Interstate 89

Interstate 89 (abbreviated I-89) is an interstate highway in the New England region of the United States travelling between Bow, New Hampshire and Highgate Springs, Vermont. 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 major cities of Montreal and Boston. The largest cities directly served by I-89 are Concord, New Hampshire and Burlington, Vermont. I-89 is one of three main Interstate highways whose entire route is located within the New England states, along with Interstate 91 and Interstate 93.

Interstate 89 connects smaller cities and rural areas within New Hampshire and Vermont, and maintains two lanes of traffic in each direction throughout the route. Unlike its neighboring Interstates (91 and 93), it does not intersect any even-numbered Interstates along its route. It does, however, parallel (and interchange multiple times with) portions of three U.S. routes: U.S. Route 4 from Enfield to White River Junction; U.S. Route 2 from Montpelier to Colchester, and U.S. Route 7 from Burlington to the Canadian border.
