The M25 will once again be closed in both ways between junction 10 Wisley and junction 11 Addlestone from 9pm Friday 11th July to 6am Monday 15th July so a new bridge can be installed.
National Highways are asking drive only to travel if your journey is necessary. A detailed diversion has been set up, and drivers are being urged NOT to rely on their Sat Navs but to follow the diversion routes instead.
Diversion route
The local diversion route is the same for both directions:
Junction 10 to Junction 11
North bound A3 to Painshill Junction, A245 towards Woking, and then A320 to M25 Junction 11.
Junction 11 to Junction 10
A320 south towards Woking, A245 towards Byfleet and Painshill junction, Southbound A3 to Junction 10.
Avoiding the closure by taking the M25 via the Dartford Crossing may also be quicker.
There are concerns that Sat Navs may direct vehicles, including lorries, onto smaller town roads, causing significant congestion alongside the delays that will happen with the diversions. So please follow the diversion route and not your SatNav.
The M25 junction 10 project profile page tells the story of our ongoing work during 2024/25 to transform the junction and surrounding area.
