The accident happened at around 7.30am on 6 February after a collision between a lorry and a car, say police.
All lanes re-opened at around 8.30am but delays were still reported to junction 29 of the M65 and junction 9 of the M61.
In a separate incident one lane was closed on M55 Westbound after an accident.
The accident happened at around 7.30am when a car is believed to have collided with a barrier, say police.
Lanes re-opened at around 8.30am after an earlier closure between M6 junction 32 at Broughton Interchange and junction 1 for Fulwood.
Nobody is believed to have been seriously injured in either incident.
