Section of the A3 to close over the weekend
National HighwaysA section of the A3 will close in both directions over the weekend as the £317m Wisley interchange upgrade continues in Surrey.
National Highways has said the closure will be between the M25 Junction 10 and the Painshill Roundabout in Cobham, lasting from 21:00 BST on Friday until 06:00 on Monday.
The works include installing an overhead road sign holder, drainage work in the central reservation and installing trenches for technology across all lanes.
Diversions will be in place across the weekend.
The same section of the A3 will be closed again from 4 to 7 July, say National Highways.
The works are part of a project to ease congestion on the A3 and the Wisley Interchange and are due for completion in 2026.
