The viaduct, which is made from pre-stressed concrete, was opened in 1961, and is grade II listed.

[2][3] The viaduct straddles the valley of the River Went, with the village of Wentbridge to the west, and a nature reserve immediately to the east.

[5][6] To alleviate these problems, the Wentbridge bypass, including a new bridge over the valley, was approved in 1959.

[7] Construction of the viaduct required the use of 120 miles (190 km) of scaffolding, and 170,000 scaffolding fittings, all of which was required to withstand a wind force of 90 miles per hour (140 km/h) and support a weight of 8,200 tonnes (9,000 tons).

[13] In 1959, the bridge was costed at £682,000 (equivalent to £20,042,000 in 2023), but because of some extra works, including a two-lane bridge carrying the Went Edge Road over the southern end of Wentbridge Viaduct, the final price was £803,000 (equivalent to £22,577,000 in 2023).
