STRUCTeam, Apex Composite Structures design, engineer sustainable composite footbridge
The 12.5-meter bridge provides pedestrian access through the village of Newchurch on the Isle of Wight, inspired by a similar footbridge commissioned by Network Rail in 2009.
In early June 2022, STRUCTeam Ltd. (Cowes, U.K.) and Apex Composite Structures (Ryde, U.K.), a bespoke composite manufacturer, have worked in partnership to design and engineer a 12.5-meter footbridge on the Isle of Wight, an island off the south coast of England. The newly installed structure provides pedestrian access through the village of Newchurch, meaning walkers no longer need to navigate a narrow and busy stretch of road.
Newchurch Parish Council commissioned the building of the bridge and were seeking an economical and robust crossing solution for this section of “Norah’s Way” — a dedicated rights of way footpath, opened in 2019 by Norah Boswell’s family in her memory.
STRUCTeam and Apex’s engineers specified lightweight materials and sustainable manufacturing methods wherever possible to enable efficient production, easy transportation and rapid installation of the bridge.
The composite bridge design was pitched against steel and hard wood alternatives. However, these traditional building materials require maintenance and repainting every 25 years. By comparison, it is estimated the composite bridge will need very minimal upkeep and will not need to be replaced for 100 years.
The bridge’s foam core is made from 30,000 reprocessed plastic bottles. George Downer, company director of Apex Composite Structures, remarks. “By selecting plastic bottles over the other options available to us, we have achieved a 33% reduction in CO2 emissions.”

Apex Composite Structures took inspiration from a similar footbridge commissioned by Network Rail (London, U.K.) in 2009 to improve pedestrian safety at dangerous level crossings. In fact, it was Downer’s father, Mark Downer, who designed and built the first prototype bridge for the Network Rail initiative.
STRUCTeam maintains a varied portfolio of clients both locally and around the world. According to Jon Evans, STRUCTeam’s composite design engineer, “Since our formation in 2010, we have delivered bridges, canopies and facades for many high-profile architectural designs. However, it is always a privilege to work on a project closer to home that will directly benefit the community and support other island businesses.”
STRUCTeam has announced other recent developments including support of a wave energy converter.
