Overview
We’ve widened this key arterial route from 2 to 4 lanes, making the 35km journey quicker and safer for up to 13,000 drivers every day.
The new highway has:
- new intersections
- two new bridges over the Geelong-Warrnambool train line – 1 of which removed a dangerous level crossing
- a new bridge over Barongarook Creek in Colac
- more than 120km of new safety barriers.
In 2015, we started adding extra lanes on the Princes Highway between Winchelsea and Colac. Sections were opened as they were completed.
We separated the upgrade into 4 stages:
- Deans Marsh Road, Winchelsea to Armytage
- Armytage to Warncoort
- Warncoort to Colac East
- Colac East and Colac (including Barongarook Creek).
