Lorry overturns in four-vehicle motorway collision

A lorry has overturned following a four-vehicle collision on the M1.

National Highways said the motorway was closed northbound, between junction 16 for Northampton and junction 18 for Rugby in Warwickshire, following a collision shortly after 22:00 BST on Tuesday.

It said all emergency services, including Northamptonshire Police's Serious Collision Investigation Unit, had left the scene and a "complex recovery and clear-up work" was ongoing. The road would also need to be resurfaced.

It expected the closure to remain in place until about 21:00, it added.

Police have asked drivers to avoid the northbound section.

The force said would like to hear from any witnesses, or anyone with dashcam footage taken between 21:45 and 22:05, to get in touch.

"Any footage, no matter how insignificant it may seem, could prove vital to the investigation," it said.

Elsewhere in Northamptonshire, the A43 was closed at about 06:00 on Wednesday for several hours southbound between junction 15a for Northampton/M1 and the A5 at Towcester due to a spillage.

National Highways said it occurred after a diesel tank became detached from a heavy goods vehicle trailer and it had affected all lanes of the carriageway.

The road reopened at about 16:00.
