Little Bay Bridge

The Little Bay Bridge is a twin-span girder bridge that carries a concurrency of U.S. Route 4, NH Route 16, and the Spaulding Turnpike across the mouth of Little Bay, where it meets the Piscataqua River, between the city of Dover and the town of Newington in New Hampshire.

The first span, which is now the southbound span, was opened in 1966. The second span was opened in 1984.

The two spans were built to replace an older one, named the General Sullivan Bridge, which was built in 1935 and is still standing though closed to traffic.
