Port Wakefield to Port Augusta Alliance
The Port Wakefield to Port Augusta (PW2PA) Alliance has successfully delivered a suite of major regional infrastructure projects that are now complete and open to traffic. Working in collaboration with the South Australian Department for Infrastructure and Transport, the PW2PA Alliance, comprising CPB Contractors, Aurecon and GHD, has delivered transformative upgrades to critical freight and commuter routes in the state’s north. These projects were designed to improve road safety, reduce congestion, and strengthen connections between regional communities, freight networks, and urban centres across South Australia.
Ongoing Maintenance Update - Augusta Highway
Our teams have identified some areas of pavement requiring further attention along the recently duplicated Augusta Highway. Temporary speed and lane restrictions are in place while we investigate and implement permanent repairs. We’re committed to delivering a safe and high-quality road and will continue to manage these works with care and minimal disruption.Our Projects
Joy Baluch AM Bridge Duplication
Construction of the Joy Baluch AM Bridge Duplication in Port Augusta began in early 2020. This significant infrastructure project involved duplicating the existing bridge to deliver two-way traffic movement across the Spencer Gulf, along with the addition of a shared-use path for pedestrians and cyclists. The project has vastly improved safety and connectivity between the eastern and western sides of Port Augusta, while reducing traffic congestion and improving freight efficiency. The duplicated bridge officially opened to traffic in June 2023.| Construction Commenced | Construction Completed |

Port Wakefield Overpass and Highway Duplication
Work commenced on the Port Wakefield Overpass and Highway Duplication in late 2020. This project involved constructing a grade-separated overpass, duplicating the highway through Port Wakefield, and upgrading key intersections. It addressed a well-known traffic bottleneck and significantly improved traffic flow and safety along this critical corridor. With these upgrades, the risk of head-on and intersection collisions has been reduced, and freight and commuter travel has become more efficient. The overpass and duplicated highway were opened to traffic in April 2022.| Construction Commenced | Construction Completed |

Port Augusta Swimming Pontoon
Construction of the new swimming pontoon at the Port Augusta foreshore began in late 2024. Designed as a community and recreational asset, the pontoon enhances public access to the Spencer Gulf and creates a new space for residents and visitors to enjoy water-based activities. The project was completed in March 2025 and handed over to the local council, just in time for the South Australian Masters Games in April. It represents a lasting legacy for the community and a boost for local tourism.| Construction Commenced | Construction Completed |

Augusta Highway Overtaking Lanes
Construction of new overtaking lanes on the Augusta Highway began in late 2022, as part of efforts to enhance overtaking opportunities and improve road safety. The project included two new overtaking lanes; one near Lochiel, which opened to traffic in March 2023, and another near Redhill, opened in late 2023.

Augusta Highway Duplication
Construction of the Augusta Highway Duplication between Port Wakefield and Lochiel began in mid-2021. The project involved the duplication of approximately 28 kilometres of highway, providing a divided carriageway that separates opposing traffic flows. This upgrade has delivered substantial improvements in road safety, especially in reducing the risk of head-on collisions. It has also supported improved freight efficiency and strengthened the connection between regional centres. Major works on this section are complete, with the road returned to full speed on 31 March 2025.| Construction Commenced | Construction Completed |

Lower Eyre Peninsula Overtaking Lanes
Works to construct new overtaking lanes on the Lower Eyre Peninsula commenced in mid-2022. The project delivered four overtaking lanes on Lincoln Highway, Flinders Highway and Western Approach Road, north of Port Lincoln. These upgrades were a welcome improvement for road users, providing safer overtaking opportunities, reducing travel time, and supporting regional connectivity. All four lanes were opened to traffic during 2023.

Dublin Saleyards Access Upgrade
The Dublin Saleyard Access Upgrade commenced in early 2021, targeting improvements to road safety and traffic efficiency around the busy saleyard precinct. The project delivered upgraded access routes and intersection improvements that better accommodate high volumes of heavy vehicles and livestock transporters. These works have supported safer access to the saleyards, improved traffic flow during sale days, and enhanced the overall efficiency of freight operations. Construction was completed in September 2021.
