Flood Recovery - Targeted Investment to Improve National Supply Chain Resilience

Commencing in 2022-2023, the Australian and South Australian governments have committed $75 million (80:20) over four years to fund the Targeted Investment to Improve National Supply Chain Resilience program.

In January 2022, intense rain events and subsequent flash flooding across the Eyre Highway and Stuart Highway caused extensive damage to large sections of the State’s national highways, impacting the transport of essential supplies, commodities and services to the community and industry.

The Targeted Investment to Improve National Supply Chain Resilience program focusses on flood recovery and improving the flood resilience of these important highways in the far north.

The program includes upgrades to flood impacted areas and includes the Eyre Highway (west of Kimba), Stuart Highway (Glendambo, Woocalla Creek and Lake Windabout) and Olympic Dam Highway.

Background

The Eyre Highway is the primary road link between South Australia and Western Australia, supporting a high proportion of interstate and intrastate heavy vehicles. Commencing at the Western Australia border, the South Australian section of the road extends approximately 945 kilometres to Port Augusta.

The Stuart Highway is the primary road link between South Australia and the Northern Territory, linking Port Augusta to Darwin. Commencing at the Northern Territory border, the South Australian section of the road extends approximately 924 kilometres to the south in Port Augusta.

The Olympic Dam Highway is a primary road link in the outback, commencing at Pimba, and extending approximately 93 kilometres to Olympic Dam via Woomera and Roxby Downs.

The Stuart Highway (Glendambo and Lake Windabout), and Eyre Highway (west of Kimba) are in the design phase, with final design expected at the end of 2023.

Works will raise the level of the existing road surface to mitigate the chance of water overlapping and closing the road. Works will include an increase in the number of drainage structures, provide scour protection and rock armour along the batter slopes.
