Hahndorf Township Improvements and Access Upgrade

November 2023 update

The Australian Government has announced the outcomes of its Infrastructure Investment Program Review. The Review recommended that the Hahndorf Township Improvements and Access Upgrade will not receive Australian Government funding at this time. We are currently examining the outcomes of the Review and will share more information with the community as it’s available.

Features of the approved solution include:

Verdun Interchange upgrade

  • the existing interchange will be upgraded to a full interchange, allowing access to and from the South Eastern Freeway in all directions.

Mount Barker Interchange upgrade

  • the existing interchange will be upgraded to include the installation of a new three lane bridge across the South Eastern Freeway for northbound traffic; the conversion of the existing bridge to accommodate three lanes of southbound traffic and a new Shared Use Path; improved ramp capacity and new traffic signals to reduce congestion and improve safety.

Hahndorf Main Street Upgrade

  • revitalisation and upgrades to Hahndorf’s main street, Mount Barker Road (the Main Street) in collaboration with Mount Barker District Council.

Extension of Pioneer Women's Trail

  • the trail will be extended between Verdun and Hahndorf which will include a bridge replacement and widening over the Onkaparinga River to accommodate the new section of the trail.

Upgraded multi-purpose car park facility at Verdun

  • this upgrade will improve access to public transport.

Following community feedback and technical assessments, the previously proposed new interchange on the South Eastern Freeway near Hahndorf has been removed from the project scope acknowledging the impacts on the surrounding heritage and environment.

Key benefits

The decided solution will deliver several benefits to Hahndorf including:

  • less property acquisition and disruption to local residents, businesses, and the community by using the existing infrastructure where possible;
  • improved access and connectivity to the South Eastern Freeway to and from Hahndorf including removal of some traffic from the Main Street;
  • improved amenity, safety and connectivity for road users, pedestrians, cyclists, visitors and local residents using the Main Street;
  • preservation of Hahndorf’s heritage and character including heritage trees, buildings, and coach lighting;
  • improved bushfire and emergency access by adding additional ramp access to South Eastern Freeway at Verdun and improving access to South Eastern Freeway at Mount Barker;
  • support for local businesses and economic growth in the area; and
  • traffic modelling on the approved solution shows that there will be improvements to existing traffic and congestion along Hahndorf Main Street. The work on the Mount Barker and Verdun interchanges is expected to reduce traffic by 990 vehicles per day, including 110 trucks. These are vehicles currently travelling through Hahndorf to access the Freeway, who will now have an alternative route.

Considerable effort has been made to preserve the Main Street as the heart of this historic community, and to continue to shape this public area to maximise shared value by capitalising on community assets, inspiration, and potential.
