Introduction

In October 2012, the composites world celebrated a historic milestone in Dawlish, United Kingdom. The world’s first Grade II listed FRP bridge replaced the Grade II listed Dawlish footbridge in the coastal scenic county of Devon.

In the year 1937, the original structure was constructed and was deteriorated beyond repair because of salt spray-induced corrosion along with the harsh marine environment of the region. The replacement of this bridge was a challenge as it was one of the 500,000 man-made structures protected by the UK’s architectural and historic listing.

Solution

Network Rail engineers presented alternative solutions in an attempt to refurbish the corroding girders, roof, protective paintwork and rotting timber decking, but replacement by Pipex px FRP fabrication was concluded to be the ideal solution. The Dawlish footbridge was designed and engineered by Tony Gee and Partners and Optima Projects, with installation completed by Bam Nutall.

Portions of the bridge were prefabricated with Pipex px to ensure quick installation and precise testing performance while ensuring the right replication in design of the original 1930's Grade II listed steel bridge. Strongwell's EXTREN® plate was used for light fixture points and heat deflection, SAFPLATE was used for covering flooring, COMPOSOLITE was used as a main floor structure showcasing its advanced toggle system and kick plates as fascia panels on the roof side. On completion, the 60-foot bridge length weighed in at only one-third of its 15-ton steel counterpart and at the same time was more capable of withstanding a 13-ton load. This is the first composite bridge at a mainline station in the UK and is the second FRP footbridge to ever be installed. It has been designed with a life expectancy of 120 years with no maintenance requirements.
