No interchange between the A3 and M25 over three weekends
National Highways is planning to close the gyratory at the junction 10 Wisley interchange over three weekends in October and November.
The M25 and A3 will both remain open during the closure, but the slip roads and roundabout at junction 10 will be closed. Drivers will not be able to change from the A3 to the M25 or vice versa.
The closures are planned over three weekends, which are as follows:
- 9pm on Friday 4 October to 6am on Monday 7 October
- 9pm on Friday 18 October to 6am on Monday 21 October
- 9pm on Friday 1 November to 6am on Monday 4 November
Whilst we don't expect the levels of congestion seen during the recent full weekend closures of the M25, there will be some disruption on the Surrey network as drivers who need to change between the A3 and M25 divert to local roads. Please consider this when making plans, and check for traffic updates before travelling.
Diversion information can be found on National Highways website.
