M25 Weekend Closure: Major Disruption as £317M Roadworks Continue

A section of the M25 is closed this weekend as part of a £317 million project to improve traffic flow by adding extra lanes. All slip roads at junction 10 near Wisley, Surrey, were shut at 21:00 GMT on Friday and are set to reopen by 06:00 on Monday. The project, which began in 2022, has faced delays of around nine months due to extreme weather conditions. While both the A3 and M25 remain open, drivers cannot switch between them at junction 10. The AA has warned of increased congestion on surrounding roads, particularly the A3 near Wisley.

Additional closures are scheduled between junctions 10 and 11 from 7-10 March and 21-24 March, allowing for lane widening, safety barriers, and road signage improvements. Motorists are advised to plan ahead and use alternative routes to avoid long delays. No further full closures of the M25 are planned after March, though some lane restrictions may continue. Authorities recommend checking live traffic updates to stay informed about changing road conditions.

M25 Weekend Closure: Major Disruption as £317M Roadworks Continue

A section of the M25 has been temporarily closed as part of a £317 million project aimed at adding extra lanes to improve traffic flow and reduce congestion.

All slip roads at junction 10 near Wisley, Surrey, were shut at 21:00 GMT on Friday and are set to reopen by 06:00 on Monday. Authorities had advised drivers to avoid the western section of the M25 or anticipate delays if travel was necessary.

The project, which began in 2022 and was initially expected to be completed this summer, has been delayed by approximately nine months due to “periods of extreme weather.” These delays have added to concerns from commuters and logistics companies who rely on the M25 as a critical transport route.

Impact on Traffic and Alternative Routes

According to Surrey Highways, both the A3 and M25 will remain open, but drivers will not be able to switch between the two roads at junction 10 during the closure period. Motorists have been advised to plan their journeys in advance and use alternative routes where possible.

The AA has warned that surrounding roads, particularly those near the A3, are likely to experience higher traffic volumes as drivers seek alternative routes. Key congestion points are expected around Guildford and Woking, with delays potentially extending to other major connecting roads.

Drivers traveling between Heathrow and Gatwick airports, as well as those heading towards London or the South Coast, have been advised to allow extra time for their journeys. Freight companies and delivery services have also been urged to adjust their schedules accordingly to minimize disruptions.

Future Closures and Completion Timeline

Further closures are scheduled for the M25 between junction 10 (Wisley) and junction 11 (Woking) from 7 to 10 March and again from 21 to 24 March. These closures will allow for the completion of critical roadwork, including the widening of lanes, installation of new safety barriers, and improvements to road markings and signage.

Despite the delays, once completed, the project is expected to significantly enhance traffic capacity at junction 10, one of the busiest interchanges on the M25. The improvements aim to reduce congestion, improve safety, and support the increasing volume of vehicles using the motorway.

Following the planned closures in March, no additional shutdowns of the M25’s main carriageway are currently scheduled. However, periodic lane restrictions and overnight works may continue as the final stages of the project are completed.

Authorities have encouraged drivers to stay updated on road conditions through official channels, including the National Highways website and live traffic updates on radio stations.
