Project update - March 2017

Works are ramping up on Thompsons Road.  From March you’ll notice an increase in the presence of workers, deliveries of plant and equipment, light and heavy vehicles accessing the site and earthwork activities as we continue to: 
  • Build Merinda Park Boulevard.  A new road that will provide safer access to and from Merinda Park Station
  • Prepare for the construction of the two bridges removing the level crossing.  This will require making changes to how pedestrians will be able to get to and from Merinda Park Station.  For your safety we ask that you follow the detour signs and pay particular attention to the ongoing works around you
  • Excavate and commence construction behind the barriers between Marriott Boulevard and Lonsdale Crescent for the new eastbound lanes of Thompsons Road
  • Protect and relocate utility services making way for the new pavement on the service lane between Lonsdale Crescent and Lesdon Avenue

We appreciate your patience and understanding as we work to deliver this essential upgrade. You can read more about the upgrade in our most recent and previous project updates below.

Managing dust and dirt

To manage the amount of dust and dirt that the construction work will generate, we're doing a number of things to reduce the impact on the community.

  • planning earthworks for days with the best wind conditions
  • watering earthworks, especially on hot and windy days
  • covering truck loads and stockpiles
  • reducing the speed of construction vehicles
  • seeding topsoil stockpiles

We're also using recycled water where possible.

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 Thompsons Road to 10.7km to improve the connectivity for those who live and work in the region.

About the project

The 10.7km 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 (External link). 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 will be completed by late 2018.

We'll be adding an additional lane in each direction from Dandenong-Frankston Road to Marriott Boulevard and from Narre Warren-Cranbourne Road to Berwick-Cranbourne Road. 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 and at Evans 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 the majority of the River Red Gums along the western section of Thompsons Road untouched. 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.
