Interstate 87 (I-87) is a major north–south route in New York State, stretching from the bustling urban core of New York City all the way to the Canadian border. It plays a crucial role in connecting the metropolitan New York area with Albany, the Adirondack Mountains, and Montreal via Quebec Autoroute 15. With a total length of approximately 333 miles, I-87 serves as a vital transportation corridor for commuters, tourists, and commercial traffic alike.
The route begins in the Bronx at the Major Deegan Expressway, where it intersects with I-278 near the Robert F. Kennedy Bridge. As it moves northward, I-87 follows the Hudson River Valley, overlapping with the New York State Thruway from Yonkers to Albany. North of the state capital, the route transitions into the Adirondack Northway—a scenic highway that winds through the forested foothills of the Adirondacks, offering access to outdoor destinations like Lake George, Saratoga Springs, and Lake Placid.
Notable interchanges along I-87 include connections with I-95, I-287, I-84, I-90, and I-787. The highway is especially important for international trade and tourism, as it terminates at the Champlain–St. Bernard de Lacolle Border Crossing, one of the busiest between the U.S. and Canada. This makes I-87 a key component of the CANAMEX Corridor and the broader North American Free Trade network.
