M25 diversion route

Epsom and Ewell braces for M25 closure traffic


Greater chaos has been avoided by the Epsom and Ewell Times correcting the Highway Authority‘s belief you could turn off the northbound A3 to go south at the Hook Junction. “Thank you for your email of 19 April 2024 in relation to the M25 junction 10/A3 Wisley interchange improvement project and specifically regarding the error in the M25 weekend closure diversion route published on our webpage. I’d like to apologise for this error and to also thank you for bringing it to our attention. This has now been corrected….” wrote Chris Davis, the Project Support Officer.

The Highways Authority has announced the closure of a section of the M25 motorway between junctions 9 (A243 Leatherhead) and 10 (A3 Wisley) from 9pm Friday, May 10, to 6am Monday, May 13, 2024. This closure is necessary for the installation of a new bridge.

Travellers are advised to avoid unnecessary journeys during this period, with the authority expressing gratitude to drivers who complied with similar closures in the past. A 19-mile diversion route has been planned, utilizing the A3 and the A240. Drivers are urged to follow this diversion and not rely on their SatNav systems.

For clockwise diversion, except for over-height vehicles, drivers are advised to leave the M25 at junction 8 onto the A217 (Reigate), then follow signs for London, Sutton, and Kingston on the A217 and A240. At the Esso roundabout, they should turn right onto the A24 (A240) towards Kingston, then left onto the A3 towards Portsmouth and Guildford. After 9½ miles, they can rejoin the M25 at junction 10.

Fortunately, the works at the Tolworth roundabout have all but completed for traffic. The northbound A240 has four lanes to filter at the junction approach.

For anticlockwise diversion, except for over-height vehicles, drivers should leave the M25 at junction 10 and join the A3 towards London. After 9½ miles, they should turn right onto the A240 towards Epsom and Reigate, then follow signs for Reigate and the M25 on the A240 and A217. After 3½ miles, they can rejoin the M25 at junction 8.

Drivers using the signed diversion route will not incur any Ultra Low Emission Zone (ULEZ) charges that may usually apply in London. However, over-height vehicles must follow a different diversion route to avoid a low bridge.

The Highways Authority also announced plans for three more weekend closures of the M25 this year, with no closures scheduled for June. The remaining closures will occur between July and the end of 2024, with dates to be announced following the May closure.
