A crash involving eight vehicles has led to the closure of the M6 near Warrington this morning (Wednesday, March 11).


The crash happened at 8.39am between J21 at Woolston Interchange (Warrington, Irlam A57) and J21a (Croft Interchange).

Two HGVs, five cars and one van were involved in the crash, with one lorry straddling all lanes after jackknifing.

It means the M6 northbound is closed between J20 Lymm Interchange (NORTH WALES Runcorn Birkenhead M56, Lymm Warrington A50) and J21a Croft Interchange (Manchester, Bolton, Leeds M62, Liverpool, Southport M62 (M57).

More than 400 litres of diesel has been spilled across all lanes of the carriageway and Highways is warning of significant delays.

The road is likely to be closed until the afternoon due to the number and types of vehicles involved, and the extent of the diesel spillage.
