A COLLISION has brought traffic to a halt through the roadworks between junction 19 at Knutsford and 18 at Middlewich.

North West Motorway Police report a two-vehicle accident at around midday on the southbound carriageway.

Queues had already formed between the two junctions and up to junction 20A at the M56, with one lane closed when a car towing a caravan broke down before 11am.

Police and traffic officers have been called to the scene.

Another vehicle has also broken down in the middle lane of the M6 north near Knutsford, meaning there are now queues in both directions.
