Overview

• An HGV shed its load on the M6 northbound between Knutsford (J19) and the Lymm Interchange (J20) shortly after 1pm, triggering lane closures.
• National Highways reports about 12 miles of congestion back to J18 and warns drivers to expect roughly 90-minute delays.
• The link road from the M6 northbound to the M56 J9 westbound near Stretton is closed as part of the traffic management.
• Drivers intending to travel west at J20 are advised to continue to J21, turn around, and return to J20 as a diversion.
• Reports differ on the substance spilled, with outlets variously describing mud, soil and sewage, or oil and sewage, and officials have not confirmed the exact material.
