U.S. Route 1 Bypass (US 1 Byp.) is a 4.3-mile-long (6.9 km) bypass of U.S. Route 1 in Portsmouth, New Hampshire and Kittery, Maine. Most of its north section, northeast of the Portsmouth Traffic Circle where it meets the Blue Star Turnpike (Interstate 95 or I-95) and Spaulding Turnpike, is built to rudimentary freeway standards, with no cross traffic but driveway access. The southern portion is similarly constructed, although there are two four-way intersections with traffic lights just south of the circle and a third at its south end, just before intersecting with US 1.
