THE PLANNING AND DESIGN OF THE BOBBEJAANS RIVER BRIDGE

A description is given of the steps taken during the development of the design of a large reinforced concrete arch bridge, of its analysis and of the structure as it was eventually built. In the solution adopted a 16 m wide deck is designed to carry two 317 m wide traffic lanes plus two 3.8 m wide shoulders. This configuration can be later changed -should traffic require it -to four 3.6 m wide lanes, two in each direction, separated by a 0.6 m wide New Jersey type barrier. The bridge described was finished in 1983 and carries National Freeway N2 over the Bobbejaans River, South Africa. (TRRL)
