U.S. Route 1 (US 1) in the U.S. state of Maine is a major north–south section of the United States Numbered Highway System, serving the eastern part of the state. It parallels the Atlantic Ocean from New Hampshire north through Portland, Brunswick, and Belfast to Calais, and then the St. Croix River and the rest of the Canada–United States border via Houlton to Fort Kent. The portion along the ocean, known as the Coastal Route, provides a scenic alternate to Interstate 95 (I-95).
