South Gippsland Highway, Lynbrook Boulevard to Manks Road

The Victorian Government is improving safety on South Gippsland Highway, between Lynbrook Boulevard in Lynbrook and Manks Road in Clyde, in partnership with the Transport Accident Commission (TAC). 

Project update - March 2022

We’re improving safety along South Gippsland Highway, between Lynbrook Boulevard and Manks Road, as part of a $9.8 million investment to reduce road trauma and save lives.

To prevent head-on and run-off-road crashes and reduce road trauma, we’re installing additional flexible safety barriers along the left-hand side and centre median of this stretch of road.

Works are progressing and are expected to be completed in mid to late 2022, weather permitting.

In the coming months, crews will also begin the installation of an Electronic Speed Limit Sign (ESLS) on South Gippsland Highway near Devon Road.

These works are being delivered as part of the Australian and Victorian governments’ multi-million-dollar Road Safety Program and aims to provide greater protection for vulnerable road users such as cyclists and pedestrians. For more information on ESLS, visit the Road Safety Program web page.

What this means for you

When works are underway, crews will be on site Monday to Friday from 7am to 6pm, with possible works on Saturdays. 

Road users will experience the following disruptions:

  • a reduced speed of 40km/h through the work site during construction hours, to protect workers and road users 
  • a reduced speed of 60km/h outside of construction hours to protect road users.

Crews will aim to maintain two-way traffic where possible, and access to properties on the South Gippsland Highway will be kept open.

If you’re travelling through the area, keep an eye out for changed traffic conditions, plan ahead and allow for extra travel time.

Environmental Sustainability

We will balance our commitment to environmental sustainability with the critical need to improve safety on this road to reduce road trauma and save lives. 

We are continually working to reduce environmental impacts, however we may need to remove a limited number of trees along the project site to allow for the installation of the life-saving flexible safety barriers. 

We are working with the City of Casey to investigate opportunities to plant additional flora along the project site, and with local environmental groups to repurpose any tree trimmings to assist wildlife rescue organisations. 

Why we're installing flexible safety barriers

Flexible safety barriers are already in place along some sections of the South Gippsland Highway. We’re installing additional flexible safety barriers to provide a safer journey and reduce the risk of head-on and run-off-road crashes.

Mistakes happen, which as humans we can’t always avoid. What we can do is build more forgiving road infrastructure so that when a mistake does happen on the road, it doesn’t cost a life. 

Road safety infrastructure such as flexible safety barriers, wide centreline treatments and rumble strips help prevent the most common crash types – head-on and run-off-road collisions – which in 2015 were responsible for 40 per cent of Victoria’s road deaths and serious injuries.

Infrastructure plays a vital role in preventing serious crashes. It also helps to reduce the severity of crashes when they’re unavoidable.

The section of South Gippsland Highway between Lynbrook Boulevard and Manks Road is a high-volume, high-speed road in Victoria’s Metropolitan south east region and connects the growing suburban regions of Cranbourne and Clyde to Melbourne.

Between 2012 and 2016, 35 crashes occurred on South Gippsland Highway between Lynbrook Boulevard and Manks Road; 25 people suffered serious injuries and tragically one person lost their life. 

Flexible safety barriers will not be installed on a section of the South Gippsland Highway between Clarendon Street and Cameron Street in Cranbourne due to the 60km/h speed limit and the Avenue of Honour which commemorates sacrifices made by those who served in World War I.

These safety upgrades build on the investment made to improve safety on South Gippsland Highway between Cranbourne East and Lang Lang as part of the Victorian Government’s $1.4 billion partnership with TAC, into road safety infrastructure to reduce road trauma and save lives.
