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 9W
U.S. Route 9W (US 9W) is a north–south U.S. Highway in the states of New Jersey and New York. It begins in Fort Lee, New Jersey, as Fletcher Avenue crosses the US 1–9, US 46, and the Interstate 95 (I-95) approaches to the George Washington Bridge, and heads north up the west side of the Hudson River to US 9 in Albany, New York. As its "W" suffix indicates, US 9W is a westerly alternate route of US 9 between the two locations. US 9W directly serves three cities—Newburgh, Kingston, and Albany—and enters the vicinity of several others. As the route heads north, it connects to several highways of regional importance, including I-84, US 209, New York State Route 23 (NY 23), and US 20. Much of US 9W parallels the New York State Thruway and NY 32; additionally, the latter overlaps with US 9W in four different locations.
