South Australia’s new Aldinga Bridge has opened to traffic this week, marking a major milestone for the duplication of Main South Road between Aldinga and Sellicks.
The Aldinga Bridge is a key feature of the new Aldinga Interchange, which realigns the junctions of Aldinga Beach Road and Aldinga Road to create a safer and more efficient connection. Traffic is now also travelling on parts of the newly constructed northbound carriageway on Main South Road.
As well as the Aldinga Interchange, the stage 2 Main South Road duplication includes intersection upgrades at Hart and Colville roads, Norman and Rogers roads, Hahn and Cox roads and Sellicks Beach Road, as well as the installation of wide centre medians and wire rope barriers to improve safety by separating northbound and southbound traffic.
It also includes three U-turns to facilitate local access and a shared use path for pedestrians and cyclists along the western side of Main South Road, from Aldinga to Sellicks Beach.
Stage 2 of the Main South Road duplication between Aldinga Beach Road and Sellicks Beach is being delivered as part of the $810.4 million Fleurieu Connections project, funded by the South Australian and Australian governments.
It is due for full completion in 2026.
Temporary traffic signals will be in place at the new Main South Road, Aldinga Road and Aldinga Beach Road intersection from Monday March 3 to help ensure a safer and more predictable flow of traffic until the full interchange opens in 2026, when Main South Road traffic will be sent under the new bridge.
