Greenwich Reach Swing Bridge
Galliard Homes, Raymond Brown Construction Ltd
In Partnership with
Cowi (Flint & Neill), Moxon Architects
The project, which had been in the pipeline for many years, was developed in conjunction with Moxon Architects and Cowi (formally known as Flint & Neill).
Eadon were the Mechanical and electrical consultants for the bridge and were responsible for producing the exemplar design for the operating equipment as well as CE Marking the project to the Machinery Directive. Eadon’s engineers worked on several different aspects of the 50 metre crossing, specifically those associated with the movement and control of the bridge.
The deck, supported by a mast and suspension cables, is mounted to a slewing bearing which is located beneath the deck at the location of the mast. The slewing bearing has integral gear teeth which are driven by four pinons coupled to four electric gear motors.
With an opening time of approximately 150 seconds the bridge design needed to be kept simple and hence reliable.
The Greenwich Reach Bridge has gone on to win several awards including winner of the pedestrian bridge category in the 2015 IStructE Structural Awards.
