South Australian Rural Highway Corridor Upgrades

In 2020, The Australian and South Australian Governments committed $1.1 billion to upgrade South Australia’s rural highway corridor. This represents the largest ever rural road investment for South Australia and includes upgrades to the Princes Highway Corridor, Horrocks Highway, Sturt Highway, Barrier Highway, Eyre Highway and Eyre Peninsula Roads.

Combined, these corridors make up approximately 2,400km, or just under 20 per cent, of South Australia’s 12,600km sealed regional road network. This unprecedented investment aims to:

  • Provide a more reliable and safe road network
  • Improve access for high productivity freight vehicles
  • Better connect rural communities
  • Facilitate economic growth
  • Enhance tourism opportunities in rural South Australia.

Funded projects include:

  • Sturt Highway
  • Barrier Highway
  • Eyre Highway and Eyre Peninsula Roads

Princes Highway Corridor

The $250 million Princes Highway Corridor program covers proposed works from the SA/Victoria border (near Mt Gambier) through Millicent, Coorong, Tailem Bend to Mount Barker, then along the Port Wakefield and Augusta Highway from Virginia to Port Augusta.
