U.S. Route 9 (US 9) is a north–south United States highway in the states of Delaware, New Jersey, and New York in the United States. It is one of only two U.S. Highways with a ferry connection (the Cape May – Lewes Ferry, between Lewes, Delaware, and 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/western terminus of the route is in Laurel, Delaware at an intersection with U.S. Route 13, while the highway's northern terminus is at a junction with Interstate 87 in Champlain, New York, where the roadway continues north as the unsigned NY 971B, which ends in a cul-de-sac just short of the Canadian border.
