Redhayes bridge lifted into position in Devon

A new cyclist and pedestrian bridge in Devon has been lifted into position spanning the M5.

The Redhayes structure is situated near Exeter and has cost £3.75 million to construct, with funding provided by Devon County Council.

It is the first bridge over a UK motorway to be wholly designed using the Eurocodes standards, which are now specified for all Highways Agency and Network Rail civil engineering projects.

Designed by Parsons Brinkerhoff's Director of Engineering, Dr Steve Denton, the bridge is 100 metres long and has a twin-arch bowstring structure.

Dr Denton said: "The lift has gone very smoothly and we are absolutely delighted with the result. It will be an iconic landmark for Exeter, marking the gateway to the city."

Weighing 220 tonnes, its placing was delayed by a day following high winds, but it now provides a linked to a new science park, which is being built close to the city.

An article in New Civil Engineer by Mr Denton about the M5 crossing noted the withdrawal of British Standards to be replaced by the Eurocodes in April 2010 had a significant effect on bridge designers.
