Built for the North Eastern Railway and supervised by Harrison, this swing bridge carries the railway line from Leeds to Hull over the River Ouse. It was part of the original east coast main line, rerouted to avoid the Selby Coalfield in 1983.
The bridge has five spans, some of which cross roads. One fixed span of 110ft 6in crosses the river, as does the swing span of 130ft. A small span cross a footpath at the northern end.
Two main girders make up the spans. Both tracks of the rail line sit on full length cross girders. The substructure is supported on cylinders that go down 78ft to sandstone.
The swing span moves on 24 cast steel rollers, 2ft 6in in diameter. Its main girders are 130ft long and are at 26ft centres. The pivot point is not in the middle -- the two arms are 45ft and 85ft long. Because they are unequal, a 92 ton balance weight was needed at the north end.
There was an earlier opening brdge at this site. It was a cast iron two-leaf trunnion bascule bridge (1839) that formed part of the Hull & Selby Railway.
