A650 Bingley Relief Road - South Bog Viaduct

The A650 Bingley Relief Road, UK, was completed in December 2003. It is located in the River Aire Valley and required construction of more than 26 structures including two viaducts. The ground conditions are characterised by thick deposits of glacial sands and gravels with kettle holes filled with peat and silt deposits. The South Bog is a site of special scientific interest (SSSI), which also contains the Nidd Aqueduct water pipes. The design of the South Bog viaduct is described. The final solution was to use precast concrete T-beams with an arched profile to the beam web. The structure was 197m in length with a series of 12m spans and a 24m span over the Nidd Aqueduct. Steel tubular piles with a special detail at the pile head were used. This consisted of a concrete plug into which a short steel universal column section was cast. The in-situ plug gave a level platform on which the precast pile caps could be landed. The precast pile caps were lifted in two sections. Once in place, the piers were completed by an in situ concrete pour creating a low-level plinth forming a platform for the precast T-beam units. Details are given of the construction process.
