+ National Highways Low Carbon Bridge Design Competition, Finalist
The purpose of the National Highways Bridge Design Competition was to propose a new suitable low-carbon footbridge, located at the north end of the proposed route for the Lower Thames Crossing (LTC) scheme. Davies Maguire’s design was announced as a runner-up, making it to the top 5 out of over 60 entries.
Working closely with the design team, we were able to develop a multi-span bridge which incorporated low embodied carbon techniques, whilst successfully integrating with the surrounding natural environment.
The main emphasis of the bridge design was to showcase the benefits of adopting timber as an alternative construction material. The longevity of timber, when used correctly, is proven by centuries-old timber bridges across Europe. Glulam girders were supported over piers, spanning 30.0m and 40.0m, with approach spans of 15.0m. A cross-sectional concept was designed, featuring a robust structure shielded by an overhanging, water-draining surface.
We utilised emerging technological innovations, particularly in advanced timber construction, weathering steel and pre-stressed stone, and combined this with a creativity and sensitivity toward the landscape, site, materials and the end users. This presented an innovative, long-lasting, and sustainable structure for the future.
