Every effort is made to reduce the impact on motorists by conducting this work during off-peak times.
The following lane restrictions will be in place:
- Crafers-bound tunnel lane restrictions (closure of two lanes) from 8:00pm Friday 25 August to 6:00am Saturday 26 August.
- Adelaide-bound tunnel lane restrictions (closure of two lanes) from 12:00am to 6:00am on Saturday 26 August.
Emergency vehicles will have access to the tunnels at all times. Speed restrictions will be in place at this location while the maintenance work is undertaken.
The safety of workers and the general public is paramount so please take care when travelling through work zones.
The Department of Planning, Transport, and Infrastructure thanks motorists for their patience.
