Information AboutInterstate 81 |
Interstate 81 (abbreviated '''I-81''') is an Interstate Highway in the eastern part of the United States . Its southern terminus is at Interstate 40 near Dandridge, Tennessee ; its northern terminus is on Wellesley Island (near Fishers Landing, New York ) at the Canadian Border where the Thousand Islands Bridge connects it to Highway 401 , the main freeway leading from Windsor - Detroit and Toronto to Montreal . Interstate 81 largely traces the path of the Appalachian Mountains , often paralleling its older U.S. Highway counterpart, U.S. Route 11 . While mostly rural, it is heavily used as a trucking corridor, often as a bypass of the more urban Interstate 95 to the east. ROUTE DESCRIPTION
