The Atlantic Highway

U.S. Route 1 is a major north-south national highway that serves the East Coast of the United States. Originally called the Quebec–Miami International Highway in 1911, it was renamed the Atlantic Highway in 1915. When the New England road marking system was established in 1922, the Atlantic Highway within New England was designated as Route 1. If you have ever traveled sections of Route 1 you may be interested in its detailed, and quite confusing, history.
