Traffic hold-ups warning as repair work closes Thelwall Viaduct


TWO full overnight closures of the M6 southbound carriageway at Thelwall Viaduct near Warrington will take place next week.
Drivers can also expect congestion during the day on Saturday and Sunday June 18 and 19 as two of the four lanes will be closed to traffic
National Highways will be carrying out permanent repairs to a bridge joint on the viaduct next week.
In April, damage to the bridge joint required lane and slip road closures for emergency repairs along the southbound carriageway just beyond the entry slip road at junction 21. National Highways is returning to the bridge next weekend to install a new bridge joint and complete a permanent repair.
Bridge joints are mechanisms in the carriageway which allow the bridge deck to expand and contract safely with changes in the weather.
Work to install the new bridge joint, which straddles lanes two and three of the southbound carriageway, will be done between two full overnight closures of the carriageway for installation and removal of traffic management with the following timetable:
• 9pm Friday June 17 to 6am Saturday June 18 – full closure of the southbound carriageway between junction 21a at Croft Interchange and junction 20 at Lymm Services for the installation of traffic management;
• 6am Saturday June 18 to 9pm Sunday June 19 – permanent repairs to the joint taking place with two lanes running along the southbound carriageway past the roadworks;
• 9pm Sunday June 19 to 6am Monday June 20 – full closure of the southbound carriageway between junction 21a and junction 20 for the removal of the traffic management and re-opening the carriageway to normal four lane running.
During the overnight closures there will be no access to the southbound M6 from junction 21 for Warrington and Irlam. A diversion for the two overnight carriageway closures will operate between junction 21a of the M6 at Croft Interchange and junction 19 of the M6 at Knutsford – via the eastbound M62, anti-clockwise M60, westbound M56 and southbound A556.
Drivers planning to use the southbound M6 during the day on Saturday and Sunday June 18 and 19 should expect congestion when the work is taking place, with two of the four lanes closed to drivers past the roadworks on Thelwall Viaduct.
National Highways is advising drivers to check traffic conditions along the motorway before setting out on journeys and choose an alternative route should they wish to avoid congestion.
