A truck rolled up the spread of the oil over M25 and causing huge tamps in a hurry on a hurry.
HGV collapsed into another transmission truck otherwise otherwise from the clockwise between Junction Six (Godstone) and five (Chevening) At about 3.45 on Wednesday.
Oil, diesel and waste are spilled on the main highway that leads traffic to a stalemate.
National highways warned the work of cleaning the “large spill” will be “extensive and complex”, and the path will now need to be re-set.
“Traffic caught in closing has now been cleared. Now the accident investigations are taken place,” the agency added.
Surrey Fire and Rescue Service said they were attended at the scene in which 45 minutes of delays are applied.
“The road was closed and is likely to be a while, which will affect the traffic in a hurry in the surrounding roads,” said the spokesman.
“Avoid an area and leave an extra path for your trip. Thanks to our partners who have also attended.”
They are advised for users on the way to follow the hollow square symbol to redirect to travel signs and come out of the orbital road to J6 before re-joined A25.
