The South Australian Government has released the concept design for stage two of the Main South Road Duplication, along with a new animation showing how the final project will come together.
The duplication is expected to result in safer, faster journeys for motorists and provide a boost for local tourism and communities, while supporting more than 900 jobs each year during construction.
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 include 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.
The project comes as part of the $685 million Fleurieu Connections Main South Road and Victor Harbor Road duplication projects, which are jointly funded by the Federal and South Australian governments.
The projects are being delivered by the Fleurieu Connections Alliance, which comprises CPB Contractors, Aurecon, and GHD, with Sub-Alliance partners McMahon Services Australia and Tonkin, in association with the Department for Infrastructure and Transport.
Early work is expected to commence in mid-2023, with major construction due to begin in late 2023.
Feedback on the concept design is open until Friday 3 February 2023
