Port Augusta junction upgrades

The Australian and South Australian governments have committed $500 million (80:20) over the next 10 years to improve the safety and reliability of national freight routes. This includes the upgrade of three major highways in South Australia.

More than 3,200 heavy vehicles a day use the Stuart, Augusta and Dukes highways, which are vital transport corridors for freight crossing the nation. About half of those vehicles are B-doubles and road trains. The upgrades will also improve freight productivity by reducing travel times for the delivery of goods to businesses and the community, as well as reducing operating costs for commercial vehicles.

As part of the program, the Department recently completed upgrades at the following junction in Port Augusta:

Stuart Highway and Madland Street; and
Stuart Highway, Eyre Highway and Augusta Highway.

The upgrades included pavement reconstruction, road resurfacing and new line marking. Road resurfacing was also undertaken on the section of Stuart Highway between both junctions. Works commenced on Tuesday, 13 June 2023 and were completed in August 2023.
