Traffic is being delayed by about two-and-a-half hours on a section of the M25 after a "serious" lorry fire resulted in 12 miles (19.3km) of congestion, National Highways says.
On Friday morning, National Highways said two of three lanes on the clockwise carriageway between junction five, near Sevenoaks in Kent, and junction six, near Godstone in Surrey, had been closed.
Surrey Police said it was made aware of the incident at about 01:30 and Surrey Fire and Rescue Service said it left the scene at about 03:15 as the blaze had been extinguished.
Traffic monitoring site Inrix said one lane was still closed as of 09:00 but "severe delays" remained.
Inrix explained that congestion had also spread to the A25 through Sundridge, Oxted and Godstone.
Delays of almost an hour are affecting traffic travelling westbound on the M26 leading up to the M25 at junction five, Inrix said.
Just after 09.15 National Highways said the lorry's load had been removed and recovery of the vehicle could now commence.
Surrey Fire and Rescue Service said it attended the incident along with Kent Fire and Rescue Service and there were no causalities.
