His next of kin are being supported by specially trained officers.

Detective Chief Inspector Mike Bettington, of the Roads Policing Department, said: “Firstly, our thoughts are with the man’s loved ones and everyone else involved in dealing with this road traffic collision.

Both carriageways between junctions 4 and 5 were closed following the collision.

The southbound lanes have now reopened and northbound lanes have partially reopened.

The lane closure is expected to be in place until later this afternoon, police said.

Drivers are advised to avoid the area.

DCI Bettington added: “At this time this collision is not being treated as suspicious but I am appealing for any witnesses to this incident to please come forward and assist us with our enquiries.

“I’d also ask anyone with a dash-cam who was in the area just prior to or at the time of the collision to check any footage in case it has captured something that could help our investigation."
