M25 weekend closure
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.
There will be official diversions, but there is likely to be traffic and travel disruption right across Surrey. Full details will be available on the National Highways website. Please keep checking National Highways website for the latest information, including details of further A3 and M25 closures throughout 2024.
Why and how National Highways are improving the M25 junction 10/A3 Wisley interchange
Junction 10 is the busiest section of the M25, with over 270,000 vehicles travelling through it every day. Due to the volume of traffic and the resulting queues, this area of their network has a very poor safety record and holds one of the highest collision rates across the National Highways network.
Their improvements will reduce delays, smooth traffic flow and create safer journeys for all.
