Details of Main South Road duplication stage two released

Dept of Infrastructure, Transport, Regional Development and Communications

The South Australian government has released details of stage two of the Main South Road duplication project, which will deliver on its election commitment to duplicate Main South Road from Aldinga through to Sellicks Beach.

The duplication has been funded jointly by the Australian and South Australian governments.

The duplication of Main South Road will result in safer, faster journeys for motorists and provide a vital boost for local tourism and communities, while supporting over 900 jobs each year during construction.

The concept design and new animation showing how the final project will come together have now been released for community feedback.

Stage two of the project will include the realignment of Aldinga Beach Road intersection and Sellicks Beach Road intersection.

To improve traffic flows, stage two will include an underpass at the intersection of Main South Road with the newly re-aligned Aldinga Road and Aldinga Beach Road. Two U-turns will also be installed to facilitate local access in addition to the Aldinga interchange.

Intersection upgrades will also be undertaken at Hart and Colville Roads, Norman and Rogers Roads, and Hahn and Cox Roads.

The project will also see the installation of wide centre medians, wire rope safety barriers to separate northbound and southbound traffic, with some removal of vegetation necessary to improve sight distances and allow for increased road width.

Feedback on the concept design is open until Friday 3 February 2023. You can view the design and video, and provide your feedback, at the South Australian Department for Infrastructure and Transport website.

Early work is expected to commence in mid-2023, with major construction expected to begin in late 2023.

Quotes attributable to Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King:

“Good infrastructure investment creates jobs, builds opportunity and unlocks economic growth and productivity.

“From the city to the country, our Government is committed to playing its role in helping to build a better future for all Australians.

“This is another example of the Australian Government working collaboratively with the SA Government to deliver the projects that will make a real difference to the lives of South Australians.”

Quotes attributable to Minister for Infrastructure and Transport Tom Koutsantonis:

“This is such an important project, so I am very pleased to see plans coming ahead for the next stage. Anybody who’s been through the area recently will have seen how hard the crews continue to work and that hard work will continue.

“We’ve released a new video showing how this stage will look once it comes together, and we’re looking forward to reviewing the community’s feedback on the concept design.

“The roads in this region connect so many important districts – the Fleurieu and its key tourist and beach areas, the McLaren Vale wineries and of course numerous growing communities. Ensuring safe connection and accessibility will allow this region to continue to thrive.

“As work continues, we ask anybody driving through the area to allow extra time, plan ahead and always drive to conditions.”

Quotes attributable to State Member for Mawson Leon Bignell:

“This is a key project for this region, which will make it easier for local, interstate and overseas tourists to get from the mainland to Kangaroo Island, as well as facilitating better freight movement.

“From 2024 we will have bigger Kangaroo Island ferries doing more daily crossings from Cape Jervis.

“For people working in the city this means they’ll have more time with their families and less time stuck in traffic.

“The Liberals delayed and downgraded this project in government – Labor is keeping its promise and getting on with the job of building infrastructure which will serve us well for decades to come.”
