A3 Hindhead Tunnel Southbound Closure Due To Technology Issue
Travellers using the A3 uk/where/hindhead/">Hindhead Tunnel are facing disruptions as the southbound tunnel has been closed due to a technology issue affecting traffic lights and barriers. The closure has prompted authorities to issue a diversion for road users.
Service providers are currently on the scene, working diligently to resolve the issue. However, in the meantime, motorists are advised to follow the solid triangle diversion symbol displayed on local road signs.
The recommended diversion route is as follows:
1. From the A3 Southbound, drivers should exit at the Stag Hill interchange (Hogs Back) and join the A31 towards Farnham. 2. Continue on the A31 for approximately 7 miles, until reaching the Shepherd and Flock roundabout. 3. At the roundabout, take the 1st exit to continue on the A31 Farnham Bypass. 4. Proceed to the B3001 junction, crossing over to the RBT A31/ A325. 5. Take the 1st exit onto the A325 and follow it along its entire length to the Longmoor Interchange. 6. Finally, cross over the RBT and join the A3 Southbound Longmoor on-slip.
Motorists planning to use this route are advised to allow extra time for their journey. The closure may necessitate rerouting or even delaying travel plans.
