Hahndorf Township Improvements and Access Upgrade

Project Update

Following community feedback and further technical assessments, the approved solution is now confirmed for the Hahndorf Township Improvements and Access Upgrade Project. The project will now progress to the next phase of design. Construction is expected to commence in 2023.

The Department for Infrastructure and Transport (the Department) would like to thank everyone who has provided feedback on the project and for their patience while extended investigations and assessments have occurred as part of the project planning and development process.

Key features of the approved solution

The key 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. Consultation on the Mount Barker Interchange upgrade design was completed in March 2022.

• Hahndorf Main Street Upgrade – revitalisation and improvements 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 further 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 approved 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; and • support for local businesses and economic growth in the area.
