A third full closure on the M25 in 2024 is set to take place over a weekend in July, which could impact some Hampshire drivers.

The motorway will be shut between Junctions 10 and 11 from 9pm on Friday, July 12 to 6am on Monday, July 15.

This closure is taking place to allow for construction and installation of a bridge on the western gyratory of the roundabout at Junction 10.

Previously in 2024, a full closure on the M25 took place over weekends in March and May, and a further two are planned for later in the year.

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.”

What diversion routes will be in place for the M25?

Hampshire drivers who were planning to use the M25 over the weekend of July 12-15 will need to follow the diversion route that will be in place.

According to National Highways these are the routes you should follow, depending on what direction you are coming from:

  • Junction 10 - Junction 11: exit the M25 at J10 and take the 3rd exit to the north bound A3 to the A245 Painshill Junction, A245 towards Woking, and Byfleet, then at the Six Crossroads Roundabout take the 5th exit to the A320 continuing to M25 Junction 11 where the diversion will end. 
  • Junction 11 - Junction 10: exit the M25 at J11 and take the 3rd exit to the A320 south towards Woking, then at the Six Crossroads Roundabout take the A245 towards Byfleet, continue on the A245 to the A3 Painshill junction, then take the 3rd exit to the southbound A3 to Junction 10 where the diversion will end.  

In a statement, National Highways added: "This is the third of five full weekend closures of the M25 to take place with a further two due later this year.
