$25m for major works to repair the Outback Highway

Monday 25 August 2025

Works have commenced today on a $25 million project to repair damage to The Outback Highway between Lyndhurst and Marree caused by flooding associated with Cyclone Tiffany.

The Australian and South Australian Governments are jointly funding the works through the Commonwealth-State Disaster Recovery Funding Arrangements.

Importantly, the project will make the road more resilient to future flooding, benefiting and maintaining the vital connection for regional mining, primary and tourism industries and remote communities.

Assessments have been conducted to identify how improvements to the section of highway that was inundated during the major flood event can be incorporated as part of the repair works to improve resilience to future flooding events.

This includes raising the road profile, and new and improved drainage as the road is reconstructed.

Procurement for the works has been completed, and the project will be managed and delivered by South Australia’s Department for Infrastructure and Transport.
