U.S. Route 9 In New York

U.S. Route 9 (US 9) is a part of the U.S. Highway System that runs from Laurel, Delaware, to Champlain, New York. In New York, US 9 extends 325.01 miles (523.05 km) from the George Washington Bridge in Manhattan to an interchange with Interstate 87 (I-87) just south of the Canada–United States border in the town of Champlain. US 9 is the longest north–south U.S. Highway in New York; additionally, the portion of US 9 in New York accounts for more than half of the highway's total length.

The highway's passage through the state offers a diverse sample of New York to a traveler, taking in busy urban neighborhoods, suburban strips and forested wilderness. It is Broadway in Upper Manhattan, the Bronx and much of Westchester. It uses parts of the old Albany Post Road in the Hudson Valley, where it passes the historic homes of a U.S. President and Gilded Age heir. It passes the center of New York political power in downtown Albany, and the patrician grandeur of Saratoga Springs. It penetrates into the deep recesses of the Adirondack Park and runs along the shore of Lake Champlain, where it is part of the All-American Road known as the Lakes to Locks Passage.

US 9 spawns more letter-suffixed state highways than any other route in New York, including the longest, 143-mile (230 km) New York State Route 9N (NY 9N). Outside of the cities it passes through, it is a mostly a two-lane road, save for two expressway segments in the mid-Hudson region. For much of its southern half it follows the Hudson River closely; in the north it tracks I-87, the Adirondack Northway.
