All slip roads at M25 junction 10 where it meets the A3 will be completely shut from Friday 13 to Monday 16 June as part of major upgrade works.
Drivers are being advised to prepare for significant disruption this weekend as the major interchange connecting the A3 with the M25 undergoes closure for the multi-million pound improvement scheme.
Every slip road will be shut at the M25’s junction 10 during the four-day closure period, meaning whilst motorists can continue travelling along both the A3 and M25 mainlines, they cannot exit or enter at this point.
Those driving northbound from Hampshire are strongly advised to follow official diversion routes to prevent congestion on surrounding local roads. These diversions differ from previous ones due to the nearby A320 closure, or alternatively motorists can use the M3 to bypass the area entirely.
Additional weekend closures are scheduled for the A3 between junction 10 and Painshill interchange on 20-23 June and 4-7 July.
Closure schedules may alter at short notice. Motorists can verify current information via the daily closures page or access real-time travel updates through the Traffic England website.
