Motorists are advised to plan ahead as a series of overnight lane and road closures will be in place on the A3 near Junction 10 (Wisley) during the week commencing Monday 15 June 2026. 

These closures are part of the ongoing improvement works at M25 Junction 10 and are necessary to allow work to be carried out safely. 

Please note that while closure times are scheduled, they may vary depending on traffic conditions and when it is safe to close the road.

Time: 10:00pm – 5:30am 

A lane closure will be in place on the northbound A3 between Wisley and Painshill for two nights.
