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.
Interstate 95 in Pennsylvania
Interstate 95 (I-95) is an Interstate highway running from Miami, Florida, north to Houlton, Maine. In the U.S. state of Pennsylvania, it runs from the Delaware state line near Marcus Hook to the Delaware River–Turnpike Toll Bridge at the New Jersey state line. From the Delaware state line to exit 40, the route is known by many as the Delaware Expressway, but is officially named the Vietnam Veterans Memorial Highway. North(east) of exit 40, I-95 runs along the easternmost portion of the Pennsylvania Turnpike. I-95 parallels its namesake Delaware River for its entire route through the city of Philadelphia and its suburbs. It is a major route through the city and the metropolitan Delaware Valley, providing access to locally important landmarks such as Philadelphia International Airport, the South Philadelphia Sports Complex, Talen Energy Stadium, Penn's Landing, and Philadelphia Mills. Of the 15 states that Interstate 95 runs through, Pennsylvania is the only one that does not border the Atlantic Ocean.
