Commuters are facing delays on the southbound carriageway this morning (August 14) after a lorry jackknifed between Botany Bay and Rivington Services.
Police and Highways officers are at the scene and lane 1 (of 3) has been closed between junctions 6 (Horwich Interchange) and 8 (Chorley).
Highways England said it expects congestion and delays until 9.45am.
Recovery is at the scene to remove the stricken lorry from the hard shoulder.
Lane 1 will remain closed until recovery is complete as the lorry is still partially obstructing the carriageway.
This incident is now clear and all lanes are open.
Highways England expects residual delays of up to 15 minutes between junctions 6 (Horwich) and 8 (Chorley).
