One of the two lanes was blocked and long queues formed after the pile-up at junction 9 for Clayton Brook around 1pm. Emergency services are at the scene, but there are currently no details of casualties. Queues formed back to Whittle-le-Woods. There were also tailbacks on the northbound carriageway of the M6 in the same area as heavier than normal Friday afternoon traffic led to delays. Earlier a three vehicle crash on the northbound between junctions 28 and 29 caused minor delays. No-one was seriously injured. Police say there was also a minor collision on the opposite side of the motorway caused by motorists “rubber necking.”
