U.S. Route 11 or U.S. Highway 11 (US 11) is a major north–south (while physically generally northeast-southwest) United States highway extending 1,645 miles (2,647 km) across the eastern United States. The southern terminus of the route is at U.S. Route 90 in the Bayou Sauvage National Wildlife Refuge in eastern New Orleans, Louisiana. The northern terminus is at the Rouses Point–Lacolle 223 Border Crossing in Rouses Point, New York. The route continues across the border into Canada as Quebec Route 223. US 11, created in 1926, maintains most of its original route. The route north of Knoxville, Tennessee, follows a route similar to Interstate 81 (I-81).
