Traffic is stuck in a 13 mile queue on the M25 between Waltham Abbey and Enfield because of an accident between two lorries, a fuel spillage and recovery work.
Two lanes are closed anticlockwise between Junction 25 and 26 and cars are now stretching one mile beyond Junction 28.
Travel time is estimated at two hours.
There are long delays on the M25 due to an accident on the anticlockwise carriageway between J26 A121 (Waltham Abbey) and J25 A10 (Enfield). Traffic is already queueing all the way back to the M11.
