    Share on Facebook Share on Twitter Share on Linkedin Email this link

    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.

    Upcoming temporary closure of Hahndorf/Woodside/Birdwood outbound off ramp and detour

    The Department for Infrastructure and Transport (the Department) is undertaking major pavement rehabilitation works on the South Eastern Freeway between Bridgewater and Callington.

    Works in the outbound lanes adjacent the Hahndorf/Woodside/Birdwood outbound off ramp are funded by the South Australian Government under the 2021-2022 Road Maintenance Program. Works involve removing existing pavement and replacing it with asphalt, to ensure the long term safety and integrity of the freeway for all road users.

    Times of works

    Works in the outbound lanes adjacent the Hahndorf/Woodside/Birdwood outbound off ramp are scheduled to commence on Sunday, 29 May 2022, and will take approximately one week to complete, weather permitting.

    Please see the map over the page outlining the location and details of the work.

    In order to minimise the impact to road users, the works will be undertaken at night between 7pm and 6am, Sunday to Friday. No works will be undertaken on Saturday nights.

    What to expect

    During works speed and lane restrictions will be in place through the work zone for outbound traffic.

    The Hahndorf/Woodside/Birdwood outbound off-ramp will be closed at night during the work period. Speed and lane restrictions will be in place with a detour via the Bridgewater Interchange outbound off-ramp, Carey Gully Road, Mount Barker Road, to Hahndorf/Woodside/Birdwood.

    Outside of work hours all lanes on the freeway and the Hahndorf/Woodside/Birdwood outbound off ramp will be open to traffic, with a 60km/h speed restriction in place.

    Access for buses and emergency service vehicles will be maintained at all times.

    Variable Message Signs will be in place at key locations to provide early notice to motorists of the traffic restrictions and detours.

    Motorists should expect delays, so please plan ahead and allow additional travel time. Please take extra care when workers are on site. Observe signage and speed limits, lane restrictions and traffic controllers when travelling through the area.

    Some noise disturbance can be expected at times while these works are completed, however, the work will be managed to minimise disturbance as much as practically possible. You may also notice some odour which is common when asphalting works are underway.

    Speed restrictions will remain in place for approximately four to six weeks on the newly resurfaced section of road, this is to enable excess bitumen on the new surface to be worn to a safe level. The posted speed limit will then be reinstated once it is safe to do so.

    The Department appreciates your patience and cooperation while these important works are undertaken
