About: Interstate 89

Interstate 89 (I-89) is an Interstate Highway in the New England region of the United States traveling from Bow, New Hampshire, to the Canadian border between Highgate Springs, Vermont, and Saint-Armand, Quebec. As with all odd-numbered primary Interstates, I-89 is signed as a north–south highway. However, it follows a primarily northwest-to-southeast path. The route forms a substantial part of the main connection between the cities of Montreal and Boston. In Quebec, the route continues as Route 133. The eventual completion of Autoroute 35 from Montreal will lead to a nonstop limited-access highway route between the two cities, following I-93 south from I-89's terminus. The largest cities directly served by I-89 are Concord, the state capital of New Hampshire; Montpelier, the state capital
