Project Description

The Port of Portland is the largest hardwood chip exporter in the world, with hardwood grown in the Green Triangle accounting for 4.5 million tonnes of woodchips exported annually. However, the roads in south-west Victoria were not designed for the heavy freight vehicles currently using them. The project is expected to deliver road upgrades across the Green Triangle region of south-west Victoria, with a focus on four key arterial road corridors that provide freight connections to the Port of Portland:


  • Portland-Casterton Road
  • Henty Highway
  • Portland-Nelson Road
  • Princes Highway West.

These works will support growing industries in the region by providing improved access for High Productivity Freight Vehicles and improving the safety and efficiency of the road network.

Works in Tranche 1 will include:

  • Bridge Upgrades - The Australian Government is committing $9.4 million towards bridge upgrades at Grange Burn, Charcoal Creek and Wattle Hill Creek to improve access and safety for High Productivity Freight Vehicles.
  • Road Surface and Intersection Upgrades - The Australian Government is committing $7.4 million to undertake a number of road surface upgrades to key routes within the Green Triangle region. 
  • Scoping and development - The Australian Government is committing $0.4 million for scoping and development works to inform projects for delivery in future tranches. 


  • Improved road safety for all road users
  • Improved connectivity between people with jobs and services, and goods with markets
  • Improved accessibility and connectivity of road networks


The Australian Government is contributing $100 million towards this $125 million project.

This includes additional funding of $25 million announced in the 2021-22 Budget.

The remaining $82 million of Australian Government funding will be allocated to future priorities along the corridor. 


Scoping and development works for the corridor commenced in mid-2021. Road surface and intersection upgrades under Tranche 1 began in late 2021, with the remained expected to commenced in early 2022.
