United States Highway 2 is an east-west United States highway. US 2 is the designation of two very distinct routes along the northern edges of the country -- but while some routes became discontinuous because of encroaching Interstate highways, US 2 has been split since it was commissioned in the original 1926 highway plan.
The eastern segment of US 2 traverses the northern reaches of the New England states.
As of 2004, the highway's eastern terminus is in Houlton, Maine at the Canadian border. It shares the endpoint with Interstate 95, and the route continues as Provincial Highway 95. Five miles into Canada, this route intersects with Trans-Canada Highway 2. Its western terminus is in Rouses Point, New York, also at the Canadian border. US 2 and U.S. Highway 11 meet, turn north a half mile to the border, and continue as Provincial Highway 223.
As of 2004, Alternate US 2 has an eastern terminus in Houlton, Maine, just two miles from the start of the main line route. It rejoins US 2 in Macwahoc. While the main line of US 2 follows Interstate 95 for a while before heading south, Alternate US 2 veers to the south and east to serve an isolated area of the state.
The highway passes through the following states:
The western segment of US 2 extends from the Upper Peninsula of Michigan across the northern tier of the lower 48 states.
As of 2004, the highway's eastern terminus is in St. Ignace, Michigan at an intersection with Interstate 75. Its western terminus is in Everett, Washington at an intersection with Washington State Route 529 (former U.S. Highway 99). However, signage is unclear between there and the intersection with Interstate 5.
Until 1984, the eastern end of US 2 extended up Interstate 75 to the Canadian border, in Sault Ste. Marie, Michigan.
