Massive A3 Closure in Surrey This Weekend! National Highways has slammed shut the A3 in both directions at Wisley, Surrey, from 9pm Friday, 11 April until 6am Monday, 14 April. This 57-hour shutdown is part of crucial bridge and junction upgrade works at the M25 Junction 10 interchange — a notorious traffic bottleneck.
A3 Full Closure Details
- Closed Section: A3 between M25 Junction 10 and Painshill Roundabout (A245)
- Duration: 9pm Friday to 6am Monday (57 hours)
- Purpose: Long-term safety and traffic flow improvements at one of the UK’s busiest motorway junctions
What Drivers Must Know
While the A3 will be completely closed between the designated points, northbound access at Painshill from Byfleet Road remains open. National Highways warns commuters to plan ahead, expect delays, and follow official diversion routes.
This shutdown is part of the M25 Junction 10 improvement project, aimed at slashing congestion and boosting safety where the M25 meets the A3 — a grinding pain for Surrey commuters and long-haul drivers alike.

National Highways will provide ongoing updates via social media using the hashtag #BWW (Bridge Work Wednesday). Drivers should check live traffic feeds and diversion instructions before hitting the road this weekend.
