Junction improvement programme - M25 junction 10 and A3 Wisley interchange

M25 full weekend closure – 12 to 15 July

National Highways is closing the M25 between junction 10 at Wisley and junction 11 at Chertsey from 9pm Friday 12 July to 6am Monday 15 July. Please visit the National Highways website for more information and diversion routes.

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.
