Motorists are facing severe disruption after the A3 Hindhead Tunnel was closed due to a serious electrical fault with the tunnel's camera system, compounded by over-running overnight roadworks. The closure has affected the A3 from Liss to Liphook and between the A333 at Hindhead and the A283 at Milford.

A National Highways spokesperson said: “We are in the process of opening one lane on the northbound carriageway of the Hindhead Tunnel to traffic, followed by one lane on the southbound – both with a 40mph speed limit for safety reasons. Follow updates on X @HighwaysSEAST for timings. We are working hard behind the scenes to rectify the technical issue as soon as possible and thank motorists for their patience.”

Signed diversions are in place. Drivers heading north should follow the ‘hollow diamond’ symbol from Longmoor using the A325 and A31. Southbound drivers should follow the ‘solid triangle’ symbol from the Stag Hill interchange, also via the A31 and A325.
