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.

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 started in January and is planned to be completed by mid-2020.

Project update

Construction of this project will begin on Monday 20 January and will continue through to July 2020, weather permitting. 

During January and February, crews will be working on the outbound lanes from Monday to Saturday between 6am and 6pm. During works you can expect to see:

  • A reduced limit of 40km/h through the worksite, to protect both workers and drivers
  • One lane closed while safety barrier installation takes place
  • An extra five minutes of travel time.

If you’re traveling through the area, please allow for an extra five minutes in your travel time, watch out for our crews and drive safely. 

Thank you for your patience while we complete these important safety upgrades.

Maintenance works on the Pakenham Bypass

We’ll be completing resurfacing works on sections of the Princes Freeway from 3 to 10 February between Koo Wee Rup Road and the Tynong Road. 

  • From 3 to 6 February, the outbound lanes will be closed between 7am and 4:00pm during works. Traffic will be detoured via Princes Highway. 
  • On the 6 and 10 February, there will be lane closures for inbound traffic between 9:30am – 4pm. There’ll be one remaining lane open during works, with reduced speed limits in place.

Please allow for an extra ten minutes when travelling through the area.

Emergency management

We’re working as part of a state-wide response to protect the safety of Victorians during this unprecedented emergency – and the management of roads in fire affected areas is a vital part of that.

While some projects in high-risk and fire impacted zones have been postponed, we are progressing priority safety projects in areas where there is no impact to emergency planning and responses. These safety projects are vital as part of our ongoing work to ensure everyone has a safe journey, by reducing the risk of head-on or run-off-road crashes.

To avoid impacts to traffic from Gippsland while we complete safety upgrades on this priority route, works on the Princes Highway between Stratford and Sale have been postponed. At this stage we will only be working outside of peak travel times on the outbound lanes of the Highway, between Bunyip and Officer.

We are monitoring traffic conditions during works and in the event of an emergency, our mobile works site will be removed from the road immediately to ensure that all lanes of traffic remain open. To keep up-to-date with the latest road closure and traffic impact information, visit VicTraffic.


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.

In the five-year period between 2012 and 2017, there were 25 crashes recorded along this road, resulting in 6 people suffering serious injuries .   

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. 


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.

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.
