U.S. Route 9 (US 9) is a United States Numbered Highway in the Northeastern U.S., running from Laurel, Delaware, north to Champlain, New York. In Delaware, the route runs a southwest–northeast path through Sussex County. Even though US 9 is signed north–south for the remainder of its route, the segment in Delaware is signed east–west. The highway runs from its western terminus at US 13 in Laurel northeast to the Cape May–Lewes Ferry terminal in Lewes, where the ferry carries the route across the Delaware Bay to North Cape May, New Jersey. US 9 passes through rural areas and serves the communities of Laurel, Georgetown, and Lewes. US 9 intersects Delaware Route 20 (DE 20) in Hardscrabble, US 113 and DE 18/DE 404 in Georgetown, DE 30 in Gravel Hill, DE 5 in Harbeson, and DE 1 at the Five Points intersection in Nassau. US 9 runs concurrent with DE 404 between Georgetown and Five Points and with DE 1 between Five Points and Carpenters Corner.

What is now US 9 in Delaware was originally built as a state highway during the 1920s and designated by 1936 as Delaware Route 28 (DE 28) between Laurel and Georgetown and a part of DE 18 between Georgetown and Lewes. US 9 was extended to Delaware from New Jersey by way of the Cape May–Lewes Ferry in 1974, replacing all of DE 28 and the portion of DE 18 between Georgetown and Five Points, with the route aligned to bypass Lewes. DE 404 was designated concurrent with the portion of US 9 between Georgetown and Five Points by 1987.

Route description

US 9 begins at an intersection with US 13 in the commercial northern part of the town of Laurel, where the road continues west past the terminus of US 9 as Georgetown Road. From the western terminus, the route heads to the northeast on two-lane undivided County Seat Highway. The road leaves Laurel and runs through a mix of farmland and woodland with some homes. The route intersects DE 20 in the community of Hardscrabble, at which point it briefly becomes a divided highway. Past this intersection, US 9 becomes undivided again and continues through rural land, crossing Tyndall Branch and passing to the southeast of the University of Delaware's Carvel Research and Education Center and Sussex Technical High School. Past this, the route heads through the community of Whaleys Corners. Farther northeast, the road reaches the town of Georgetown and intersects US 113/DE 404 Truck in a commercial area. At this point, US 9 Truck heads south along US 113/DE 404 Truck to bypass Georgetown to the south. Following US 113, the route continues northeast on West Market Street through residential areas. US 9 enters downtown Georgetown and intersects DE 18/DE 404 at a traffic circle called The Circle, where the Sussex County Courthouse is located.

At this point, US 9 continues northeast concurrent with DE 404 on East Market Street through the downtown area. The road crosses the Delmarva Central Railroad's Indian River Subdivision line at-grade and runs through residential areas with a few businesses, passing south of the Southern Delaware Tourism Visitors Center. US 9/DE 404 heads east-northeast out of Georgetown and becomes Lewes Georgetown Highway, passing through farmland and woodland with some development. The two routes intersect the eastern terminus of US 9 Truck/DE 404 Truck a short distance east of Georgetown. In the community of Gravel Hill, the road crosses DE 30. Following this intersection, US 9/DE 404 passes through more rural land, reaching a junction with DE 5 near businesses in the community of Harbeson. Past here, the two routes cross an abandoned railroad line at the Cool Spring Road intersection in the community of Cool Spring. Farther east, residential development near the road begins to increase, with the road passing through the community of Belltown. Upon reaching the area of the Five Points intersection in the community of Nassau, US 9/DE 404 runs past homes and businesses, widening into a divided highway and coming to an intersection with DE 1D/DE 23. DE 23 joins US 9/DE 404 for a concurrency on a four-lane divided highway before the road comes to a junction with DE 1. Here, DE 23/DE 404 ends, US 9 Business (US 9 Bus.) continues northeast, and US 9 heads east for a concurrency with DE 1. At this intersection, access from eastbound US 9 to northbound DE 1 is provided by a reverse jughandle.
