Kings Arms Pedestrian Swing Bridge, Exeter

The previous bridge dated back to 1972. The structure had deteriorated to the point where repair was no longer viable and hence a design that was visually similar was developed which included retaining the design of the historic stays. Minimal changes were allowed to the historic quay sides and hence the replacement structure was designed to fit within these constraints whilst still being manually operable.

The replacement structure is a single span steel composite deck. The structure is constructed from steel beams with a steel plate deck. The structural design was carried out to BS EN 1993 and mechanical components to BS 2573-2.
The design was developed from concept through to fully detailed fabrication drawings for the structure and all mechanical elements.
