Engineers have won a prestigious award for their work on strengthening a historic bridge in Shropshire.
Coalport Bridge carries the Broseley to Coalport road over the River Severn. The listed structure and scheduled ancient monument was built in 1818.
It was reopened in March after 11 months for the £1.4m strengthening work. It is thought to be the oldest cast-iron bridge carrying traffic.
The award went to Shropshire County Council and Telford and Wrekin Council.
It was presented to the project team, and was one of only two given nationally by the Institution of Civil Engineers judging panel this year.
It was to recognise "excellence and innovation in conservation".
Traffic was previously restricted to a single two-tonne vehicle at a time. Barriers were added to restrict the size of vehicles, but the restriction was frequently violated.
English Heritage was consulted throughout the scheme , and scheduled monument consents were obtained for the work.
The strengthening work involved launching a temporary bridge over the top of the existing bridge to carry the weight of the construction work.
Shropshire County Council's Principal Bridge Engineer, John Williams, said: "Although it is appreciated that the road closure necessary to carry out the work caused inconvenience to the community, the bridge will now be able to safely remain open to traffic in the long term."
