Fleurieu Connections

The Australian and South Australian governments have committed a total of $560 million to fund the Fleurieu Connections Main South Road and Victor Harbor Road duplication projects, to be delivered by the Fleurieu Connections Alliance. The Alliance is a consortium comprising CPB Contractors, Aurecon and GHD, with Sub-Alliance partners McMahon Services Australia and Tonkin, in association with the Department for Infrastructure and Transport (the Department). These projects will result in safer and faster journeys for motorists and provide a vital boost for local tourism, communities and support hundreds of jobs each year during construction.

Final Design

Following extensive consultation, traffic modelling and technical analysis, the State Government has endorsed the final design solutions, being:

Main South Road

Stage 1

Duplication of Main South Road, from Seaford to Aldinga, including a grade separation (overpass) at the intersection of Tatachilla Road and Maslin Beach Road, a grade separation at the intersection of Port Road and a grade separation and road alignment at the intersection of Main South Road and Aldinga Road, removing the planned roundabout at Aldinga Road.

Stage 2

Duplication of Main South Road, from Aldinga to Sellicks Beach will be delivered, restoring an additional lane for the project. A concept design is currently being developed and will be released to the community in the coming months. There will be an opportunity for community to provide input once the design has been developed.

Victor Harbor Road

Victor Harbor Road, between Main South Road and the McLaren Vale turn off, will be duplicated with additional safety treatments along Victor Harbor Road (including an overtaking lane at Hindmarsh Valley).

In addition, a planning study to investigate the preferred solution for Victor Harbor Road between Main Road, McLaren Vale and Tatachilla Road and to Willunga Hill will be undertaken.

Summary of community and stakeholder feedback received

We would like to thank the community and interested stakeholders who have engaged with us to date about these important projects. Around 130 people attended the Community Information Sessions held in late April 2021, and nearly 900 survey responses were received. We also met individually with a number of stakeholders and received direct feedback to the Department.

Common themes raised during the consultation the concept designs, between March and May 2021, included:

  • a strong level of support for duplication of Main South Road, between Seaford and Aldinga, and for a grade separation at the intersection with Tatachilla Road;
  • considerable feedback about the functioning of the current single lane roundabout at Port Road and Main South Road and requests for it to be replaced with a grade separation;
  • mixed views on the duplication between Aldinga and Sellicks Beach. Common feedback at the Community Information Sessions was that duplication south of Aldinga wasn’t critical and may negatively impact the character of the area. Other treatments to improve the safety of the area were however important. The undulating nature of Main South Road, particularly north of Norman Road, was also consistently raised;
  • the importance of minimising the impact to vegetation;
  • the importance of east-west connections being maintained, particularly for emergency services, agriculture machinery, pedestrians and cyclists; and
  • the importance of minimising disruption during construction.

Next Steps and Project Timeframe

Works are planned to commence in late 2021 and be completed in 2024. Site investigation activities, and further engagement with the community, will continue to be carried out to inform the detailed design.

DIT COVID-19 Response

The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities.

Face-to-face engagement opportunities may be restricted and we will continue to be guided by the advice of health authorities, with the health and safety of our stakeholders always our highest priority.

Engagement with community and industry is crucial and we will facilitate information sessions as much as possible to enable face to face engagement. It is important to assist in managing these events that you register as requested to enable physical distancing as much as possible
