The Port Augusta (South Australia) to Perth (Western Australia) corridor is approximately 2,388 km long and comprises the Eyre Highway, Great Eastern Highway and Coolgardie-Esperance Highway. The project will widen, strengthen and realign various sections along the corridor.

In addition to upgrades along the Eyre Highway, roads across the Lower Eyre Peninsula will be upgraded as part of the Eyre Peninsula Network project to cater for future freight movements in the region.

Upgrades along this section of Eyre Highway and the Lower Eyre Peninsula roads could include:

  • new overtaking lanes
  • road widening and shoulder sealing
  • rest areas for improved fatigue management
  • pavement rehabilitation
  • safety measures such as audio tactile line marking, improved signs and hazard protection
  • intersection and roundabout improvements
  • bridge upgrades.

Key investigations underway:

  • New overtaking lanes – to improve safety for freight and commuter vehicles bound for Port Lincoln. New lanes on Lincoln Highway (Tumby Bay to Louth Bay), Tod Highway (South of Cummins), Western Access Road (New West Road to Pine Freezers Road) and  Flinders Highway (extension of acceleration lane at the Tod Highway junction) are priority locations.
  • New overtaking lanes – to improve capacity between the major regional towns as well as safety due to high traffic volumes on Eyre Highway directly west of Port Augusta, new overtaking lanes between Port Augusta airport to rail overpass are priority locations.
  • Intersection improvements – to address constraints due to the tight turn movements for freight vehicles over the rail crossing at the western end of Kimba, a road realignment is proposed (possibly including new rest area for freight and passenger traffic). This could reduce the need to use the over-dimensional route.
  • Intersection improvements – to address multiple locations near and within Ceduna to improve safety. Locations include the junctions of Eyre Highway with McKenzie Street, and Eyre Highway with Flinders Highway.
  • Shoulder sealing – to provide a consistent seal width for improved safety along Tod Highway (Flinders Highway to Lock) and Birdseye Highway (Rudall to Cleve). Early works have been completed on Birdseye Highway (Cowell to Cleve) and Lincoln Highway (Lucky Bay to Birdseye Highway).
  • Roundabout improvements – In response to safety concerns raised with uncontrolled pedestrian movements across Lincoln Highway, layout upgrades to the traffic and existing crossing points on existing roundabouts in Port Lincoln CBD
