When is the M25 section being closed?

The section will be closed in both directions from 9pm on Friday July 12 to 6am on Monday July 15 between junctions 10 and 11. The first of these intersects with the A3 and junction 11 intersects with the A320.
Two further closures are scheduled for later in the year, although the dates have not yet been disclosed.
Travel advice
National Highways is once again recommending drivers either skip their trip entirely or follow the designated detours.
“Only travel if necessary. We’re grateful to all drivers who avoided previous closures and completed their journeys in other ways. We urge you to do the same again.
“If you do travel, expect delays and please leave a lot of extra time for your journey.”
Diversion route
The diversion route is the same whether you are going from junction 10 to 11 or 11 to 10.
To go from junction 10 to junction 11, motorists are advised to use the northbound A3 to Painshill junction, A245 towards Woking and finally the A320 to junction 11.
To go from junction 11 to junction 10 use the A320 south towards Woking, A245 towards Byfleet and Painshill junction and then the southbound A3 to junction 10.
Jonathan Wade, National Highways senior project manager, said: “The previous two closures have gone well with significant progress being made during both.
“We would urge all drivers to follow the official diversion route as this is the best chance of reaching your destination in good time.
“Please ignore your satnavs and follow our diversion route instead.”
