The A1 between Leeming and Barton is being upgraded from dual carriageway to three-lane motorway. Numerous structures need to be replaced or extended.
From its Darlington facility, Cleveland Bridge fabricated steelwork for bridges, which range between 80 tonnes and 400 tonnes, and supervised their erection and installation. The scheme’s largest bridge was the 86.5-metre Kneeton Lane Bridge, near Scotch Corner, which at 398 tonnes was also the heaviest.
Cleveland Bridge also supported the widening of existing structures, including the Agricola Bridge that carries the A1 across the River Swale, just south of Brompton on Swale. This required an additional 170 tonnes of steel to widen the existing bridge by seven metres either side with a total span of 57 metres.
Chris Droogan, managing director of Cleveland Bridge UK, said: “The widening of the A1 in North Yorkshire is an essential part of improving the transport infrastructure of the North and we are very pleased to have played a key part in its delivery. This was a highly time-focused project involving the production and installation of around 1,600 tonnes of steel. Working closely with our client we have efficiently completed the delivery of the bridges, which is a significant milestone in this major civil engineering project.”
