Green Triangle freight routes in south-west Victoria

We’re improving key freight routes within the Green Triangle network in south-west Victoria to promote safety and productivity over the next four years.

The Australian and Victorian governments have committed $40 million to upgrade key arterial roads in the Green Triangle region of south-west Victoria.

Henty Highway, Portland-Casterton Road and Portland-Nelson Road will be upgraded to provide safer and more efficient travel for community, tourists and freight operators.

The Australian and Victorian governments have also provided $40 million to upgrade the condition of Princes Highway between Colac and the South Australian border.

Project background

The Green Triangle spans about 6 million hectares in south-west Victoria.

There has been a significant increase in heavy vehicle traffic in this area through industries such as forestry, wind farms and mineral sands, and dairy production.

More than 100km of road will be improved to provide a much smoother and safer drive, as well as help preserve the roads for years to come.

About the project

So far, we’ve improved roads in the following locations:

Henty Highway

  • Rebuilt 2km of Portland Ring Road and the intersection at Madeira Packet Rd
  • Finished resurfacing Henty Hwy / Princes Hwy intersection near Portland and installed new drainage and rebuilt the highway at Maretimo
  • Rebuilt 13km and resurfaced 9km of highway between Heywood and Hamilton

Portland Nelson Road

  • Resurfaced 33km of roadway between Portland and the SA Border

Portland Casterton Road

  • Realigned and resurfaced the intersection with Glenelg Hwy
  • Placed a final surface on 25km of existing and previously rebuilt roadway between Casterton and Drumborg

Princes Highway

  • Rebuilt the Henty Hwy / Princes Hwy intersection near Heywood
  • Resurfaced intersections between Camperdown and Terang including Darlington Rd, Cross Forest Rd, Noogee Rd, Occupation Ln and Boorcann Rd
  • Rebuilt and resurfaced 9.6km from SA border to Mumbannar
  • Resurfaced Raglan Pde in Warrnambool between Liebig St and Glenrowe Av and rebuilt two sections of Main St in Terang


Rehabilitation of the road network leading to the Port of Portland will improve safety and reliability of freight routes and ensure they are strong enough to cater for future freight demands.

We’re making these roads fit for purpose, so they’ll be stronger, last longer and need less patching.

As we repair these roads, the new road surface will improve reliability and reduce wear and tear on buses, freight, and passenger vehicles.

Community involvement

Last year we visited Portland and Warrnambool; this year we started in March speaking with the Hamilton community; and are planning on visiting more regional towns this year.

You have helped identify some of our priorities, and when you see us return to the roads in spring, we will continue to be quite visible fixing the rural roads.

What happens next?

During the wet and cold winter months, we’ll continue investigating other sections of the road network, including surface inspections and taking samples. We’re focusing on preparing our program for the warmer months.

We regularly monitor and continue to maintain the roads, even if you don’t see us, to make sure the roads are safe. We want people to arrive safely at their destinations where and whenever they are travelling.

In the meantime, you can help us by reporting any hazards to the Traffic Management Centre on 13 11 70.
