at Winnington, near Northwich

Also known as Winnington Turn Bridge.

See British Listed Buildings entry, here.

It is one of five large swing bridges taking roads across the River Weaver.

Designed by John Arthur Saner to replace an older, smaller bridge which was in poor condition.

A full description of the bridge, with illustrations, was provided in The Engineer in 1909[1]. Some extracts: The bridge weighs about 150 tons, the girders 108 ft long, and the clear width of the waterway 55 ft. The pivot was unusual: a double row Hoffmann ball bearing, having 40 balls 2.25" diameter, the assembly being supported by a ball and socket arrangement. There are six turntable rollers, which only come into play in the event of excessive movement. Swinging was effected by a wire rope whose capstan was driven by a Mather and Platt 30 HP motor. A 5 HP Mather and Platt motor worked the locking wedges. The components, apart from the proprietory items mentioned, were made by the Weaver Navigation workshops.
