'''Interstate&nbsp;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 [[Quebec Route 133|Route 133]]. The eventual completion of [[Autoroute 35]] will lead to a nonstop [[Limited-access road|limited-access highway]] route between Boston and Montreal, following [[Interstate 93|I-93]] south from I-89's terminus. The largest cities directly served by I-89 are [[Concord, New Hampshire|Concord]], the state capital of [[New Hampshire]]; [[Montpelier, Vermont|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 [[Interstate 91|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: [[U.S. Route 4|US Route 4]] (US 4) from [[Enfield, New Hampshire]], to [[Hartford, Vermont]]; [[U.S. Route 2|US 2]] from [[Montpelier, Vermont|Montpelier]] to [[Colchester, Vermont]]; and [[U.S. Route 7|US 7]] from [[Burlington, Vermont|Burlington]] to the Canadian border. US 7 and US 2 overlap each other between Burlington and Colchester.

In [[Chittenden County, Vermont]], [[Interstate 189|I-189]] begins at exit 13 in [[South Burlington, Vermont|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.<ref>{{cite web |url=http://www.champlainparkway.org |publisher=CHA Companies |access-date=March 11, 2016 |date=2010 |title=Project Overview}}</ref> I-189 is the only [[List of auxiliary Interstate Highways|auxiliary route]] of I-89.
