Graham has completed the installation of the new bridge across the River Chelmer in Chelmsford, Essex.
The two single-span bowstring arches, weighing 110t, were lifted into position by a 500t crawler crane with the aid of a 280t super lift for counterbalance.
The arches were manufactured offsite in eight separate pieces, welded on location and fitted with stainless steel tensioning bars to allow them to maintain their shape.
The 50m pedestrian and road bridge is made from corten steel, which is a deep red colour, chosen to reflect the industrial history of the site.
Graham’s project manager, Karl Lomas, said: “The successful installation of the arches marks an exciting and significant moment on the project, which is making good progress thanks to the team’s hard work and a successful collaboration between Graham, Chelmsford City Council and engineer Buro Happold.
“Now that work on the main span has been completed, the team will move on to the next stage of the build, continuing reinforced concrete works and finishing the bridge deck for completion next year.”
