Winterbrook Bridge, also known asWallingford By-pass Bridge, was built in 1993 as part of a by-pass aroundWallingford, Oxfordshire, relieving the single-laneWallingford Bridge. It forms part of theA4130, connectingWinterbrook, at the north end ofCholsey, just south of Wallingford, on the west bank toMongewell on the east bank. It crosses theThames on the reach betweenCleeve Lock andBenson Lock. The 55-metre (180 ft) three-span bridge is built of steel plate girders with a reinforced concrete deck slab and glass fibre reinforced plastic cladding on the underside.[2]
During the construction, the remains of a lateBronze Age settlement on a formereyot were investigated on the west bank of the Thames.[3] The bridge was designed so as not to disturb the archaeological site. Close to the east bank, nearMongewell, the construction work allowed examination of theSouth OxfordshireGrim's Ditch, the long earthwork followed by theRidgeway Path, and showed it to be lateIron Age/earlyRoman.
