A casualty was taken to hospital by air ambulance following a crash on the M6 this evening.
Six vehicles were involved in the incident on the northbound carriageway of the M6 between junction 31 and 31A at around 7pm.
Lancashire Fire and Rescue Service said firefighters from Bamber Bridge and Preston attended the scene and assisted paramedics, the police and Highways Agency to make the scene safe.
There were several casualties.
One was taken to hospital by air ambulance and the others were taken to hospital by road ambulances.
Firefighters remained at the scene until about 8pm.
In another incident on the northbound carriageway, shortly before 7.30pm, firefighters were called by paramedics to the scene of a collision involving a vehicle which had collided with the central reservation between junction 30 and 31.
One female casualty was reported trapped, however when crews arrived at the scene the casualty was already out of the vehicle.
Crews assisted Traffic Control Officers in moving the vehicle over to the hard shoulder.
Police say a diesel spillage led to a number of crashes that resulted in the closure of the M6 motorway at Preston this evening.
The motorway has since reopened, NW motorway police reported on Twitter this morning that J31A north exit of the M6 will be closed all day, as well as lane one of the M6 from J31-J31A for resurfacing.
