This article briefly describes the construction of a modern new bridge over the River Thames at Staines to duplicate an existing portland stone and brick bridge spaced 3.3 M apart. The two bridges will carry both the existing A30 and future M25 traffic. Due for completion in September, 1979, construction involves the fabrication of a set of four post tensioned concrete frames spaced out to support a deck of the same width and span (33.8 M by 125 M) as the old bridge. Photographs illustrate the techniques employed to precast all the major structural items on site - on both sides of the river, and to position them in place. Information is provided on concrete pouring techniques and the method employed for post-tensioning the frames. White concrete, using white cement and white coarse and fine aggregate from Ballidon, Derbyshire, is being used throughout the bridge superstructure; the finished concrete being bush-hammered to resemble the portland stone of the old bridge. /TRRL/
