NC 400 is the shortest of all the North Carolina State Highways. It is approximately 1/2 mile long and is entirely within the town of Manteo, North Carolina. The route traverses from its western terminus at U.S. Highway 64 (not bypass) to the Elizabeth II ship (State Historic Site) docked on Shallowback Bay. All the NC 400 signs have brown recreational backgrounds. The route is split among two one-way streets: one going east and the other going west.
