Motorists are being warned of congestion on the M25 affecting South Mimms, Potters Bar and St Albans.
There is very slow moving traffic on the anticlockwise carriageway between Junction 22 for St Albans and Junction 24 for Potters Bar.
Highways England states on its website that it is due to “load recovery”, adding it has caused one lane to close and delays are expected to persist until around 5pm.
Updates to follow.
