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 Cape May–Lewes Ferry, between Lewes, Delaware, and North Cape May, New Jersey); 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 of US 13,[a] while the highway's northern terminus is at a interchange with I-87 in Champlain, New York, where the old roadway continues north as the unsigned New York State Route 971B (NY 971B) (0.46 m/0.74 km), which ends in a cul-de-sac just short of the Canadian border.
