Built as a toll bridge in 1773, the sandstone bridge spans 23m. The Grade II listed bridge links Barnard Castle near Durham with the A66. Heavy commercial vehicles regularly cross the bridge.
'They managed to do away with unsightly timber supports by stitching the stone together using steel ties. The bridge now looks exactly as it did in 1773. The judges were particularly impressed with this project because of the tastefulness of the renovation,' said Paxton.
David Newbegin of Durham County Council designed the strengthening. The 155,000 contract was carried out by PBS Construction.
