Junction 10 between the M25 and the A3 will close for three weekends as part of an ongoing improvement scheme, but both roads will remain open to traffic.

Ongoing works to improve junction 10 on the M25 will see a series of slip roads closed for three full weekends over October and at the beginning of November.

The slip roads on and off the M25 and A3 will shut, but the roads themselves will still be open for traffic. Drivers will just need to take a diversion to either junction 9 or Junction 11 to continue their journeys.

Closures will take place on the following weekends, from 9pm on Fridays until 6am the following Monday.

  • 4-7 October
  • 18-21 October
  • 1-4 November

The slip roads are being closed to make changes at junction 10 which will introduce lanes that bypass the traffic lights. It represents the first real benefit of the £300m scheme for drivers passing through.

Jonathan Wade, Senior Project Manager for National Highways said:

“It is important that the public know this is not a closure of the M25 as we have seen on three occasions earlier this year.

“Work continues on the junction 10 project and these three weekends will allow us to carry out the next phase of the scheme.

“I would urge drivers to think about how these slip road closures will affect their journeys and make sure they follow the official diversion routes we have provided.”

M25 junction 10 weekend closure diversions

There are a series of diversions in place over these weekends to guide drivers around the slip road closures. It’s important to follow these diversions as they avoid the London ULEZ zone, so straying from them could result in a fine if your car isn’t ULEZ compliant.
