After 120 kilometers, you reach the main interchange on the route, Interstate 89 at White River Junction. I-89 runs from Concord in New Hampshirevia the capital Montpelier to Montreal. Also north of this, I-91 follows the Connecticut River, which also forms the border with New Hampshire. At Wells River one crosses US 302, a main road from Montpelier to Littleton. Near the town of St. Johnsbury, Interstate 93 ends at I-91, which comes from Concord and Boston, and is also a north-south route.
