Heysen Tunnels

The Heysen Tunnels are located on the South Eastern Freeway between Adelaide and Crafers.

Reporting a breakdown in the tunnels

If your vehicle breaks down in the tunnels alert the Traffic Management Centre by:

  • using a roadside emergency phone within the tunnels, or
  • telephoning 1800 018 313.

The operator will advise what action to take.

If you witness or are involved in a traffic incident in the tunnels you need to report it to SA Police.

There are two Heysen Tunnels running side-by-side. One is city-bound and the other is hills-bound.

Each tunnel:

  • has three lanes, each 3.5 metres wide
  • has a 90 km/hour speed limit, and takes about 20 seconds to drive through
