Stage 2 of Main South Rd duplication in SA marks new project milestone

A new major milestone has been reached on the Main South Road Duplication Project in South Australia with the release of the details for Stage Two. 

The second stage of the project will duplicate the road from Aldinga through to Sellicks Beach to provide safer and faster journeys for motorists while also delivering a vital boost to local tourism and communities. 

“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. 

“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,” SA Minister for Infrastructure and Transport Tom Koutsantonis said. 

The community is encouraged to have their say on the released concept design and new animation that shows how the final project will look. 

Stage Two of the Main South Road Duplication Project will include realigning the Aldinga Beach Road intersection and Sellicks Beach Road intersection. 

The construction of an underpass at the intersection of Main South Road with the newly re-aligned Aldinga Road and Aldinga Beach Road will also be included to help improve traffic flow. In addition to the Aldinga interchange, the project will also include the installation of two U-turns to facilitate local access. 

Other works will include upgrades at Hart and Colville Roads, Norman and Rogers Roads as well as Hahn and Cox Roads. 

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

“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,” State Member for Mawson Leon Bignell said. 

Feedback on the project's concept design can be submitted until 3 February 2023 and more information on the Main South Road Duplication Project Stage Two can be viewed here. 

Stage Two is anticipated to support more than 900 jobs annually during its construction phase. 

The Australian and South Australian Governments have jointly committed $685 million towards the Fleurieu Connections Main South Road and Victor Harbor Road duplication projects, which will be delivered by the Fleurieu Connections Alliance – comprised of CPB Contractors, Aurecon and GHD, with Sub-Alliance partners McMahon Services Australia and Tonkin. 

“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 projects that will make a real difference to the lives of South Australians,” Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King said. 

Early works on this project is expected to begin in mid-2023 and major construction to commence in late 2023.
