M25 closure: These are the diversion routes drivers can use during the second full weekend closure

This work will take place during a full weekend closure between junctions 9 (A243 Leatherhead) and 10 (A3 Wisley) from 9pm on Friday, May 10 to 6am on Monday, May 13.

These £317m essential works are one of five series of improvements to the M25 taking place this year, as part of the Government’s £24bn Road Investment Strategy (RIS2).

Jonathan Wade, National Highways senior project manager, said: “This is far from a repeat of the previous closure, as the alternative routes are longer and will be different for over height vehicles and all other traffic.

“Drivers listened to our advice last time which reduced motorway traffic levels by over two thirds and meant delays were limited.

“Our advice again is please only travel if absolutely necessary and make sure you give yourself extra time if you do choose to use the M25.”

Ahead of the second closure, National Highways have confirmed diversion routes will be in place.

A National Highways spokesperson said: “For the closure of the M25 between junction 9 A243 Leatherhead and junction 10 A3 Wisley, planned to take place during the weekend of May 11 and 12, there are four diversionary routes depending on the direction of travel and the type of vehicle.

“Each route will be clearly signposted and are as follows:
