The General Sullivan Bridge is a deck truss bridge, with a through truss span to accommodate ship traffic, that formerly carried the roads that now travel over the Little Bay Bridges. The bridge was named for John Sullivan, a Revolutionary War general, Governor of New Hampshire, and delegate to the Continental Congress, who was from nearby Somersworth. Little Bay had previously been spanned by a railroad and automobile bridge, which had been completed in December 1873 and began carrying rail traffic in February 1874; after 60 years of service, it was dismantled in February 1935. Its abutments were located approximately north of the General Sullivan Bridge. Near the Newington-side abutment, the 1873-constructed Newington Railroad Depot still stands.
