ASSET MULTIPLATE UNDERPASS RESTRENGTHENING - SALFORD

SALFORD, GREATER MANCHESTER

PROJECT OVERVIEW

As part of the Railway Bridge No.7 Reconstruction Scheme, Salford City Council required rehabilitation of an existing bridge deck along with maintenance to the cycle route access and usage. The chosen solution for Railway Bridge No.7 was to reline the underpass utilising asset MultiPlate MP200, with a span of 7.78m, a 4.25m rise, and a length of 110m.

Railway Bridge No.7 carries the A580 East Lancashire Road over the disused Eccles, Tyldesley and Wigan railway line based in Salford, Greater Manchester.

PROBLEM SOLVED

Although the cycle route was temporarily closed during relining, traffic routes were maintained throughout the installation with only intermittent route deviations required during the pumping of foam concrete. As a result of restrengthening the now-redundant existing structure, the asset MultiPlate corrugated solution with a design life of 120 years, now bears the full load of the road above.

ESG

Deliveries were condensed due to less transportation of material to site, thanks to the lightweight nature of asset MultiPlate corrugated steel. The uninterrupted traffic flowing above the structure also enabled social connectivity along the A580 and beyond.

Following successful installation, cyclists were able to use the National Cycle Network Route 55 as originally intended. Through bridge rehabilitation and relining utilising asset MultiPlate, structural integrity was maintained, maximising on-site safety.
