Heysen Tunnel Routine Maintenance Works

CONNECT - Message from the Chief Executive

19 April 2016

Motorists are advised of essential safety maintenance works which will require the partial closure of the Heysen Tunnels from Wednesday 20 April 2016.

This includes maintenance works on the essential electrical systems, including the ventilation, lighting, fire detection and emergency management systems.

 These works were unable to be completed during the recent bitumen works due to safety concerns and inaccessibility to tunnel equipment.

Associated traffic restrictions are as follows:

Wednesday, 20 April

  • Crafers bound tunnel lane restrictions (closure of one lane) from 8.30 am until 4.00 pm.
  • Adelaide bound tunnel lane restrictions (closure of one lane) from 9:00 am until 4:30 pm

Friday, 22 April to Saturday, 23 April

  • Adelaide bound traffic will be detoured via Eagle on the Hill from 7:00 pm Friday, 22 April until 8:00 am Saturday, 23 April.
  • Crafers bound traffic will be diverted into one lane of the Adelaide bound tunnel from 10:00 pm on Friday, 22 April until 8:00 am Saturday, 23 April.

Emergency vehicles will have access to the tunnels at all times.

Every effort is made to reduce the impact on motorists by conducting these work during off peak times.

The Department of Planning, Transport, and Infrastructure (DPTI) thanks motorists for their patience while these important tunnel maintenance works are undertaken.
