Motorists on the M6 faced long delays on Monday morning after a multi-vehicle crash led to the temporary closure of all lanes on the northbound carriageway at the Thelwall Viaduct, near Warrington. The incident occurred at junction 21 around 7.50am, prompting emergency services to attend the scene.
All lanes were closed for approximately 20 minutes before reopening just before 8.45am. However, severe congestion persisted, with queues stretching back to junction 19 at Knutsford. Traffic monitoring service Inrix reported delays of up to 65 minutes above normal travel times.
National Highways North West confirmed on X that lanes three and four were initially closed due to the collision, with North West Ambulance Service and traffic officers on site. The crash caused significant disruption during the morning rush hour.
By mid-morning, all lanes had reopened and delays began to ease. Inrix later updated that long delays had cleared, though residual congestion remained for some time. No further details on injuries or vehicle involvement have been released.
