Allerton Steel has fabricated the main beams for Edgecott Road Overbridge, Buckinghamshire
Posted on 14 November 2024
The 112m Weathering steel bridge will carry Edgcott Road across the new high-speed railway and an existing freight line, which runs parallel for five miles between the Bucks Railway Centre near Quainton and the village of Calvert.
Nine beams were fabricated with flanges of 40 & 65mm and webs of 28 & 40mm steel beams using submerged arc welding process. The complete fabrications weighed over 600T.
All beams were lifted in place by a Terex CC3800-1 crawler crane.
