Princes Highway, Pakenham to Longwarry North

We’re improving safety along the Princes Highway, between Cardinia Road in Pakenham to the Bunyip River in Longwarry North, as part of Towards Zero.

Infrastructure plays a vital role in keeping you safe, which is why we're installing a range of new technologies and proven safety features on roads across the state.

By installing these safety features and improving existing infrastructure, we can prevent serious crashes from happening, or reduce the severity of crashes when they are unavoidable.

Project update

Construction of this project is planned to commence late this year and will continue through to mid-2020. We will provide more details about traffic management closer to the beginning of construction.


The Princes Highway is the main freeway linking Melbourne to Gippsland. It is an important freight corridor supporting our agriculture, timber and mining industries, and a popular route for tourist travelling from Melbourne to Gippsland and on to southern New South Wales.

Between 2013 and 2017, there were 26 people who suffered serious injuries along this stretch of road and two people who tragically lost their lives.   

We’re improving safety between Pakenham and Longwarry on the Princes Highway now, to build a future where no-one is seriously injured or killed on our roads. 


Flexible safety barriers are already in place along sections of the road.

As part of this project we will be installing additional barriers flexible safety barriers on the centre median and left-hand side of the road in high-risk locations, providing a continuous safer corridor from Melbourne to the border of New South Wales to reduce the risk of head-on and run-off-road crashes.  

This project is planned to be completed by 2020.

Working with Major Roads Projects Victoria

Intersecting project: Monash Freeway Upgrade

Major Road Projects Victoria are upgrading the Monash Freeway between Warrigal Road in Chadstone and Cardinia Road in Pakenham. Stage 2 of their works, between Soldiers Road and Cardinia Road on the Princes Freeway, began in October 2018 and is expected to be completed by 2022. 

The Monash Freeway upgrade ends where the Towards Zero Princes Highway safety improvements begin, at the intersection with Cardinia Road. We are working with our partners at MRPV to ensure the timely delivery of both projects, and to mitigate cumulative travel impacts to the community.  

Have your say

We will be consulting with the local community on access requirements for landowners, businesses and emergency services.

Every effort will be made to minimise impacts to residents, motorists and the environment during the project.
