A western section of the M25 remains partially closed after two lorries crashed leaving barrels of beer to cascade across the motorway.
The collision happened between junction 17 for Maple Cross in Hertfordshire and junction 16 for the M40 in Buckinghamshire.
Thames Valley Police said no one was hurt.
Motorists are still expecting delays as two lanes remain closed while highway crews clear the debris from the carriageway. They are expected to reopen at 12.30pm.
The other lanes were opened at 10am.
