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.
Blue Ridge Parkway
The Blue Ridge Parkway is a National Parkway and All-American Road in the United States, noted for its scenic beauty. The parkway, which is America's longest linear park, runs for through 29 Virginia and North Carolina counties, linking Shenandoah National Park to Great Smoky Mountains National Park. It runs mostly along the spine of the Blue Ridge, a major mountain chain that is part of the Appalachian Mountains. Its southern terminus is at U.S. 441 on the boundary between Great Smoky Mountains National Park and the Cherokee Indian Reservation in North Carolina, from which it travels north to Shenandoah National Park in Virginia. The roadway continues through Shenandoah as Skyline Drive, a similar scenic road which is managed by a different National Park Service unit. Both Skyline Drive and the Virginia portion of the Blue Ridge Parkway are part of Virginia State Route 48, though this designation is not signed.
