CPB Contractors appointed to deliver Main South Rd Duplication Stage 2

The South Australian Government has chosen CPB Contractors – a CIMIC Group company and as part of the Fleurieu Connections Alliance – to undertake the delivery of the Main South Road Duplication 2 (MSRD2) Project. 

This contract award will generate revenue of about $200 million for CPB Contractors and will include the delivery of a six-kilometre duplication road between Aldinga Road and Sellicks Beach Road south of Adelaide. 

“CPB Contractors has the experience to safely and reliably deliver the Main South Road Duplication 2 Project. This is a significant productivity enhancing project for regional South Australia that will ensure a safer and faster journey for motorists, while providing a vital boost for local tourism,” CIMIC Group Executive Chairman Juan Santamaria said. 

“We’ll be drawing on our 90-plus years’ experience delivering complex road infrastructure as well as our local relationships and knowledge working on the Main South Road and Victor Harbor Road duplication project. Together with the Department of Infrastructure and Transport and our Alliance partners, we look forward to continuing to engage with local people, suppliers and businesses to ensure we maximise economic, employment and social opportunities for the community,” CPB Contractors Managing Director Jason Spears said. 

The second stage of the Main South Road Duplication includes: 

• The realignment of Aldinga Beach Road intersection and Sellicks Beach Road intersection 

• An underpass at the intersection of Main South Road with the newly re-aligned Aldinga Road and Aldinga Beach Road 

• Two U-turns to facilitate local access in addition to the Aldinga interchange 

• Key intersection upgrades at Hart and Colville roads, Norman and Rogers roads, and Hahn and Cox roads 

• Installation of wide centre medians, wire rope safety barriers to separate northbound and southbound traffic 

• A Shared User Path (SUP) along the western side of Main South Road 

Construction is due to be completed in 2026, supporting up to 405 full-time equivalent jobs. 

The Australian and South Australian Governments have jointly committed a total of $810 million towards the Fleurieu Connections project, which is being delivered by the Fleurieu Connections Alliance.
