The new Destructor Bridge will connect the revitalised area of Bath Western Riverside with the A4 Upper Bristol Road over the River Avon in the historic town of Bath, UK.
Claimed to be "one of the most important regeneration projects in the UK" by the client, the Bath Western Riverside revitalisation includes the upgrade of the Destructor Bridge. The previously existing bridge, built in 1870s, was no longer suitable to serve the needs of the community, nor was it capable of carrying modern traffic loads. It was determined that a replacement bridge would be the most economical and feasible option. Flint & Neill, as part of the Design & Build team, was selected to provide the design of the new bridge, as well as the concrete pile foundations and concrete abutments.
The replacement structure is an elegant 48 metre long asymmetric steel tied arch bridge with two box girders. It will accommodate a two-lane highway for vehicles, a wider pedestrian walkway, and a cycleway, and will provide improved access to the development area. The steel arch supports a composite deck through flat plate hangers. The prefabricated units were welded on-site in 24 pieces.
The 400 tonne bridge was finally launched successfully this past week. At the back of the bridge was a self-propelled modular transporter, while the other side was supported by rollers on temporary towers. The team will now begin a two week operation to remove the temporary structures before the bridge is lowered into its final bearing position.
Video of the launch will be available within the next few weeks, but additional footage of the project's progress can be viewed here.
