We’re adding an extra lane, upgrading intersections and installing safety barriers in two stages between Princes Freeway and Manks Road.


Over two stages of the Healesville-Koo Wee Rup Road Upgrade, we’ll:

  • add an extra lane in each direction between Princes Freeway and Manks Road
  • widen the existing Princes Freeway ramps
  • install new traffic lights at Greenhills Road
  • build a new bridge over Deep Creek near the water recycling plant
  • install new roundabouts at Hall Road, south of Deep Creek and Ballarto Road
  • build a new shared walking and cycling path
  • add safety barriers along the road.


This upgrade will:

  • improve traffic flow and travel times
  • provide an upgraded alternative north-south route in the Pakenham South area
  • lower the risk and severity of crashes by adding safety barriers.

Project update

In mid-2020 we changed the delivery model of the Healesville-Koo Wee Rup Road Upgrade.

Instead of being delivered as a Public Private Partnership, with a group of other projects in the south, the Healesville-Koo Wee Rup Road Upgrade will be completed by dedicated contractor selected from a pre-approved panel.

The new streamlined approach will help shovel-ready projects get underway sooner, provide more certainty around timelines and give local construction companies more opportunities to win contracts and stimulate the local job market.

The change in delivery model has not impacted the original delivery timeframe, as both stages of the project will still be completed by 2025.

We anticipate appointing a contractor to work through a detailed planning phase of the first stage on the Healesville-Koo Wee Rup Road Upgrade in mid to late 2021.

This phase will include developing a detailed construction program. It will likely also involve site investigations such as locating utility services and getting a better understanding of road and ground conditions.

We expect to start constructing the Healesville-Koo Wee Rup Road Upgrade in the first half of 2022.
