Thompsons Road Upgrade, Cranbourne

The Victorian Government is funding the Thompsons Road Upgrade so you can experience improved safety and travel times on this vital east-west corridor in Melbourne's south-east growth region. The upgrade includes $65.9 million to remove the dangerous level crossing and $175 million to duplicate Thompsons Road from Dandenong-Frankston Road to Berwick-Cranbourne Road (Clyde Road).

Project update - January 2018

Project progress – Level crossing removal

New bridge taking shape

We’re ramping up works for the bridge build on the north side of Thompsons Road, bringing us one step closer to removing the dangerous and congested level crossing for good. We’re delivering the level crossing removal on behalf of the Level Crossing Removal Authority. 

We’ve now completed laying the bridge foundations – a huge milestone for the project  – after drilling numerous holes of up to 25m deep to provide a stable base for the new bridge. We’ve also installed 170 concrete panels to create a retaining wall, which supports the bridge, on both sides of the railway. 

Full steam ahead for bridge beams

We’re about to start lifting and placing the bridge beams over the railway line. These beams are the main structure that will help create the new bridge.  

Each beam weighs between 45–50 tonnes and is 28m long. Due to their sheer size and weight, we’ll use 250 and 350 tonne cranes to lift them into place. Abutments and concrete columns, which you can now see on site, will support the beams at each end of the bridge.

Check out the construction video (External link)  and Thompsons Road Upgrade January 2018 (External link) to see our progress.

Upcoming works

We’ll complete the bridge beam works in 3 stages, which we’ve scheduled as follows:

  • first 7 beams lifted and placed over the railway line from 25–27 January 2018 between 9pm and 5am each night, with preparation works starting from 7pm
  • next 7 beams lifted and placed on the west side of the bridge during the day from 30 January – 2 February 2018 between 7am–6pm
  • last 7 beams secured to the east side of the bridge from 30 January – 2 February 2018 between 7am–6pm. 

Public transport changes 

So we can safely complete these works, buses will replace trains from 8pm each night until the last service from 25–27 January between Dandenong Station and Cranbourne Station. Visit the PTV website (External link) to find out more. 

Dates are subject to change and other works may also happen during this period. 

Traffic changes 

During the beam installation, you can expect the following changes:

  • speed limit on Thompsons Road lowered to 40 km/h 
  • only 1 lane open between Lonsdale Crescent and Merinda Park Boulevard during the night works
  • traffic controllers present to direct traffic flow
  • access to Merinda Park Boulevard and the Merinda Park Station car park from Thompson Road will be closed during night works. We suggest using the alternative route via Evans Road north to Merinda Park Boulevard
  • some noise from construction equipment and reverse beepers if you live nearby
  • some delays if you’re travelling through the area, so it’s a good idea to allow extra time when planning your journey. 

Pedestrian access to the train station won’t change. Our workers are mindful to keep noise to a minimum and respect the local community.

Project progress – Duplication of Thompsons Road

Major works for the duplication of Thompsons Road to improve safety and traffic flow are well underway. Check out our progress video (External link).

We’re building the duplication in 3 sections along Thompsons Road:

  • Western section: Frankston-Dandenong Road to Western Port Highway

We’ve started widening this section away from traffic first to help reduce impacts. Once this new road is complete, we’ll move traffic onto this road and then start works on the southern side of Thompsons Road.

In addition to widening the road, other works will include relocating utility services and adding drains, lights, safety barriers and a walking and cycling path.

Speed has been set to 60km/h as trucks come in and out of the work area, so please drive safely.

  • Central section: Western Port Highway to South Gippsland Highway

We’re continuing works on the Thompsons Road service road.

  • Eastern Section: Narre Warren Road to Berwick-Cranbourne Road

We’ve started digging and moving soil to widen this new part of the road. We’ve dug deep so we can start placing the layers needed to build the new road surface. We’ve set the speed limit to 60km/h in this area for your safety and the safety of our workers.


Throughout the project, we’ll work to keep disruptions to a minimum. We’ll keep you updated about upcoming works through letterbox drops and door-knocks.

A detour is in place to guide pedestrians around the busy work area for the bridge, which you can see on the map below.

We appreciate your patience and understanding as we work to deliver this much needed upgrade.

Project background

Thompsons Road is a vital east-west connection in Melbourne's south-east growth region, extending from the Mornington Peninsula Freeway in Patterson Lakes, to Berwick-Cranbourne Road in Clyde North. It’s an essential freight and transport route which carries around 26,000 vehicles each day.

With this number set to increase, the Victorian Government is duplicating 10.7 kilometres of Thompsons Road to help provide smoother journeys for those who live and work in the region.

About the project

The Thompsons Road Upgrade will greatly improve connectivity for those who live and work in the region, giving people better access to jobs, services and transport hubs in the south-east. The project includes the level crossing removal at Merinda Park Station and the duplication of Thompsons Road between Dandenong-Frankston Road and Berwick-Cranbourne Road.

Trees and vegetation

In order to build extra lanes on Thompsons Road, some trees and shrubs unfortunately have to go.

To help minimise the amount of trees that have to be removed, we’ve engaged independent ecologists and arborists, who have helped us refine the design to avoid removals where possible. 

For the trees that will be removed, we’ll explore a range of reuse opportunities. We’ll also provide logs to local councils for use in nature reserves.

To maintain Victoria’s biodiversity we’ve purchased native vegetation offsets for the Grey Billy Button, a native Australian wildflower. 

We’ve also completed seed collection from the River Red Gum trees, which will be offered to local councils and considered for replanting in the area where appropriate.

Supporting Australian manufacturing

Late last year we started building the reinforced retaining wall, designed to hold back earth and support the bridge over the railway line. Almost 16,000 100% Australian-made steel straps were ordered for the soon-to-be 8-metre-high wall. Stretched across the back of numerous concrete panels, the straps will help support 140,000 tonnes of soil. 

In November 2015, $65.9 million was added to the project to remove the Thompsons Road level crossing on behalf of the Level Crossing Removal Authority. These works include building 2 bridges over the rail line with three lanes.

A road over the rail is the most appropriate solution for removing the level crossing due to the groundwater challenges in this area. This overpass includes 2 separate bridges with 3 traffic lanes and a shared walking and cycling path. Building 2 bridges allows us to create the overpass in 2 stages, minimising disruption to drivers and commuters during the works.

During construction there’ll be ongoing changes to traffic management, including reduced speed limits and temporary lane closures. We’ll work to minimise disruption and we'll keep you updated on all the changes with road signs and through our website.

We expect to complete the level crossing removal by late 2018. Thank you for your patience.

We're duplicating Thompsons Road from Dandenong-Frankston Road to Berwick-Cranbourne Road, making it one continuous two-lane road. 

We’re adding an additional lane in each direction from:  

The new lanes will improve traffic flow and create more reliable journeys along Thompsons Road. 

We’re also replacing the roundabout at Western Port Highway with traffic lights, which will reduce your travel time during peak periods, and adding traffic lights at McCormicks Road.

We'll be building up to 10kms of shared walking and cycling paths to give you a safe, sustainable and convenient way to connect with community facilities and public transport hubs.

While tree removal will be required for the upgrade, we’re working to keep as many of the River Red Gums along the western section of Thompsons Road as possible. By working with the relevant authorities, environmental specialists and community groups, we can balance the needs of the environment and the community.

We're expecting to complete the entire Thompsons Road Upgrade by mid 2019.
