The M25 faces overnight closures every night this week as National Highways carries out a series of planned roadworks.
The closures are part of a series of planned roadworks listed by National Highways, scheduled between Monday, November 9, and Thursday, November 12.
The closures will affect routes towards Essex, Kent, Surrey, and Hertfordshire, with most set to start at 10pm and remain in place until 5.30am the following morning.
Motorists are being advised to plan ahead, allow extra time for journeys, and check for updates before travelling.
National Highways has issued a warning to drivers, advising them to check regularly for updates as roadwork schedules are subject to change at short notice, particularly during periods of poor weather.
The agency has also advised motorists to follow signed diversion routes where provided.
Seven closures are scheduled overnight from Monday into Tuesday, November 10.
Eight closures are scheduled from Tuesday evening into Wednesday, November 11.
Six closures are planned overnight into Thursday, November 12.
Thursday will see the highest number of planned closures this week, with nine restrictions scheduled overnight into Friday, November 13.
Several sections of the M25 are set to face repeated overnight closures throughout the week.
These include the clockwise carriageway between junctions 28 and 29 near Brentwood in Essex and the anti-clockwise carriageway between junctions 17 and 16 near Rickmansworth.
The anti-clockwise section between junctions 3 and 2 in Kent will also be affected on all four nights.
Other repeated closures include the clockwise carriageway between junctions 14 and 15 near Heathrow Airport and restrictions around junction 25 near Enfield.
Drivers heading towards Heathrow, Dartford, and other major routes connecting to the M25 are being urged to check their journeys carefully.

It is the second major M25 disruption of the day. The M40 southbound was shut near the M25 earlier this morning after a crash involving four vehicles, and has since reopened, while the A243 in Leatherhead Road was closed after a police incident.
