The project will provide a freight route, which can safely accommodate Higher Productivity Vehicles (HPV’s) up to 26.0 metre B‑double and Performance-Based Standards Level 2A (PBS L2A) heavy vehicle combinations.

The works on the freight route include:

  • junction upgrades to enable HPV’s to undertake safe turning movements;
  • upgrade of existing culverts and bridge structures;
  • safety improvements including road widening, shoulder sealing, hazard protection and vegetation removal; and
  • upgrading Slow Vehicle Turnouts.
