Route 9 and I-80 intersection, the sign marking the Indiana-Michigan state line is visible. At another point in northern Indiana, I-80 comes within about 200 yards (meters) from the Michigan border.[4]

Ohio

In the state of Ohio, I-80 enters with I-90 from the Indiana Toll Road and immediately becomes the "James W. Shocknessy Ohio Turnpike", more commonly referred to as simply the Ohio Turnpike. The two Interstates cross rural northwest Ohio and run just south of the metropolitan area of Toledo. In Rossford, Ohio it intersects with Interstate 75 in an area known as the Crossroads of America. This intersection is one of the largest intersections of two Interstate Highways in the United States.

In Elyria Township, just west of Cleveland, I-90 splits from I-80 and runs northeast as a freeway. I-80 runs east-southeast through the southern suburbs of Cleveland and retains the Ohio Turnpike designation. Just northwest of Youngstown, the Ohio Turnpike continues southeast onto Interstate 76, while I-80 runs east to the north of Youngstown, entering Pennsylvania south of Sharon, Pennsylvania.

Pennsylvania

In the state of Pennsylvania, I-80 is the main east–west Interstate-standard highway through central Pennsylvania. It runs from the Ohio state line near Sharon to the Delaware Water Gap Toll Bridge over the Delaware River,and is called the Confair Memorial Highway.

I-80 serves no major metropolitan areas in Pennsylvania directly. A spur from I-80 (I-180) runs to Williamsport, while another (I-380) runs to Scranton. I-80 intersects I-476 in the Pocono Mountains which connects with Scranton, Wilkes-Barre, Allentown and Philadelphia. I-80 intersects I-79 in Western Pennsylvania which connects with Erie (about 75 miles (121 km) to the north) and Pittsburgh (about 55 miles (89 km) to the south). Interstate 80's highest point (east of the Mississippi) is also located in Pennsylvania, near Exit 111 near Penfield, in Clearfield County.

In 2007, the Pennsylvania Turnpike Commission, combined with state legislature Act No. 44, initiated plans to enact a tolling system on the entire span of I-80 throughout the Commonwealth of Pennsylvania. On October 15, 2007, PennDOT and the Pennsylvania Turnpike Commission signed a 50-year lease agreement, which will allow the Commission to maintain and, eventually, toll I-80.[5] However, such a toll has not been accepted by the Federal Highway Administration.[6]

New Jersey

The eastern end of I-80 in New Jersey

The portion of 80 that goes through New Jersey is called the Bergen-Passaic Expressway.[7]

I-80 does not go all the way to New York City via the George Washington Bridge. Its designated end (as per signage and NJDOT documents) is 4.3 miles (6.9 km)[8] short of New York City in Teaneck, New Jersey. There, signs designate the end of I-80 and the beginning of I-95 (a part of the New Jersey Turnpike).

That mileage markers beyond the end appear to follow as if they were part of I-80 is a coincidence; they match what would have been the correct mileage markers of I-95 had the Somerset Freeway been built.

One section of I-80 running from Netcong to Denville was constructed in 1958. It is one of the oldest sections of Interstate highway in the United States.

Interstate 80 is the second-longest Interstate highway in the United States, after Interstate 90. It shares a route with I-90 from Portage (Indiana) to Elyria.

Route description

Ohio

In Ohio, I-80 is designated as the Ohio Turnpike. In the western half of the state, it is co-signed with I-90. It goes just south of Toledo, around where it intersects with Interstate 75 in one of the largest intersections of two interstate highways in the United States. It splits off from I-90 just west of Cleveland, and goes a bit southeast, heading to the cities of Akron and Youngstown. Just before the Pennsylvania border, it crosses paths with Interstate 76 east and I-80's path becomes I-76, and vice versa.

Major cities

Some major cities along or near the path of Interstate 80 are:

  • Cleveland, Ohio - The second-largest city on Ohio, on the southern shore of Lake Erie.
  • Youngstown, Ohio - Mid-sized industrial city just west of the Pennsylvania border.
