An infrastructure issue has closed the A3 southbound between the A283 near Milford and the A333 Hindhead Tunnel. National Highways have said the tunnel and a stretch of the major road remains closed due to a technical fault affecting one of the traffic signals on Thursday, January 9.

The nature of the issue means that there is no set time for the road to reopen but National Highways expects that it will be later today (January 9). The issue was first reported at around 2am and specialist service providers have been on site ever since.

In the meantime traffic has had to be diverted from the area. Drivers at the scene of the closure are being diverted locally while there is a much longer diversion for those travelling from further afield to continue using the A3 southbound.

Road users are advised to follow the solid triangle diversion symbol visible on local road signs:

  • From the A3 southbound, leave at the Stag Hill interchange (Hogs Back) and join the A31 towards Farnham.

  • Continue for approximately 7 miles, to the Shepherd and Flock roundabout.

  • Use the 1st exit and continue on the A31 Farnham Bypass.

  • Continue to the B3001 junction.

  • Cross over this junction to roundabout A31/ A325.

  • Take the 1st exit A325 and follow it along its entire length to the Longmoor Interchange roundabout.

  • Take the second exit on the roundabout to re-joining the A3 Southbound.

If this impacts your route then you will need to add extra journey time, re-route or delay your journey. You can follow the latest updates on this issue with our live blog here.
