Exciting progress is underway on the Fleurieu Peninsula, as safer, smoother journeys start to take shape with the new bridge, part of the new Aldinga interchange, on track to open in early 2025. The bridge opening will mark a turning point for local travel, introducing enhanced connections and improved safety for road users.

Completion of the bridge works and the introduction of temporary traffic signals to guide drivers efficiently through the area will mark another major milestone for the project. These temporary signals installed at the new Main South Road, Aldinga Road and Aldinga Beach Road intersection will ensure a safer and more predictable flow of traffic until the full interchange opens in 2026. The realignment of Aldinga Beach Road and Aldinga Road creates a safer and seamless network that will keep traffic flowing and improve motorist safety in the area.

Temporary traffic signals will be in place for traffic on Main South Road and for motorists turning left onto this major roadway. While some delays may be experienced while these temporary arrangements are in place, these carefully planned measures will optimise safety and movements for all during this transition phase. When the lowered motorway is opened to traffic, these temporary signals will be removed, allowing uninterrupted travel through this area. Work on this key infrastructure project began in mid-2024, with all works expected to be fully complete in 2026.

Piling work for the bridge has also been completed, with 53 sturdy piles forming its foundation. The abutments, which transfer the load into these piles, will soon carry twelve concrete beams, each weighing 40 tonnes, set to be installed later this year. The underpass excavation is also progressing, with an incredible 70,000 cubic metres of soil to be removed for the future four-lane roadway that will guide Main South Road traffic smoothly beneath the new bridge.

As part of these works, advanced engineering techniques like soil nailing and shotcrete are being employed. By the project’s end, 15,600 metres of soil nails and 4,000 square metres of shotcrete will support the underpass, providing long-term stability and safety.

As the opening of the bridge approaches, the Fleurieu Peninsula edges closer to a new era of connectivity. This project is more than just a road upgrade; it’s a transformation that promises safer journeys, stronger community ties, and a more efficient travel experience for years to come.
