Traffic delays on motorway after van overturns

TRAFFIC is being held up on the M6 near Warrington after a van overturned on Thelwall Viaduct.
All lanes of the northbound carriageway were, for a time, closed but Lane One has since re-opened enabling traffic to move.
But lengthy delays are expected and police and Highways England are advising drivers to try and avoid the area.
A 30mph speed limit is also in force.
Emergency services have been sent to the scene.
