National Highways is closing the A3 between M25 junction 10 and the Painshill roundabout/A245 from 9pm Friday 4 July to 6am Monday 7 July.
Please visit the , 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.
