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 17
U.S. Route 17 or U.S. Highway 17 (abbreviation U.S. 17, US 17, also known as the Coastal Highway) is a north–south United States highway. The highway spans the southeastern United States and is close to the Atlantic Coast for much of its length. The highway's southern terminus is at Punta Gorda, Florida, at an intersection with US 41. Traveling north, US 17 joins up with US 50 in Paris, Virginia, and the northern terminus of US 17 is in downtown Winchester, Virginia. This is also the point at which the portion of US 50 called the Northwestern Turnpike begins.
