Fleurieu Connections

The Australian and South Australian governments have committed $560 million to jointly fund the Main South Road and Victor Harbor Road duplication projects, to be delivered by the Department for Infrastructure and Transport (the Department).

Concept designs have been developed for Stage 1 of the Main South Road Duplication Project, between Seaford and Aldinga and for the Victor Harbor Road Duplication Project, between Main South Road and Main Road, McLaren Vale

The concept designs for both projects have been developed to encompass project objectives, design criteria, community and stakeholder feedback to date and the outcomes of environmental, social, safety, economic and preliminary site investigations.

The Department invites you to provide feedback on two scenarios currently being considered to assist in informing decisions around the overall delivery and funding allocation for these projects.

SCENARIO 1 – TWO LANE ROUNDABOUT SOLUTION

  • Duplication of Main South Road, Stages 1 and 2 from Seaford to Sellicks, including dual lane roundabouts at the intersection of Tatachilla Road/Maslin Beach Road, Port Road and Aldinga Road.
  • Duplication of Victor Harbor Road, between Main South Road and Main Road, McLaren Vale.

SCENARIO 2 – NORTH-SOUTH OVERPASS SOLUTION

  • Duplication of Main South Road, Stage 1, from Seaford to Aldinga including a grade separation at the intersection of Tatachilla Road/Maslin Beach Road, and dual lane roundabouts at Port Road and Aldinga Road.
  • Upgrade of Stage 2, from Aldinga to Sellicks, to address safety and future capacity of Main South Road.
  • Extend Victor Harbor Road duplication from Main South Road past Main Road, in McLaren Vale to Tatachilla Road to a proposed posted speed limit of 100km/h.

SCENARIOS AT A GLANCE

Community feedback, in addition to other criteria such as project objectives, road safety, design, engineering, economic, cultural and environmental investigations, will help inform how the Department progresses the design and delivery of these projects.

A decision can then be made on the scenario which will provide the best possible outcome for the public overall.

Feedback on all aspects of the concept designs for Main South Road Duplication Stage 1 and Victor Harbor Road Duplication is now sought. Concept design for Main South Road Duplication Stage 2 will commence this year.

Community Information Sessions

The project team held Community Information Sessions at McLaren Vale and Aldinga in the week commencing 19 April.  The community was invited to drop into any of these to view the concept designs, speak to members of the project team, learn more about the projects, ask any questions and provide us with feedback.

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.
