Interstate 95, the main Interstate Highway on the east coast of the United States, cuts through the Seacoast Region of New Hampshire. The majority of it, from the Massachusetts border to the Portsmouth Circle in Portsmouth, is the 14.29-mile-long (23.00 km)Blue Star Turnpike or New Hampshire Turnpike, a toll road maintained by the New Hampshire Department of Transportation Bureau of Turnpikes. The final piece in Portsmouth splits from the Turnpike south of the circle, running 2.42 miles (3.89 km) to the Piscataqua River Bridge, a steel arch bridge, towards Maine and the Maine Turnpike. In its short length through New Hampshire, Interstate 95 traverses six municipalities - Seabrook, Hampton Falls, Hampton, North Hampton, Greenland, and Portsmouth.
