Traffic is at a standstill on the M6 with an overturned lorry covering all four lanes.
The incident happened on the M6 northbound at around 2.15pm between junction 31, A59 Preston New Road, and junction 29, M65.
The M6 southbound is also moving slower than usual with motorists slowing to look at the accident, according to AA traffic.
Highways England have offered this diversion information - ‘Northbound traffic on the M6 is advised to take exit at junction 29 and follow the hollow diamond diversion. Take the M65 westbound and at the roundabout join the A6 towards Preston. Then take the A59 eastbound and rejoin the M6 at junction 31.
Northbound traffic on the M61 is advised to exit at junction 9 and take the M65 westbound and then follow the same diversion as above.’
In a statement they also said: “A HGV loaded with plastic crates has overturned between J30 and J31 blocking all four lanes. Highways England is working with emergency services to get the carriageway re-opened safely as soon as possible.
The HGV will need to be lifted from the scene and following that, a large diesel and oil spillage across all four lanes will need to be cleaned from the carriageway. So a time of re-opening cannot be anticipated at this stage.
A spokesman for Lancashire Police said: “The motorway is closed while we work with other services to clear the road. The driver of the lorry does not have any serious injuries.”
Emergency services are at the scene and North West Motorway Police say specialist recovery equipment is going to be needed to clear the vehicle.
Lancashire Road Police says the recovery and clean up operation has started.
More updates imminent.
