Stage 2 of Main South Road duplication is close to beginning construction
The second stage of the Main South Road duplication in South Australia is a step closer to beginning major construction following the release of the project’s final design.
Meanwhile, Stage 1 of the Main South Road duplication between Seaford and Port Road in Aldinga is now complete.
Stage 2 works will cover the section of Main South Road between Aldinga Beach Road and Sellicks Beach.
“The feedback from the community has been positive and locals are excited to finally see works starting on Stage Two.
“Labor had a resounding success by taking to the 2022 state election a four-lane, no roundabout plan that aligns Aldinga Beach Road and Aldinga Road and allows non-stop north-south traffic.
“We listened to locals and are giving them a safe, efficient road that will serve visitors and locals for decades to come,” Member for Mawson Leon Bignell said.
Project scope includes:
- 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 Roger roads, and Hahn and Cox roads
- Installation of wide centre medians, wire rope safety barriers to separate northbound and southbound traffic
- A Shared Use Path (SUP) along the western side of Main South Road
This project is expected to be completed in 2026 and is estimated to support about 405 full-time equivalent jobs annually during the construction phase.
“All four lanes of Stage One of the Main South Road duplication have opened to traffic – and now we’re getting on with our election commitment to duplicate the road all the way to Sellicks Beach.
“Around 17,000 vehicles travel on Main South Road every day. Continuing the duplication will improve safety and travel times for motorists, while also improving road and network connectivity to support regional growth and tourism across the Fleurieu Peninsula.
“Following feedback from those who love, work and travel in the region, we’ve updated the design of Stage Two to ensure it delivers the best outcome for all road users.
“We’ve added in an additional U-turn, improved pedestrian access at Sellicks Beach and modified the Aldinga interchange to improve connectivity,” Minister for Infrastructure and Transport Tom Koutsantonis MP said.
Stage 2 of the Main South Road duplication is part of the $810.4 million Fleurieu Connections project that is jointly funded by the Australian and South Australian Governments.
