Winthorpe Bridge is a concrete box girder bridge, carrying the A1 road over the River Trent in Winthorpe, Nottinghamshire, England.
The contracts for the bridge were awarded on 20 March 1962 for £495,695, and construction began on 16 July that year. The 6-mile (9.7 km) bypass was to cost £3,250,000. It was opened on 27 July 1964, by Ernest Marples.
The bridge was constructed by the Danish bridge-builder Christiani & Nielsen. [2] Another Danish civil engineering company Bierrum built the nearby cooling towers, along the River Trent to the north. The Newark bypass was built by Robert McGregor & Sons who would have laid the concrete pavement on the bridge. The north-bound surface had the concrete pavement laid in forty days, with three concrete-batching sites along the bypass preparing the concrete.
The bridge was Grade II* listed on 29 May 1998. [1]
The bridge crosses the River Trent in Winthorpe, Nottinghamshire, which is the third-longest river in England, at 185 miles (298 km). [3] It is a reinforced-concrete bridge made out of nine box girders. [4]
