INNOVATIVE 'PLASTIC' BRIDGE TECHNOLOGY WELCOMED BY HIGHWAYS AGENCY
HIGHWAYS AGENCY News Release (HA/NW/072/06) issued by The Government News Network on 1 June 2006
A new lightweight 'plastic' bridge has been installed over the M6 motorway in Lancashire allowing rapid construction and reduced disruption road users.
The innovative fibre−reinforced polymer (FRP) bridge is two−thirds the weight of the old bridge, but stronger and offers cost savings through reduced maintenance in the future.
FRP is the first major new construction material since the introduction of reinforced concrete 100 years ago.
This is the first time the Highways Agency has used FRP for road bridge construction on the motorway network, but the technique has been used on footbridges,
The new bridge will replace the 40−year−old farm access bridge at Mount Pleasant near Garstang in a £2 million project.
Although only for farm and equestrian centre access, the new bridge has been built to carry vehicles up to 40 tonnes.
The benefits of the technique are:
* Lightweight bridge allows rapid installation reducing disruption during construction.
* New bridge has a superior strength/weight ratio to steel or concrete.
* Non−corrosive properties with water and salt, thus reducing future maintenance.
* Reduced future maintenance means road users will see fewer road works and experience less disruption.
* Reduces whole life costs
* Demonstrates the Highways Agency's commitment to using innovative techniques.
* The Highways Agency by investing in new technology hopes to help stimulate further innovation which will led to cheaper and more durable bridges
Highways Agency project manager Phil Davies said:
"The use of innovative techniques is essential to ensure that we have a road network fit for modern day road users. Using FRP means this new bridge will be two−thirds the weight, but twice as strong as using conventional materials.
"The advantage for motorists is that there is less disruption because construction time has been reduced and less maintenance will be needed in the future and demonstrates the Highway Agency's commitment to investing in new technology."
