U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
Maine State Route 101
SR 101 begins in the south at an intersection with US 1 in Kittery, just northeast of its intersection with SR 236, where US 1 Bypass meets its northern end. Near this intersection is the exits 2 and 3 interchanges from the Maine Turnpike. The route heads northwest, intersecting local roads as it passes east of the town of Eliot. SR 101 intersects with SR 236 and enters the southern tip of South Berwick. The highway continues a short distance northwest before crossing the Piscataqua River into Dover, New Hampshire. Upon crossing into New Hampshire, SR 101 ends and the road continues as unnumbered Gulf Road. Motorists following this road west will soon come across signage leading to New Hampshire Route 4 towards downtown Dover. No advance signage exists in the reverse direction, with Gulf Road simply transitioning to SR 101 upon crossing into Maine.
