Steel replacement bridge for major Cheshire road junction

Posted on by in News

Approximately 293t of structural steelwork has been used to construct the 68m-long M56/A533 replacement bridge in Cheshire.

Situated between junctions 11 and 12 of the M56, the bridge will replace an older structure to form a new vital link across the motorway for traffic going to Runcorn and Northwich.

The bridge is a two-span weathering steel structure, which will carry a two-lane carriageway and a combined footpath/cycleway.

According to National Highways, the replacement of this bridge will ensure an increased life span of over 120 years for road users, maintaining safety in the long term.

Working on behalf of the Amey/Sir Robert McAlpine JV, Briton Fabricators initially trial erected the entire steel structure at its fabrication yard, prior to delivering it to an assembly point close to its final location.

“By undertaking a trial assembly, we ensured the steelwork could be assembled onsite without any unforeseen challenges,” says Briton Fabricators Commercial Director Dean Morcom.

“We then delivered the steel structure and installed it onto the client’s trestle system, where the deck slab is now being constructed in readiness for the complete bridge to be moved by SPMTs to its final location.”

The bridge is due to be open by summer 2023.
