Princes Highway Corridor Program

A funding commitment of $250 million has been made to upgrade infrastructure at locations along the Princes Highway Corridor in South Australia. The Princes Highway Corridor in South Australia is approximately 700km long and runs from the Victorian border east of Mount Gambier, all the way through to Port Augusta in the state’s North.

The corridor funding is for the rural segments and includes the Princes Highway (South East), South Eastern Freeway (Murray Bridge to Adelaide), Port Wakefield Highway (Virginia to Port Wakefield) and Augusta Highway (Port Wakefield to Port Augusta).

This funding has been made available due to the Australian Government’s Princes Highway Corridor Strategy. Further information about the Princes Highway Strategy can be found here.
