Interstate 80 (I-80) is an east–west transcontinental freeway that crosses the United States from downtown San Francisco, California, to Teaneck, New Jersey, in the New York metropolitan area. The highway was designated in 1956 as one of the original routes of the Interstate Highway System; its final segment was opened in 1986. The second-longest Interstate Highway in the United States after I-90, it runs through many major cities, including Oakland, Sacramento, Reno, Salt Lake City, Omaha, Des Moines, and Toledo and passes within 10 miles (16 km) of Chicago, Cleveland, and New York City.
Interstate 75 (I-75) is a major north–south Interstate Highway in the Great Lakes and Southeastern regions of the United States. As with most Interstates that end in 5, it is a major cross-country, north–south route, traveling from State Road 826 and SR 924 on the Hialeah–Miami Lakes border to Sault Ste. Marie, Michigan, at the Canadian border. It is the second-longest north–south Interstate Highway and the seventh-longest Interstate Highway overall.
Interstate 71 (I-71) is a north–south Interstate Highway in the midwestern and southeastern regions of the United States.

I-71 runs concurrently with I-75 from a point about 20 miles (32 km) south of Cincinnati, Ohio, into Downtown Cincinnati. While most odd numbered Interstates run north–south, I-71 takes more of a northeast–southwest course, with some east–west sections, and is mainly a regional route serving Kentucky and Ohio. It links I-80 and I-90 to I-70 and ultimately links to I-40. Major metropolitan areas served by I-71 include Louisville, Cincinnati, Columbus, and Cleveland.
The Ohio Department of Transportation (ODOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes.
