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.
Delaware
One major branch of the U.S. Interstate Highway System, Interstate 95 (I-95), crosses Delaware southwest-to-northeast across New Castle County. In addition to I-95, there are six U.S. highways that serve Delaware: U.S. Route 9 (US 9), US 13, US 40, US 113, US 202, and US 301. There are also several state highways that cross the state of Delaware; a few of them include Delaware Route 1 (DE 1), DE 9, and DE 404. US 13 and DE 1 are primary north-south highways connecting Wilmington and Pennsylvania with Maryland, with DE 1 serving as the main route between Wilmington and the Delaware beaches. DE 9 is a north-south highway connecting Dover and Wilmington via a scenic route along the Delaware Bay. US 40, is a primary east-west route, connecting Maryland with New Jersey. DE 404 is another primary east-west highway connecting the Chesapeake Bay Bridge in Maryland with the Delaware beaches. The state also operates two toll highways, the Delaware Turnpike, which is I-95, between Maryland and New Castle and the Korean War Veterans Memorial Highway, which is DE 1, between Wilmington and Dover.
