The Little Bay Bridge, or Little Bay Bridges, are a pair of four-lane girder bridges that carry 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. As of August 2019, the bridges carry seven motor vehicle lanes with four shoulders, and one non-motorized multi-use path while the General Sullivan Bridge is closed. Capt. John F. Rowe Bridge The first Little Bay Bridge, which consists of a pair of two-lane spans, is officially the Capt. John F. Rowe Bridge. Its first span was opened in 1966 and originally carried northbound traffic, with southbound traffic utilizing the parallel General Sullivan Bridge, which had been completed in 1934. The second span of the Rowe bridge was opened in 1984. At that time, the General Sullivan Bridge was permanently closed to vehicle traffic, southbound traffic was moved to the 1966 span of the Rowe bridge, and the 1984 span of the Rowe bridge was used for northbound traffic. A second Little Bay Bridge was completed in 2013, with traffic shifted to it so the Rowe bridge could be closed for renovations. Renovations were completed in November 2015, although the Rowe bridge remained closed for several years due to significant realignment work on the nearby U.S. Route 4 interchange. Northbound traffic returned to the Rowe bridge in December 2018. Northbound traffic may eventually be expanded to use four lanes of the Rowe bridge; the third northbound lane was opened on May 23, 2019, and a temporary non-motorized multi-use path on the northbound shoulder was opened in August 2019. Ruth L. Griffin Bridge The second Little Bay Bridge, with a capacity of four traffic lanes, is officially the Ruth L. Griffin Bridge, named for a 20-year member of the Executive Council of New Hampshire. It was built to temporarily ease traffic congestion across the Rowe bridge, and was completed in November 2013. It is physically located between the Rowe bridge and the General Sullivan Bridge. Once the Griffin bridge was completed, all traffic from the Rowe bridge was moved to it, so the Rowe bridge could be closed for renovations. The Griffin bridge continued to handle all traffic for several years due to realignment of the nearby U.S. Route 4 interchange. Northbound traffic returned to the Rowe
