Firefighters are tackling a lorry blaze on the M25.
Officers from Hertfordshire Fire and Rescue were called at 1.50pm and are tackling a blaze on the clockwise M25, between Junction 16 (Uxbridge) and Junction 17 (Maple Cross).
Two lanes are closed while firefighters deal with the fire, and the lorry has been moved over to the hard-shoulder.
The Highways Agency had stopped all traffic, but they re-opened lanes three and four at 2.15pm.
One crew from Rickmansworth has attended the scene.
