America’s Highways for 17 miles along Interstate 81 from mile 42 to exit 59 in Tennessee.
Interstate 81 is a north–south (physically northeast–southwest) Interstate Highway in the eastern part of the United States. Its southern terminus is at I-40 in Dandridge, Tennessee; its northern terminus is on Wellesley Island at the Canadian border, where the Thousand Islands Bridge connects it to Highway 401.
I-81 largely traces the paths created down the length of the Appalachian Mountains through the Great Appalachian Valley by migrating animals, American Indians, and early settlers. It also follows a major corridor for troop movements during the Civil War.
