SA Freight Highway Upgrade Program

The Australian and South Australian governments have committed $500 million (80:20) over 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.

We are undertaking pavement rehabilitation works and road widening on the Stuart Highway and Augusta Highway at multiple locations between Yorkeys Crossing Road and Northern Power Station Road. For more information, including a project map, please view the latest works notice.
