Major closures on the M25, A3 and M3 this week as roadworks return for 2025

As we officially enter the second week of 2025, National Highways’ overnight road closures ramp up. After taking a break throughout the festive season, roadworks are now back in full force, with carriageways, link roads and slip roads shutting overnight for works.

National Highways will shut certain routes from as early as 9pm in Surrey for essential works. The team continue works at the Wisley Interchange, which is months away from completion, with a full weekend closure on the A3 planned later this month. National Highways gave SurreyLive an update on how work was progressing here.

Other major areas such as near Heathrow Airport at the M25 will shut, impacting travellers. Furthermore, link roads from the M25 to the M23 will also shut during a month-long raft of closures, impacting travellers at Gatwick Airport.

Overnight road closures may reopen as late as 10am the next morning in some cases, particularly on Saturday morning on the M25. Those heading out Saturday morning will need to take note of this closure near Wisley.

Due to weather conditions, road closures could take longer to reopen the following morning. This week Surrey is forecast for sub zero temperatures and snow, for more on weather, follow our live blog here.
