M25 Motorway Closure: Important Details for Drivers
One of the UK’s most heavily trafficked motorways, the M25, is set to close in both directions tonight, prompting drivers to plan alternative routes. National Highways has announced this closure, which will impact thousands of motorists. The M25 was previously shut down yesterday and is scheduled for renovation work tonight.
The closure will take place overnight over two days this weekend, specifically between junctions 9 and 10. On Friday, March 28, the motorway was closed from 9 PM until 6 AM on Saturday, March 29. After a brief period of reopening, the M25 will again be closed from 9 PM tonight until 6 AM on Sunday, March 30.
Motorists traveling in the affected area, located just a few miles north of Guildford in Surrey, are advised to follow the designated diversion routes:
Eastbound (Anticlockwise) Diversion:
- Exit the M25 at junction 10 to access the northbound A3.
- Proceed via the A245, A307, A309, and A243.
- Rejoin the M25 at junction 9.
Westbound (Clockwise) Diversion:
- Exit the M25 at junction 8 to join the A217.
- Follow the A240, A24, and A240 to Tolworth.
- At Tolworth, connect to the southbound A3.
- Rejoin the M25 at junction 10.
For over-height vehicles, a separate diversion route is in place:
Over-Height Vehicle Diversion:
- Divert off the M25 at junction 9 to travel north on the A243.
- Proceed to the A3 Hook junction.
- Follow the A309, A307, and A245 to reach the A3 Painshill junction.
- Finally, rejoin the M25 at junction 10.
Additionally, it is important to note that access to the Cobham services will be restricted during the closure, allowing entry only for employees and hotel guests. National Highways has initiated the significant M25 junction 10 project to alleviate congestion, enhance traffic flow, and ensure safer travel experiences.
A range of roadworks is underway, including the construction of two new bridges and plans to restore local greenery. During the weekend of January 17 to 20, Cockrow Bridge was installed, marking a significant milestone as the world’s first heathland bridge, designed to provide a safe passage for both people and wildlife across the A3.
These improvements indicate that this weekend’s closure will not be the last, as the project is expected to extend until Spring 2026. National Highways urges all drivers to stay informed by monitoring announcements regarding upcoming closures.
