Interstate 81 is an 854.89-mile (1,375.81 km) long north south Interstate Highway, stretching from Dandridge, Tennessee to Fisher's Landing, New York at the US/Canadian border. In the state of Pennsylvania, I-81 runs for 232.63 miles (374.38 km) from the Maryland state line near Chambersburg to the New York state line near Hallstead and is called the American Legion Memorial Highway. I-81 enters Pennsylvania at the Maryland state line about 13 miles (21 km) south of Chambersburg. In Chambersburg at mile marker 16, it meets with a major highway; U.S. Route 30 (the Chambersburg Pike to Gettysburg). About a mile north of Carlisle at exit 52, it meets with U.S. Route 11 which takes passengers to the Pennsylvania Turnpike/ Interstate 76, since I-81 has no direct interchange with I-76.
