Thompsons Road Upgrade, Cranbourne

The Victorian Government is funding the $175 million Thompsons Road Upgrade to improve safety and capacity for this vital east-west corridor in Melbourne's south-east growth region.

Project update - September 2017

Merinda Park Boulevard was opened to traffic in July 2017.

The newly-constructed road has been built with traffic lights and will provide safer access to and from Merinda Park Station.

The old entrance to the carpark at Merinda Park Station is now closed.

Construction crews are now working to build the new road bridges that will remove the dangerous and congested level crossing on Thompsons Road forever.

To do this one of the first activities completed is the installation of piles in the ground to support the bridges. This will be followed by construction of a new retaining wall that we will build up to allow the bridge to be built.

You will notice large earth moving equipment and trucks moving around the site. For your own safety we urge you to continue to use the pedestrian detour in place to access the Merinda Park station, and cross Thompsons Road at the signalised pedestrian crossing near Lesdon Avenue.

We are also still working to:

  • Construct three new eastbound lanes of Thompsons Road, from Marriott Boulevard to Lonsdale Crescent.
  • Protect or relocate utility services, making way for the new pavement on the service lane between Lonsdale Crescent and Lesdon Avenue.

To see what the road will look like once completed view our video below.


Throughout the duration of the project, we’ll work hard to keep disruptions to a minimum and will notify affected residents well in advance about upcoming works through letterbox drops and door-knocks.

We appreciate your patience and understanding as we work to deliver this essential 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 kms of Thompsons Road to improve the connectivity 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 will be completed in two stages.

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. Stage one of the Thompsons Road Upgrade includes an upgrade from Marriott Boulevard to the South Gippsland Highway to three lanes in each direction and removal of the level crossing.

A road over the rail is the most appropriate solution for removing the level crossing due to the groundwater challenges in this area. The overpass will consist of two separate bridges providing three traffic lanes and a shared use path. This allows the overpass to be constructed in two stages, minimising the disruption to road and rail users during the works.

This map outlines where the Thompsons Road stage one level crossing removal is located and shows new traffic signals and shared path routes.

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

Thank you for your patience.

This stage of the project is targeted for completion  in late 2018.

We'll be adding an additional lane in each direction from: 

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

We’re also replacing the roundabout at Western Port Highway with traffic signals (which will reduce your travel time during peak periods) as well providing traffic signals at McCormicks Road.

We'll be constructing up to 10 kilometres of shared use paths to give the community a safe, sustainable and convenient way to connect with community facilities and public transport hubs.

While tree removal will be required for the works, 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.

These works are expected to begin in late 2017 and we’ll be working closely with our contract partners to minimise disruption to road users.

We're expecting that both stages of the Thompsons Road Upgrade will be completed by mid 2019.
