M25 set for third full weekend closure as work continues on £317m improvement project

• Motorway to be shut between junctions 10 and 11 from 9pm Friday 12 July to 6am Monday 15 July 2024
• Drivers again warned to expect delays and only travel if necessary
• Following our travel advice instead of satellite navigation system diversions will be key to reducing congestion

Part of the M25 is due to close next month to allow for further works.

The motorway between junctions 10 and 11 will be closed from 9pm Friday 12 July to 6am Monday 15 July 2024 for the construction and installation of a bridge on the western gyratory of the roundabout at Junction 10.

The new bridge, consisting of 68 beams, each weighing 16 tonnes, and another four beams weighing 40 tonnes, will be installed as part of ongoing work to make journeys safer and reduce pollution. The previous closure in May saw identical work being carried out on the eastern gyratory.

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.”

This is the third of five full weekend closures of the M25 to take place with a further two due later this year. National Highways and delivery partner Balfour Beatty Atkins are working with key stakeholders in the lead up to this closure, including emergency services, Surrey County Council, local businesses and Gatwick and Heathrow Airports. 

Local residents, holidaymakers, concertgoers and sports fans should plan their journeys in advance and make sure they allow extra time or make alternative travel arrangements.

Diversion routes
