The westbound exit to Cobham services will also close.
Meanwhile, the eastbound anti-clockwise carriageway at Junction 10 will be closed, however drivers will exit at the slip road, go around the roundabout and rejoin at the entry slip road of the same junction.
What is the diversion route for the M25 closure?
- Travel anticlockwise to junction 8 (traffic already on the M25 and wanting to travel past junction 9 will be directed to leave the M25 at junction 8
- At junction 8, take the A217 exit towards London, Sutton, then turn left onto the A240
- At the Esso roundabout, turn right onto the A24 towards the A3 Tolworth junction
- At the Tolworth junction join the southbound A3 to towards the M25 at junction 10.
There is a separate route for overheight vehicles.
See information on the closure and the route of the diversion on the National Highways website.
The overnight closure of the westbound carriageway this weekend isn’t on the scale of the two full closures in March and May. Those full-weekend closures saw drivers being asked only to travel is necessary when the motorway was closed between junctions 9 at Leatherhead and 10 at Wisley.
What is happening at the M25 Junction 10
This weekend’s closure is 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.
A further three full closures are planned between now and September 2024.
Dates for the third closure of the M25 will be announced as soon as possible.
