Augusta Highway Duplication

Project Overview

The Australian and South Australian governments have committed $260 million (80:20) to the Augusta Highway Duplication Project. This includes the duplication of the Augusta Highway from Port Wakefield to Lochiel.

The Augusta Highway is the key road 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 key benefits of this project include:

  • improved road safety for all road users;
  • improved freight productivity;
  • reduced travel times; and
  • improved efficiency and network reliability.

The PW2PA Alliance has been engaged by the Department for Infrastructure and Transport to deliver the highway duplication between Port Wakefield and Lochiel.

The project is expected to be completed in 2024.
