Closures on the M25 and M26 due to a lorry fire are likely to last until midday, road users have been warned.
The M25 is closed clockwise between J5 near Sevenoaks and J6 near Godstone/Caterham, according to Highways England. Diversions are in place.
Traffic on the M26 westbound between J2A near Wrotham Heath and M25/A21 has also been diverted.
Six crews from Surrey Fire and Rescue and officers from Surrey Police attended the scene of the incident late on Sunday night.
A spokeswoman for Surrey Fire and Rescue Service said shortly after 07:00 BST that there was still one engine at the scene.
She said: “The crew are currently dampening down hot spots.
“We’d like to take this opportunity to thank all staff and partners who were involved in tackling this blaze.”
Highways England said specialist recovery would be required and the road surface would likely need to be resurfaced.
