POLICE are advising motorists to avoid the M1 southbound today (Thursday) following an accident involving an overturned lorry.
The accident happened at around 6.20am this morning when a lorry overturned on the carriageway between junction 16 and 15a at Northampton.
Both sides of the motorway were closed to allow emergency services to deal with the incident.
The driver of the lorry has now been released from the vehicle and has been flown to University Hospital in Coventry but the air ambulance.
Now that the air ambulance has left the scene, the northbound carriageway has reopened.
The southbound carriageway remains closed and motorists travelling from Rugby are advised to avoid the area.
There are long delays back to J17 for Dunchurch and it has also has a knock-on effect on the A5 at Kilsby.
A spokesman for Northamptonshire Police said: “The Northamptonshire Police Collision Investigation team have been at the scene this morning investigating the circumstances that lead to the collision.
“Work will now take place to clear the road of the debris from the collision, as well as repair the road surface and crash barrier which were badly damaged in the incident.
“This work is vital to make sure the carriageway is safe for motorists when the road reopens.
“It is likely to take some time and so anyone planning on travelling on the M1 southbound between junctions 15a and 16 this afternoon are advised to find alternative routes.”
Diversions are still in place, however, both the A5 and A45 around Northampton are congested and so journeys are taking longer than usual.
