It forms part of the A4130, connecting Winterbrook, at the north end of Cholsey, just south of Wallingford, on the west bank to Mongewell on the east bank.

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 late Bronze Age settlement on a former eyot were investigated on the west bank of the Thames.

Close to the east bank, near Mongewell, the construction work allowed examination of the South Oxfordshire Grim's Ditch, the long earthwork followed by the Ridgeway Path, and showed it to be late Iron Age/early Roman.
