Polymer bridge for St Austell railway crossing

Network Rail's first self-supporting fibre reinforced polymer (FRP) bridge was lifted above the main Paddington-Penzance line at St Austell, Cornwall over the weekend.
Designed by Parsons Brinckerhoff, made by Pipex in Plymouth and installed by Edmund Nuttall for Network Rail, the bridge is one of a number of pilot structures commissioned to test FRP, which could eventually be used in footbridges, platforms, stairs and walkways.

This bridge was built in three sections – two 2t, 6m side spans and a central 14m span weighing just 5t.

It is expected to be virtually maintenance free.
