Thompsons Road safety improvements, Mornington Peninsula Freeway to Narre Warren Road

We’re improving safety along Thompson Road, between the Mornington Peninsula Freeway and Narre Warren Road, to reduce road trauma and save lives. 

Project update - March 2021

We’re installing flexible safety barriers along the left-hand side and centre-median of Thompson Road. 

Crews are currently onsite completing the installation of flexible safety barriers on Thompson Road between the Mornington Peninsula Freeway and Frankston-Dandenong Road.
Crews are working onsite from Sunday to Thursday night between 8pm and 5am to minimise disruption for commuters, until late March 2021.

Thompson Road, South Gippsland Highway to Narre Warren Road

From late March crews will begin installing flexible safety barriers on Thompson Road between South Gippsland Highway and Narre Warren Road, with works taking place Monday to Friday between 9.30am and 3.30pm. 

All safety upgrades on Thompson Road are expected to be completed in mid-2021, weather permitting.

What this means for you

While these safety upgrades are being delivered, drivers can expect the following: 

  • temporary worksite speeds of 40km/h during construction hours to ensure the safety of both road workers and drivers
  • one lane may be closed in either direction during the construction period to accommodate works.

Two way traffic in both directions will continue at all times and crews will work to minimise disruption where possible.

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

Keep an eye on this page for additional updates about the project.

We thank you for your patience while we complete these important safety improvements.

Night works

To minimise disruption to traffic flow during the day, we’ll carry out night works on Thompson Road, between the Mornington Peninsula Freeway and Frankston-Dandenong Road.

Works will be completed via a rolling worksite with crews working on 400 metre sections of road at a time. There will be safety management onsite to safely guide drivers through the area. Noise disruption is reduced where possible.

Nightworks are not scheduled for the works on Thompson Road, between South Gippsland Highway and Narre Warren Road.

What we're doing

Flexible safety barriers are already in place along some sections of the road. We’re installing additional flexible safety barriers on the left-hand side of the road to create a continuous safer journey and reduce the risk of run-off-road crashes. 

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

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% of Victoria’s road deaths and serious injuries. 

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.

Thompsons Road is a major road linking the Mornington Peninsula Freeway, Eastlink and the South Gippsland Highway. 

Between 2012 and 2016, there were 12 crashes recorded along this road, resulting in 13 people sustaining injuries, four of which suffered serious injuries.    

We’re improving safety along Thompsons Road, to build a future where no-one is seriously injured or killed on our roads.

As part of the jointly funded $245 million Road Safety Program, we’ll make further safety improvements to the local area by installing flexible safety barriers at high risk locations on Narre Warren-Cranbourne Road and Narre Warren - North Road between Princes Highway to Thompson Road and Princes Highway to Fox Road.

Working with Major Roads Projects Victoria

Nearby project: Thompsons Road Upgrade, Cranbourne to Carrum Downs

Major Road Projects Victoria (MRPV) are currently upgrading Thompsons Road between Cranbourne and Carrum Downs. 

We’re working with our partners at MRPV to ensure the timely delivery of both projects, and to mitigate impacts to the community, where construction may overlap.  

Have your say

We’ll continue to consult 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.
