The construction of a precast bridge, which can be built in 60 hours, is described. The system features the exclusive use of pre-cast units and a new method of forming bridge abutments using steel sheet and "h" piles compositely. Previously welded Unissen piles were used. The abutments consisted of 9.5m long sections of Larssen 10a and 10b/20 sheet piling welded to 16m long sections of universal beams, which carry bridge loads in end bearing and provide lateral 'support' to the sheets. These retain the ground by spanning between the main piles. The system is sensitive to ground conditions and would be unsuitable for boulder clay or similar unpredictable materials. Composite piles were successfully used for the railway bridge construction at Shrivenham, which will carry high speed trains. /TRRL/
