M25 closes between J10 and J11 from March 7-10 for bridge demolition. Follow official detours and expect delays.
They are improving Junction 10; the project costs £317 million and should reduce traffic jams and improve safety. It’s a really busy, dangerous spot.
The M25 shuts in both directions between Wisley (J10) and Chertsey (J11). All slip roads at Junction 10 will also close. Expect lots of traffic on the A3, A245, and A320.
They need to demolish a bridge; this closure helps with the upgrade works. Junction 10 handles 300,000 vehicles daily, and the upgrade started in 2022.
The plan adds lanes at the junction, redesigning exits to prevent backups. New bridges improve access for walkers and cyclists. Completion is now set for spring 2026.
If you must travel clockwise, exit at J10. Take the A3 north toward Painshill, follow the A245, then use the A320 to rejoin at J11.
For anticlockwise travel, exit at J11; use the A320 southbound and follow A245 through Byfleet. Join the A3 to rejoin at J10. These routes will probably be very busy.
Don’t trust satnavs for shortcuts; they could send you on small roads. That will create more traffic in towns. Stick to the official routes.
Another closure happens later in March; the M25 shuts again from March 21 to 24 between Junctions 10 and 11. The same detour routes apply.
Heathrow and Gatwick trips will take longer; allow extra travel time to airports. Some National Express coaches will be affected. Check their website for updates.
Avoid travel if possible during the closure. If needed, use official detours and allow more time. Check traffic updates before you leave and consider using trains instead.
This work should help the motorway long term; it aims for smoother, safer traveling. Your patience is appreciated during these repairs. Soon, journeys will be better.
