Swing bridge over Brunel's South Entrance Lock, Bristol
This swing bridge was built in 1875-6 by IK Brunel from wrought-iron with a timber-floored deck. It is a copy of Brunel's original bridge which was moved to the North Entrance Dock in 1873. The bridges cross Bristol's Floating Harbour. The harbour was created by putting locks on the Rivers Frome and Avon to allow Bristol to develop as a port. Swing bridges were needed so that ships with tall masts could pass through.
