Delays have been blamed on ‘extreme weather.’
A section of the motorway will be closed for two out of three weekends next month to allow for demolition works, as part of a £317-million project to improve Junction 10 which is the A3 Wisley Interchange.
Jonathan Wade, National Highways Senior Project Manager, said: “Periods of extreme weather in 2024 delayed some elements of our work but since then we’ve worked hard to recoup that time and still complete the on-road elements on schedule.
“We are already seeing some of the benefits of this project, which will help reduce congestion, create a smoother flow of traffic and provide safer journeys for thousands every day.”
The Junction 10 improvement scheme will see an increase in the number of lanes leading to the junction.
National Highways says it will also make it easier and safer to enter and exit the M25, provide safer entry roads for Wisley, Pyrford, Old Byfleet and the RHS Garden Wisley, and will reduce the pollution caused by traffic jams.
Diversion routes for each of these closures will be announced and published closer to each weekend.
