We’re adding extra lanes and building new intersections along the Princes Highway between Winchelsea and Colac to make your journey quicker and safer.


In 2015, we started adding extra lanes on the Princes Highway between Winchelsea and Colac.

This project is building more than 35km of extra lanes and new intersections.

The upgrade will be separated into four stages:

  • Deans Marsh Road, Winchelsea to Armytage Road
  • Armytage Road to Warncoort
  • Warncoort to Colac East
  • Colac East and Colac.

We expect to complete the upgrade in 2019.
