Interstate 91 marker

Interstate 91 (I-91) is an Interstate Highway in the New England region of the United States. It provides the primary north–south thoroughfare in the western part of New England. The Interstate's southern end is in New Haven, Connecticut at Interstate 95 and its northern end is at Derby Line, Vermont, a village in the town of Derby, at the Canadian border, where it continues past the Derby Line-Rock Island Border Crossing as Autoroute 55. I-91 is the longest of three Interstate highways whose entire route is located within the New England states (the other two being I-89 and I-93), and is also the only primary (two-digit) Interstate Highway in New England to intersect all five of the others that run through the region. The largest cities along its route are Springfield, Massachusetts, Hartford, Connecticut, and New Haven, Connecticut, in order from north to south.

I-91 is 290 miles (470 km) long and travels nearly straight north and south: 58 miles (93 km) in Connecticut, 55 miles (89 km) in Massachusetts, and 177 miles (285 km) in Vermont. I-91 parallels U.S. Route 5 (US 5) for all of its length, and many of the exits along I-91 provide direct or indirect access to the older highway. Much of the route of I-91 follows the Connecticut River, traveling from Hartford, Connecticut, northward to St. Johnsbury, Vermont.
