M25 closure 15 to 18 March

Planned weekend closures on the M25 and A3

National Highways is planning to close a section of the M25 between junction 10 at Wisley to junction 11 at Chertsey, starting overnight on Friday 15 March and continuing until early morning on Monday 18 March. This is for demolition works and gantry installation at the Wisley interchange.

There will be official diversions, but there is likely to be traffic and travel disruption right across Surrey. Please consider this when making plans, and check for traffic updates before travelling.

Full details will be available on the National Highways M25 Junction 10 project website. Please keep checking this page for the latest information.
