Some of these closures are due to long-running projects, such as the £317 million road-widening scheme at the M25‘s Wisley Interchange (junction 10). Others involve routine maintenance, including vegetation trimming, electrical work on local infrastructure, and drain clearance to reduce the risk of flooding.
While these works are essential, they can cause significant disruption, so it’s advisable to plan if you need to travel during this time.
The official recommendation is to avoid travelling through affected areas where possible. However, diversions will be in place for those who must pass through.
Here’s a closer look at when the M25 will be temporarily closed and which sections will be affected over the next week.
When will the M25 be closed?
National Highways has announced various closures affecting the M25 over the next few days.
Overnight closures will typically open close at around 8pm (unless otherwise specified) and open again by 6am the next day. If the work takes longer than planned, National Highways will usually put up signs for diversions to ensure you can get through.
Between 10pm until 5.30am the following morning, the M25 will be closed in the following areas:
Between 10pm and 5.30am the next day, the following closure will be in place:
- The M25 anticlockwise slip road between junction 5 (Chevening/Chipstead) and the A21 (Sevenoaks bypass)
Towards the end of the week, you should be aware of the following closure between 10pm and 5.30am the next day:
- The M25 anticlockwise slip road between junction 5 (Chevening/Chipstead) and the A21 (Sevenoaks bypass)
How to get around the M25 closures
With the closures affecting slip roads, providing diversions may prove challenging.
Instead, it’s advisable to use alternative routes or back roads to reach the nearest open junction.
For instance, if you need to access the M25 anticlockwise exit slip road at Junction 12, consider heading to Junction 11 or 13 instead.
Plan your journey and familiarise yourself with the best alternative routes to minimise delays.
