A section of the M25 will be completely closed this weekend – the third of five full-weekend closures affecting the major road as part of a £317m upgrade.

  • Third full-weekend closure of M25 section
  • Motorway closed between Junctions 10 and 11
  • From 9pm Friday 12 July to 6am Monday 15 July
  • Delays expected as diversions will be put in place
  • Third full-weekend closure of Wisley upgrade
  • Two more closures planned between July and September

The M25 motorway will be closed between junctions 10 and 11 from 9pm on Friday 12 July until 6am on Monday 15 July for the construction and installation of a bridge on the roundabout at junction 10.

National Highways is warning drivers to expect delays and only travel if necessary. It’s also urging drivers to ignore their sat navs and only follow official diversions.

“The previous two closures have gone well with significant progress being made during both,” said Jonathan Wade, National Highways senior project manager. “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 sat-navs and follow our diversion route instead.”

This closure has the potential to affect people travelling from the north for the Goodwood Festival of Speed this weekend. You’ll need to plan ahead and leave plenty of time for delays if you’re planning to attend the event.

What is the diversion route for the M25 closure?

These junctions are important for traffic travelling to or from Heathrow and Gatwick airports, the ports of Dover or Portsmouth, and can be an area of heavy congestion. Drivers heading to Wimbledon in south west London for the tennis finals on Saturday 13 and Sunday 14 July could also be affected.

Clockwise Junction 10 to 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.

Anti-clockwise Junction 11 to 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.

Why is the M25 closing at Junction 10?

The closure is to allow contractors to install a new bridge as part of the £317m ‘Junction 10 improvement scheme’ to increase the number of lanes to help improve traffic flow as part of the government’s £24bn Road Investment Strategy.

The previous full closure in May saw identical work being carried out on the eastern gyratory. The first M25 closure at the junction was in March, while there was an overnight westbound closure earlier this month.
