Two Railway Bridges of Composite Construction. Discussion on the paper by C. F. Bonnett AMlStructE

Mr. F. Turton (Member) said that he was interested in the history of these bridges. In the Lune Bridge they had an excellent example of a problem which the bridge engineers concerned had at some time or another met in three different ways. The designer of the original bridge had decided to use framed arches in timber; what his reasons had been they did not know but it seemed a rather elegant solution to a problem quite different from the one met on the present occasion, since the original designer had not had to deal with railway traffic. He had probably had to allow for river traffic from the harbour which then existed at Lancaster, upstream of the bridge, and for the passage of sailing vessels, or possibly steam vessels, with tall masts.
