Project description

The Port Augusta to Perth corridor is approximately 2,388km long and comprises the Eyre Highway, Great Eastern Highway and Coolgardie-Esperance Highways.

The key arterial roads connecting to the corridor include the Esperance Highway and the Albany Highway in WA and the Flinders Highway and Augusta Highway in SA.

The project will include targeted upgrades to widen, strengthen and realign various sections of this corridor to improve the flow of vehicles and increase access for higher efficiency heavy vehicles.

The following projects are being delivered for the WA section of the corridor -

  •  Port Augusta to Perth (WA) - Coolgardie-Esperance Highway - Emu Rocks
  •  Port Augusta to Perth (WA) - Great Eastern Highway - Walgoolan Southern Cross and Coates Gully



These projects will:

  • Improve road safety
  • Improve freight efficiency, connectivity and travel time
  • Ensure consistent Restricted Access Vehicles (RAVs) ratings across the network, which will provide improved access for agricultural and mining regions to transport hubs


The Australian Government has committed $74 million towards the WA section of the corridor.


The two WA projects are currently under construction and are expected to be completed by early 2023.
