About the project
We are delivering upgrades to the Augusta Highway to improve safety and reliability for all road users.
These upgrades will improve freight productivity by reducing travel times for delivering goods to businesses and the community, as well as reducing operating costs for commercial vehicles.
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 upgrades will take place over 10 years, starting in 2023. It will include intersection upgrades, new overtaking lanes, and targeted safety treatments.
