Provincetown is the eastern terminus of U.S. Route 6, both in the state and in the nation. Although the terminus is directed east officially, geographically speaking, the road, having curved around Cape Cod, is facing west-southwest at the point, and is marked only by its junction with Route 6A. The state-controlled portion ends with a "" sign as the road enters the Cape Cod National Seashore, after which the road is under federal maintenance. Route 6A passes through the town as well, mostly following Bradford Street (whereas US 6 originally followed Commercial Street before the bypass was built and Commercial Street was switched to one-way westbound), and ending just south of the Herring Cove Beach.
