U.S. Route 1 In New York

U.S. Route 1 (US 1) is a part of the U.S. Highway System that runs from Key West, Florida, to the Canada–United States border at Fort Kent, Maine. In the U.S. state of New York, US 1 extends 21.69 miles (34.91 km) from the George Washington Bridge in Manhattan to the Connecticut state line at Port Chester. It closely parallels Interstate 95 (I-95) for much of its course, and does not serve as a major trunk route within the state. It does not overlap with any other roads besides I-95 and (briefly) US 9, and few other state highways intersect it.

It passes through a variety of different terrain within the city and Westchester County, from the Cross Bronx Expressway to several important surface roads in the northwestern Bronx and then the main street of the Westchester suburbs along Long Island Sound. In many of the latter communities, it begins to intermittently follows the route of the historic Boston Post Road, and often still carries that name.
