Interstate 80 (I-80) is an east–west transcontinental freeway that crosses the United States from San Francisco, California, to Teaneck, New Jersey, in the New York metropolitan area. The highway was designated in 1956 as one of the original routes of the Interstate Highway System; its final segment was opened in 1986. The second-longest Interstate Highway in the United States after I-90, it runs through many major cities, including Oakland, Sacramento, Reno, Salt Lake City, Omaha, Des Moines, and Toledo and passes within 10 miles (16 km) of Chicago, Cleveland, and New York City.
I-80 is the Interstate Highway that most closely approximates the route of the historic Lincoln Highway, the first road across the United States. The highway roughly traces other historically significant travel routes in the Western United States: the Oregon Trail across Wyoming and Nebraska, the California Trail across most of Nevada and California, the first transcontinental airmail route, and the route of the first transcontinental railroad, except for the vicinity of the Great Salt Lake. From near Chicago east to near Youngstown, Ohio, I-80 is a toll road, containing most of both the Indiana Toll Road and the Ohio Turnpike. I-80 runs concurrently with I-90 from near Portage, Indiana, to Elyria, Ohio. In Pennsylvania, I-80 is known as the Keystone Shortway, a non-tolled freeway that crosses rural north-central portions of the state on the way to New Jersey and New York City.
