Project Description

The Port Augusta (South Australia) to Perth (Western Australia) corridor is approximately 2,388km long and comprises the Eyre Highway, Great Eastern Highway and Coolgardie-Esperance Highway. The project will widen, strengthen and realign various sections along the corridor.


Targeted upgrades will increase access for higher efficiency heavy vehicles, leading to an overall increase in the efficiency of the corridor in line with the ROSI objectives. Key industries that will benefit from an upgrade to this corridor include, grain, fuel and livestock.


The Australian Government has committed $150 million towards the Port Augusta to Perth Corridor, of which $100 million has been committed to South Australia and $50 million to Western Australia.


Construction is expected to commence in late 2020 and be complete by 2022.
