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.
Kennedy Expressway
The John F. Kennedy Expressway is a freeway in metropolitan Chicago, Illinois, in the United States that travels northwest from the neighborhood of West Loop to O'Hare International Airport. The highway is in memory of the 35th U.S. President, John F. Kennedy, and conforms to the Chicago-area convention of using the term "Expressway" for an Interstate Highway without tolls. The Interstate 90 (I-90) portion of the Kennedy is a part of the much longer I-90 (which runs from Boston, Massachusetts to Seattle, Washington). The Kennedy's official endpoints are the Circle Interchange with Interstate 290 (Eisenhower Expressway/Congress Parkway) and the Dan Ryan Expressway (also I-90/94) at the east end, and the O'Hare Airport terminals at the west end. The Interstate 190 portion of the Kennedy is long and is meant to serve airport traffic. Interstate 90 picks up the Kennedy designation and runs a further , before joining with I-94 for the final .
