Upcoming M25 Closure 7-10 March 2025

Posted in General News on Friday, March 7th, 2025

National Highways is delivering the M25 Junction 10 upgrade scheme which is due to finish in the spring of 2026. As part of these works, they have built a new central gyratory including two new bridges to improve the capacity for vehicles moving between the M25 and A3. They now need to demolish the original two gyratory bridges.

To safely complete the demolition of the bridges, National Highways require two full weekend closures of the M25 in both directions, between junctions 10 (Wisley) and 11 (Chertsey). Each closure will allow one bridge to be demolished.

The first of these two closures is this coming weekend:

9pm on Friday 7 March to 6am on Monday 10 March 2025
 

The diversion routes are:

Motorists travelling clockwise will be diverted from the M25 at junction 10 to use the A3 northbound travelling via the A245 at Painshill and the A320 to rejoin the M25 at junction 11.
 

Motorists travelling anticlockwise will be diverted from the M25 at junction 11 to join the A320, then the A245 to Painshill to use the A3 southbound to rejoin the M25 at junction 10.
 

National Highways expect delays which they apologise for.

There will be more full weekend closures of the M25 and A3 during 2025, and they will notify us of these closures as they are confirmed. Please also visit their webpage at hhttps://nationalhighways.co.uk/our-roads/south-east/m25-junction-10 for more information

This next closure coincides with other ongoing improvements on our network including the installation of additional emergency areas on the M25 J23-27, M25 J5-7, M4 J10-12, M3 J2-4a and M20 J3-5. More information about these works can be found here.
