M25 Closures

What happened?

Earlier in March, National Highways closed a section of the M25 between junction 10 at Wisley to junction 11 at Chertsey. The closure started from 11pm on Friday 15 March and was due to reopen at 5.45am on Monday 18 March.

The closure was to demolish a bridge and install a huge gantry at the Wisley interchange.

This was the first time there has been a scheduled daytime closure of all lanes on the M25 since it opened in 1986.

Whilst there was some disruption the closure was a success as widespread delays, which may people feared, did not materialise. The bridge was demolished, a new gantry installed and the M25 was open in both directions 8 hours ahead of schedule.

We'd like to say a massive 'thank you' to everyone for your patience and following our travel advice.

Diversions

Official diversions from National Highways directed drivers to travel around the M25 to avoid the closed section in Surrey; while local diversions took clockwise traffic off the A3 at Painshill, then through Byfleet and West Byfleet towards Woking, and then to Ottershaw.

Surrey Highways kept residents up to date over the weekend by monitoring traffic on the diversion routes.

Upcoming M25 closures

National Highways is planning further significant closures throughout 2024 linked to the work at Wisley interchange.

There will be regular overnight closures and a series of full weekend closures on either the A3 or M25 over the coming months. Drivers are advised to keep checking the National Highways M25 Junction 10 project website for the latest dates when making plans and before travelling.

You can also sign up to our Highways Update newsletter to get the latest updates on the closures and other highways issues from across the county. Don't forget to follow the Surrey Highways Facebook and X accounts.
