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


As part of the Princes Highway Upgrade in Colac and Colac East, we have:

  • built new intersections
  • added pedestrian crossings
  • added new road surfaces
  • upgraded traffic lights
  • upgraded the bridge over the Geelong-Warrnambool train line in East Colac.

In 2019, we'll:

  • replace the bridge over Barongarook Creek to cater for freight vehicles
  • upgrade walking and cycling routes
  • upgrade the entry to Colac
  • plant new vegetation.


To prepare the ground for construction we'll, unfortunately need to remove some trees and vegetation in line with our Environmental Management Plan. We're committed to minimising vegetation loss as much as possible. Tree protection zones and no-go zones will preserve sensitive sites.

We're working closely with Landcare, the Corangamite Catchment Management Authority, the Department of Environment, Land, Water and Planning and the Colac Otway Shire. Together, we'll develop a landscaping plan to ensure that once the project is complete, the area will be suitably revegetated. We're also working with the community to reuse vegetation we need to remove.


The contract has been awarded to VEC Civil Engineering.
