This paper describes the FW de Klerk bridge across the Vaal River at Vereeniging, South Africa. It has an innovative design, which was interfaced with the construction operations, to provide an effective and elegant solution subject to site constraints and construction methods. As a result, the length of the construction contract was reduced. The bridge has a total length of 232 m and its five-span structure minimises pier foundations in the difficult working conditions in the Vaal River, by using two free cantilevers with hinges to form the main 100 m span; the cantilevers were cast on site. Its deck width is 15.9 m for most of the length, but widens to 20 m at one end. It uses a specialised concrete caisson for the river pier. Its construction was economical and used precast balustrade units and a specialised formwork carriage for the construction of the free cantilever deck. Considerable geotechnical problems were experienced during the construction of the foundations, and special measures were taken to handle them. The concrete caissons and bridge deck spans are described in some detail. (TRRL)
