The Augusta Highway Overtaking Lanes Project is jointly funded (80:20) by the Australian and South Australian Governments as part of the South Australian Rural Roads Safety Package.

The Augusta Highway is the key corridor between Port Wakefield and Port Augusta and forms part of the National Land Transport Network, providing crucial connectivity to regional South Australia and interstate.

The project includes construction of two overtaking lanes along Augusta Highway:

• southbound between Lake View Road and Damascus Road, south of Redhill; and
• southbound between Maro Creek Lane and Diagonal Road, north of Lochiel.

The overtaking lane near Lochiel was completed and opened to traffic in March 2023, and the one near Redhill is nearing completion.

The project will also involve refurbishment of the sections of the existing Augusta Highway, adjacent the overtaking lanes.
