A 24-hour contraflow system launches on the M6 Thelwall Viaduct on 19 October for bridge joint replacement works. The viaduct carries the M6 over the Manchester Ship Canal and River Mersey in Warrington. A 40mph speed limit will apply in both directions, with four lanes maintained during the day and one northbound lane running on the southbound side of the motorway.
A full overnight closure of the northbound carriageway between junctions 20 and 21 will occur from 10pm to 5am on Tuesday, 20 October, with diversions via the M56, M60 and M62. The first phase of works will continue until March 2027, focusing on the northbound side. A southbound contraflow will be introduced in spring 2027, with southbound joint replacement works running until December 2027. Final resurfacing and road marking will be carried out under overnight lane closures in winter 2027-28.
National Highways said replacing the bridge joints is 'essential to reduce the risk of unexpected closures, keep the bridge working safely and effectively, and minimise disruption for road users over the long term'.
