A lorry carrying hay bales which caught on fire on the M25 has caused significant delays to traffic.
The anti-clockwise lane in Hertfordshire is closed between J25 Waltham Cross Interchange and J24 Potters Bar Interchange.
The traffic inside the road closure is in the process of being released.
National Highways said it expected two-hour delays and 13 miles of congestion from J27.
In a post on X, it said: âPlease be patient we’ll try and get you moving again soon.â
It reported the incident at 5.50am on Tuesday and said Hertfordshire Fire and Rescue, London Fire Service and National Highways were in attendance.
Earlier this month, the M25 was closed after a lorry carrying rubber car tyres burst into flames across four lanes of traffic.
