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.
Mount Vernon, Texas
Bankhead Highway Visitor Center – The Bankhead Highway, which opened in 1919 and ran from Washington D.C. to San Diego, was the nation’s first all-weather transcontinental highway. It passes through Franklin County and serves as Mount Vernon's Main Street and follows an early Indian trading route known as the Choctaw Trail. By 1930 it was renumbered as U. S. No. 1 and was called "The Broadway of America." The Bankhead Highway Route was changed in 1937 and follows present U. S. Hwy 67. 
The Visitor Center is one fourth mile west of U.S. Highway 37 on CR NW 1017. Just follow Main Street to the west past Highway 37. The Visitor Center includes the Lowry Pavilion, which is available to rent for special outdoor occasions, and the Dupree Park Nature Preserve and Nature Trail, a mile and a half walk through the property with special marked stations for bird sightings. Though the property gates are locked at off hours, a pedestrian gate allows admittance for individual use from dawn until dusk. A printed trail guide is available in the Visitor Center.
