This bridge forms part of a grade-separated half trumpet interchange constructed at a traffic congested junction in Mecca. The principles governing the general design of the structure are outlined, various design features being considered using computer-plotted perspectives. Reasons are given for the choice of in situ cast concrete construction, with the prestressing of the central suspended span. Skew toothed sliding plate joints, and bearings were used to accommodate movements, the temperature ranging from 0 deg C to 50 deg C. Due to a proliferation of services, raft foundations were constructed instead of piles, the bridge design loadings being as recommended by the UK dept of the environment. Details are included of concrete supply, mix design and strength specifications, also of reinforcement and prestressing steels. Information is presented on the labour force and equipment employed in the project, and a bar chart shows the programme of construction over twelve months. (TRRL)
