All lanes have reopened after a camper van overturned earlier.
The crash happened on the M25 clockwise between j21A and j21, close to St Albans at around 2.30pm.
Two lanes were initially shut and then the whole clockwise carriageway was temporarily closed to allow recovery of the vehicle.
There were no injuries.
The motorway is open, however there are delays clockwise between j18 and j20 as well as on the A405 in both directions between the M1 junction and the Noke roundabout.
