Somerleyton Swing Bridge
Lowestoft, Norfolk
associated engineer
Not known
date  1905
era  Modern  |  category  Bridge  |  reference  TM474967
ICE reference number  HEW 745
One of two similar swing bridges, the other being Reedham Swing Bridge (TG442017). They are constructed from wrought iron, brick, cast steel and timber and were built to replace the single track bridges that carried the railway between Norwich and Lowestoft over the Rivers Yare and Waveney.
Each bridge rests on two end piers and a central pivot pier made of brick supported by timber piles. This pier is 27ft 6in in diameter and supports the 10in diameter central pivots when the bridge is fixed for railway traffic.
The three wrought iron girders that bear the live load are 139ft long, and rotate on 16in diameter cast steel wheels. The load of the open bridge is borne by two truss girders.
