Heysen Tunnels Safety Upgrade
Start of initial activities - Crafers bound tunnel
The Department for Infrastructure and Transport (the Department) is undertaking a major upgrade of the Heysen Tunnels to address current tunnel elements that are at the end of their service life, improve safety and provide improved traffic management and incident response capabilities.
The upgrade will include the design and installation of new tunnel lighting, ventilation, fire suppression and Intelligent Transport Systems.
The Australian and South Australian governments are jointly funding the Heysen Tunnels Safety Upgrade, which is expected to be completed in 2024.
Initial activities, including additional investigation works and the start of tunnel lining repairs are planned to start from Sunday, 19 March 2023.
To minimise the impacts to road users, the majority of works will be undertaken Sundays to Thursdays between 8pm and 6am. It is not anticipated that works will be undertaken on Friday and Saturday nights, or on public holidays, however advance notice will be provided by on site messaging boards if this changes.
From Sunday, 19 March 2023, the Crafers bound (up-track) tunnel will close between 8pm and 6am. During these closure times, the Adelaide bound (down-track) tunnel will accommodate traffic in both directions, via contraflow (see map and further information under 'Latest News and Publications' on the project website).
Works are expected to continue in the up-track tunnel for approximately two months. Further updates about this project and associated impact will be provided.
The Department appreciates your patience and co-operation whilst these important works are undertaken.
