Two lanes of the M6 northbound were closed for almost an hour this afternoon after a crash involving a number of vehicles.
The Highways Agency said traffic had to be halted altogether for a short time across all four lanes between junction 30 (M61) and junction 31 (Tickled Trout) as emergency services raced to the scene.
The collision happened at around 4.20pm and long rush hour queues built up on both the M6 and M61.
There were also queues as drivers on the southbound carriageway slowed to check out what was happening.
All four lanes of the southbound were re-opened within the hour. It is not known if there have been any serious injuries.
