Roadworks/Closures: M25 Junc 10/A3 16-19 May

Published: 12 May 2025

Wisley interchange junction 10 closure – 16 -19 May

The Wisley interchange junction 10, including all entry and exit slip roads, will be closed in its entirety from 9pm on Friday 16 May to 6am Monday 19 May 2025.
While the A3 and the M25 will both remain open, the slip roads off and on the junction won’t be, meaning you won’t be able to leave or join the M25 or the A3 at junction 10.
This closure is to allow us to carry out the final resurfacing works on the gyratory and will be our last planned full weekend closure of the Wisley Interchange junction 10.
Please think about how this closure will affect your journeys and what alternative routes you should take.
This may include using the M3, M23 or A24 to get on to the M25 from the south or using the A316/M3, A23/M23 or the A24 to get on the M25 from London or the north of Surrey.
