Description
This unusual design of bridge would be a great addon for the Lincolnshire/Humber area, more info below.
Keadby Bridge, more formally known as the King George V Bridge, crosses the River Trent near Althorpe and Keadby in Lincolnshire.
Its 50-metre (163 ft) electrically powered bascule (lifting span) was one of the first of its type in Britain and, when built, was the largest in Europe. Designed by James Ball and C A Rowlandson and built by contractors Sir William Arrol & Co., it has three main spans and two approach spans. The eastern main span was the one that lifted. The Scherzer bascule rolled and rotated on counterbalance. It was electrically powered, originally by a large storage battery fed by petrol-driven generators housed in the engine room beneath the east approach span.[4] This was later modified to mains electricity.
The bridge was controlled from a wooden signal cabin, mounted by the north-east side of the lifting (east) span. It was fitted out with a 28-lever frame of British Pneumatic Railway Signal Company design.
The bridge has not been lifted since 1956. The bridge was widened and the headroom increased in 1960 and the bascule was fixed in position.[5] At the same time, the signal cabin was removed from the bridge structure. The tracks on the railway were fixed in place.
