Sutton Weaver Swing Bridge
Sutton Weaver, near Frodsham, Cheshire
Carries the A56 over the River Weaver.
Opened in 1926. Designed by Colonel John Arthur Saner. Built by Joseph Parks and Son of Northwich, replacing an earlier swing bridge built in 1872.
Two-thirds of the weight of the steelwork is accommodated by a float, leaving the remainder to be supported by 114 rollers.
The bridge is turned by an electric motor acting on a wire rope. The rope can be seen in photos 2 & 3.

The bridge recently underwent major refurbishment, completed in 2014.
