National Highways has issued a reminder that the M25 will be closed in both directions between junctions 10 and 11 from:
- 9pm on Friday 7 March until 6am on Monday 10 March 2025
- 9pm on Friday 21 March until 6am on Monday 24 March 2025

This is part of an ongoing scheme to build a new central gyratory to improve the capacity for vehicles moving between the M25 and A3. The project has got to a point where the original two gyratory bridges will be demolished, one during each closure.
Diversions will be in place in both directions. Delays are expected to journeys taking place within the area during the periods specified.
Check the National Highways website for diversion and more details.
