Interstate 80
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 except in the Great Salt Lake area, the entire route of the First Transcontinental Railroad. From near Chicago east to near Youngstown, Ohio, I-80 is a toll road, containing the majority 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.
U.S. Route 80 in Alabama
U.S. Route 80 (US 80) also known as the Dixie Overland Highway, is a major U.S. Highway in the American state of Alabama. The Alabama Department of Transportation internally designated the majority of US 80 throughout the state as State Route 8, save for parts of the route through Selma and near the Mississippi border. Serving as the main east to west highway through Alabama's Black Belt region, US 80 is well known for its role in the events surrounding the Selma to Montgomery marches in 1965, being the route taken by the demonstrators between the two cities as well as being the site of Bloody Sunday. The highway was also once a major transcontinental highway once reaching from Savannah, Georgia to San Diego, California but has since been truncated to Dallas, Texas due to largely being replaced by the Interstate Highway System.
