The UK's Environment Agency has announced that the installation of a new 16m-long footbridge has been completed over the entrance to Twyford Marina at Yalding in Kent, England.  

This project was part of the Environment Agency's navigation capital investment programme, which used new technology for the installation of the bridge. 

The new footbridge is a segment of the Medway Valley Walk, aimed at enhancing pedestrian access while improving boat entry to the marina. 

It was constructed from fibre-reinforced polymer (FRP), a material recycled from old fishing nets.  

The ramps on either side of the bridge were designed in block form, allowing for easy assembly and eliminating the need for mortar in most cases. 

This block system also negates the necessity for reinforced concrete walls. 

The bridge deck itself was fabricated in the Netherlands and weighs approximately 3.5 tonnes. After the addition of handrails in Nottinghamshire, UK, the deck was transported by road to Yalding. 

The last segment was transported by barge along the River Medway. Upon arrival, it was hoisted into position by a crane. 

The bridge has now been opened to the public. 

Environment Agency Kent navigation manager Jason Adams said: “The 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’s carbon net-zero target.” 

Additional work, including the installation of permanent handrails and the finalisation of the path surface on the ramps, is scheduled for later this year to replace the temporary handrails currently in place.
