Drivers told to plan ahead of M25 junction closure

Drivers are being warned to plan ahead for the closure of a junction of the M25 in Surrey.

Junction 10, connecting the A3 to the motorway, will be closed from 22:00 GMT on Saturday to 06:00 on Sunday, including all slip roads.

The A3 and M25 will remain open to through traffic, but drivers will not be able to leave or join either road as normal, National Highways said.

Diversions will be in place.

National Highways said the junction was on the busiest section of the M25, with more than 300,000 vehicles passing through daily.

Improvement works, totalling £317m, are being carried out and are due for completion in mid-2025.

The works include new cycle routes, two new lanes on part of the A3, a larger roundabout with extra lanes and improvements to the local environment and wildlife.

National Highways said two further full closures of the motorway were planned in spring 2025.
