M25 closure: Details of third weekend closure of section of motorway - diversion routes

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

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.

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 said it is part of a £317 million improvement project to increase the number of lanes to make it easier to enter and exit the M25 at 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 sat navs and follow our diversion route instead.”

M25 closure diversions

The motorway between junctions 10 and 11 will be closed in both directions from 9pm Friday July 12 to 6am Monday July 15.

National Highways has advised the following diversion routes.

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. 

The weekend sees a host of events taking place, including the Goodwood Festival of Speed and people travelling to London for the televised Euros final, meaning even more cars than usual will be out.

That’ll be in addition to families heading to Thorpe Park, as well as people going to Gatwick and Heathrow airports.
