Status

Works underway.

Location

Sections of Eyre Highway, Stuart Highway and Olympic Dam Highway.

Funding

$75 million from Australian and South Australian governments (80:20) over four years.

About the project

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

This 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 these flood impacted areas:

• Eyre Highway – west of Kimba
• Stuart Highway – Glendambo, Woocalla Creek and Lake Windabout
• Olympic Dam Highway.

What's happening

These works will:

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

Project 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. Starting 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. It starts 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. It starts at Pimba and extends approximately 93 kilometres to Olympic Dam via Woomera and Roxby Downs.
