Details of Main South Road Duplication stage two released

Thursday, 19 January 2023

Details of stage two of the Main South Road duplication project have been released.

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.

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