New River Medway bridge constructed with low carbon materials
Old recycled fishing nets provide fibre-reinforced polymer. Lower maintenance needed than for conventional materials. Improved river access to Twyford Marina.
What a catch?! Old fishing nets put to good use to create a brand new bridge across the River Medway in Kent
皇冠体育app Environment Agency has used innovative technology to install a new 16-metre long bridge over the entrance to Twyford Marina at Yalding, Kent. This is part of its navigation capital investment programme.
皇冠体育app bridge body and deck are made from fibre-reinforced polymer (FRP), recycled from old fishing nets. Ramps on either side of the bridge were in block form and could be laid by hand, mostly without the use of mortar, similar to Lego bricks. 皇冠体育app block system also removes the need for reinforced concrete walls.聽
皇冠体育app bridge deck was built in the Netherlands. Weighing in at 3.5 tonnes, it was shipped to Nottinghamshire where handrails were added, then was hauled by road to Yalding. 皇冠体育app final leg was by barge along the River Medway, where it was lifted into position by crane.
Easy does it! 皇冠体育app Medway's newest bridge is lowered into place. Its fibre-reinforced polymer structure won't need as much maintenance as conventional bridges
皇冠体育app new footbridge forms part of the Medway Valley Walk and provides passage over the river entrance of Twyford Marina and significantly improves boat access to the marina.
With the finishing touches completed, the bridge is now open to the public. Permanent handrails and path surface to install to the ramps will be carried out in the autumn to replace the current temporary handrails.
Jason Adams, Environment Agency navigation manager for Kent, said,
皇冠体育app bridge is both light and strong, meaning we could install the structure in a difficult location. With its lighter weight we could also reduce the size of the supporting foundations required giving a lower carbon footprint.
Overall, it will require less maintenance compared to a bridge made of traditional materials and enables a substantial carbon saving, helping Medway navigation to contribute to the Government鈥檚 carbon net zero target.
