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 Canada–United States 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 major 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 will lead to a nonstop limited-access highway route between Boston and Montreal, 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 of Vermont; and Burlington, Vermont. I-89 is one of three main Interstate highways whose route is located entirely within New England, along with I-91 and I-93 (both of which also have their northernmost pavement in Vermont).
I-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, it does not intersect any even-numbered Interstates along its route. It does, however, parallel (and intersect multiple times with) portions of three US Routes: US Route 4 (US 4) from Enfield, New Hampshire, to Hartford, Vermont; US 2 from Montpelier to Colchester, Vermont; and US 7 from Burlington to the Canadian border. US 7 and US 2 overlap each other between Burlington and Colchester.
In Chittenden County, Vermont, I-189 begins at exit 13 in South Burlington. The Champlain Parkway, which will be one travel lane in each direction and have at-grade crossings, is being constructed between the current terminus of I-189 at US 7 and Burlington's South End as a link toward downtown Burlington. I-189 is the only auxiliary route of I-89.
I-89 runs for about 61 miles (98 km) in the state of New Hampshire and is the major freeway corridor through the western part of the state. Despite being signed as a north–south freeway, its first eight miles (13 km) actually run east–west before shifting to the northwest. The two major population centers along I-89's length in New Hampshire are Concord, at its southern terminus, and Lebanon, on the Vermont state line. Mileage signs along I-89 in each direction consistently list one of the two cities. Also located along I-89 in New Hampshire are the towns of Grantham, New London, and Warner.
Starting at an interchange with I-93 and New Hampshire Route 3A (NH 3A) in the town of Bow, just south of the New Hampshire capital city of Concord, the highway runs a northwest path through the Dartmouth–Lake Sunapee Region. One exit directly serves Concord (exit 2) before the highway enters the neighboring town of Hopkinton. East–west NH 11 joins I-89 at exit 11 and runs concurrently with it for about three miles (4.8 km) before departing at exit 12. At exit 13 in Grantham, NH 10 enters I-89, and the pair of highways form another concurrency, this one for about 15 miles (24 km).
Southeast of Lebanon, signs for exit 15 display the name "Montcalm", while exit 16 directs travelers to "Purmort". Neither place name existed at the time of construction of the Interstate. Exits 15 and 16 were built to access portions of the town of Enfield that were otherwise cut off by the new highway. The names were chosen by Enfield's selectpeople in 1960; the Purmorts were a prominent local family in the early history of Enfield, and Montcalm was a nearby settlement that had once had its own school and post office. While the Purmort exit does allow access to the state road network (specifically to US 4 via Eastman Hill Road), the Montcalm exit provides access to an otherwise isolated community; every public road from the exit is a dead-end, and leaving the Montcalm area by car requires getting back on I-89 at exit 15. However, a bicycle path parallels I-89 between exits 14 and 16 along the path of Old Route 10, allowing foot or bicycle access to the community.
The highway continues northwest, passing through Lebanon, in which the Dartmouth–Hitchcock Medical Center is located. A few miles north of this point is Dartmouth College. US 4 parallels I-89 through Lebanon. Exits 17 through 20 serve the city of Lebanon and are passed in quick succession. At exit 19, northbound NH 10 separates from I-89 and joins westbound US 4 to pass through West Lebanon. The final exit in New Hampshire is exit 20, providing access to West Lebanon's large retail district along NH 12A. Just after this interchange, the highway crosses the Connecticut River and enters Vermont, where it remains for the rest of its run northwest to the Canadian border.
I-89 is one of Vermont's most important roads, as it is the only Interstate Highway to directly serve both Vermont's capital city (Montpelier) and largest city (Burlington). Other important cities and towns located along I-89 are Barre, Waterbury, and St. Albans. Williston, which has become Burlington's big-box retail center (and one of the fastest-growing towns in the state) over the past decade, also has an interchange along I-89.
