Interstate 89

North End
South End


Interstate 89 is a scenic highway serving the states of Vermont and New Hampshire. The freeway joins the capital cities of Montpelier and Concord as part of its northwestern route to Lake Champlain from southern New Hampshire. Continuing northward from Burlington, Interstate 89 transitions into Quebec Provincial Route 133, which leads north to Autoroute 35 for Montreal, Canada. Future construction will provide a seamless connection to Autoroute 35.

Parallel U.S. Routes

Interstate 89 briefly parallels U.S. 4 as it crosses from New Hampshire into Vermont before turning northward along an independent alignment to Montpelier. U.S. 2 accompanies the freeway west from Montpelier to Burlington, where U.S. 7 ties in northward to Milton and the Lake Champlain Islands. U.S. 2 turns west to South Hero while U.S. 7 stays adjacent to I-89 to the Canadian border at Highgate Springs.


In Vermont, Interstate 89 was built in stages through the 1960s. Specific opening dates for certain segments are as follows1:

  • Montpelier to Middlesex (6.287 miles) – November 21, 1960
  • Middlesex to Waterbury (5.106 miles) – December 31, 1960
  • Waterbury to Bolton (7.049 miles) – November 20, 1961
  • South Burlington to Winooski (3.388 miles) – November 29, 1962
  • Winooski to Colchester (1.184 miles) – November 1, 1963
  • Richmond to South Burlington (8.723 miles) – November 6, 1963
  • Bolton to Richmond (6.745 miles) – October 30, 1964
  • Colchester (6.486 miles) – November 1964
  • Swanton to Highgate (5.538 miles) – 1965

Interstate 89 opened initially in New Hampshire between Warner and New London in November 1967. Completion within the state followed a year later.2

North Carolina

NCDOT previously submitted the Interstate 89 designation for the U.S. 64 freeway corridor between Raleigh and Williamston and U.S. 17 leading northeast from Williamston to the Virginia state line at the AASHTO Special Committee on U.S. Route Numbering meeting on May 24, 20163. AASHTO ultimately approved Interstate 87 for the new corridor.4
