A3 Hindhead tunnel maintenance in Surrey

Work to maintain and improve the power supply to the Hindhead tunnel on the A3 between Surrey and Hampshire starts this weekend.

The work will start tonight (Friday 10 October) using closures of the tunnel in both directions and is due to be completed, weather permitting, on Saturday 22 November.

Highways Agency Project Manager Graham Link said:

The tunnel has state of the art technology and it is vital that we maintain and improve this equipment to ensure that road users continue to benefit from the improved traffic flows along the A3. The work we are doing will help make the tunnel more resilient if there is ever an interruption to the electricity supply, and will help to reduce the likelihood of unplanned closures.

As with previous work, the tunnel will be closed in both directions and we have planned this to take place overnight, when we know traffic flows are at their lowest, to minimise disruption.

The work will be carried out overnight, between 10pm and 6am on Fridays and between 9pm and 9am on Saturdays, on the following dates:

  • Friday 10 October
  • Saturday 11 October
  • Saturday 18 October
  • Saturday 25 October
  • Saturday 1 November
  • Saturday 8 November
  • Saturday 15 November
  • Saturday 22 November

A fully signed diversion route will be in place via the A31 and A325.

The Highways Agency manages 11 tunnels on the strategic road network in England and all of these require maintenance to ensure that road users remain safe. The Hindhead Tunnel is the newest tunnel on the road network and, since opening, it has brought huge benefits to drivers, the economy and the environment.
