U.S. Route 2 (US 2) is a part of the United States Numbered Highway System that is split into two segments. Its eastern segment runs from Rouses Point, New York, to Houlton, Maine. In Vermont, US 2 extends 150.518 miles (242.235 km) from the New York state line in Alburgh to the New Hampshire state line in Guildhall. West of Vermont, US 2 continues into New York for another 0.87 miles (1.40 km) to an intersection with US 11 in Rouses Point. US 2 passes through the cities of Burlington and Montpelier as it traverses the state. The highway parallels Interstate 89 (I-89) between these two cities. The Burlington to Montpelier route was first laid out as a toll road in the early 19th century. It was later incorporated into the transcontinental auto trail known as the Theodore Roosevelt International Highway in 1919 before being designated as part of US 2 in 1926.
Although the portion of the road from Alburgh to Burlington follows a north–south alignment, US 2 is continuously signed east (heading south during this portion) and west (heading north) to match its overall alignment, making it the longest east–west signed route in the state. At a nearly 460-mile (740 km) overall length, US 2 is also the longest highway of any designation (Interstate, U.S. Route, or state highway) that enters the state of Vermont.
