Wallingford Bridge is a medieval road bridge over the River Thames in England which connects Wallingford and Crowmarsh Gifford, Oxfordshire (Wallingford was historically in Berkshire until 1974 reorganization). It crosses the Thames on the reach between Cleeve Lock and Benson Lock. The bridge is 900 feet long and has 22 arches but most traffic now crosses Winterbrook Bridge, built as part of the by-pass to the south of the town in 1993.
