Structurally, the bridge comprises two sets of approach spans, each of which has three spans, either side of the central main lifting span. Each span comprises two riveted longitudinal steel deck girders, supporting riveted cross girders, which in turn support a reinforced concrete slab deck. Each set of three spans consists of two simply supported end spans which continue as cantilevers approximately 1/5 span into the middle span. The central 3/5 span sections are simply supported drop in spans supported by halving joints. The main span is a structurally independent lifting span. The bearings are inset from the end lifting beams. Spans 1, 3, 5 and 7 are c/c of bearings. Spans 2 and 6 are , with halving joints from both end and a suspended span of . The central lifting span, Span 4, is c/c of bearings, with cantilevers of either end to the lifting cross girders. The approach spans have cross girders, spaced apart, while the lifting girder features cross girders spaced at intervals of .
