Broadway is a road in the U.S. state of New York. Broadway runs from the south at State Street at Bowling Green for 13 mi (20.9 km) through the borough of Manhattan, over the Broadway Bridge, and 2 mi (3.2 km) through the Bronx, exiting north from New York City to run an additional 18 mi (29.0 km) through the Westchester County municipalities of Yonkers, Hastings-On-Hudson, Dobbs Ferry, Irvington, Tarrytown, and Sleepy Hollow, after which the road continues, but is no longer called "Broadway". The latter portion of Broadway comprises a portion of U.S. Route 9.

U.S. Route 9 (US 9) is a north–south United States Numbered Highway in the states of Delaware, New Jersey, and New York in the Northeastern United States. It is one of only two U.S. Highways with a ferry connection ; the other is US 10. US 9 is signed east–west in Delaware and north–south on the rest of its route. The southern terminus of the route is in Laurel, Delaware, at an intersection with US 13, while the highway's northern terminus is at a junction with Interstate 87 (I-87) in Champlain, New York, where the old roadway continues north as the unsigned New York State Route 971B (NY 971B), which ends in a cul-de-sac just short of the Canadian border.
