Delays and lanes closed on M6 at Thelwall Viaduct after serious crash

All traffic heading northbound was temporarily held from around 7pm as emergency services closed the motorway.

Officers attended the scene and found a lorry had come off the carriageway and landed on the embankment below the bridge.

The driver of the lorry is not believed to have suffered any life-threatening injuries. Trapped traffic is being released, with one lane open and three closed. A diversion is in place with motorists following the hollow diamond symbol along the A50 Knutsford Lane into Knutsford and on the A57 Manchester Road.
