Thompsons Road Upgrade, Cranbourne

The Victorian Government has committed $207 million to 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 Thompsons Road upgrade includes $143 million for the duplication of Thompsons Road between Dandenong-Frankston Road and Berwick-Cranbourne Road (Clyde Road), as well as $64 million for the removal of the Cranbourne Line level crossing.

Thompsons Road level crossing – gone for good

Works to remove the dangerous and congested Thompsons Road level crossing are almost complete. The removal is one part of major works underway to upgrade Thompsons Road, and is being delivered by VicRoads on behalf of the Level Crossing Removal Authority.

What we are doing

On Sunday 24 June 2018 we’ll open the newly constructed northern bridge.

From this day, traffic on Thompsons Road will divert onto the new bridge and you will no longer have to wait at the dangerous and congested level crossing.

When both bridges are complete, there will be six lanes of traffic over the train line, to get you where you’re going sooner and safer.

What to expect

Thompsons Road will be temporarily closed before the new bridge opens

Before we open the new bridge, we need to temporarily close Thompsons Road to realign the Evans Road roundabout to match the new traffic lanes on Thompsons Road.

We’ll close Thompsons Road between Marriott and Merinda Park Boulevards from Friday 22 June at 9pm to the evening of Sunday 24 June 2018.

While we do this, we’ll also realign road safety barriers, and add new signs and linemarking.

During the road closure, detours will be in place [Please refer to below map]

  1. for traffic on Thompsons Road, a detour will be available via Western Port Highway, Hall Road, Cranbourne-Frankston Road, South Gippsland Highway and Central Parkway
  2. for local traffic on Evans Road North of Thompsons Road, a detour will be available via Marriott Boulevard and Merinda Park Boulevard
  3. for local traffic on Evans Road South of Thompsons Road, a detour will be available via South Gippsland Highway and Central Parkway.

We encourage you to plan your trip in advance and allow for extra travel time.

To keep you and our work crews safe, please follow traffic controllers and set speed limits.

Traffic changes

From Sunday 24 June 2018, we’ll open the new northern bridge and divert traffic onto the new lanes.

When your journey diverts onto the new bridge, there will be one lane of traffic each way on the Thompsons Road bridge. However, you’ll now no longer stop at the level crossing.

With the northern bridge open, we’ll continue to finish work on the shared walking and cycling paths. We’ll also start to build the southern bridge and new traffic lanes on the south side of Thompsons Road.

While traffic is diverted, keep an eye out for signage to guide you along the new route [Please refer to the below map]

Bus routes may temporarily change – visit for details.

Project update - June 2018

Western section (Dandenong-Frankston Road to Western Port Highway)  

We’ve been busy building extra lanes along Thompsons Road. Two extra lanes will be built in each direction, between Dandenong-Frankston Road and McCormicks Road, as well as one extra lane in each direction between McCormicks Road and the Western Port Highway intersection. These new lanes will help improve traffic flow and travel times on this busy road.

Service relocations

Over the past month, we’ve been relocating services in the area, such as gas and oil pipeline services, to allow us to build the new lanes.
In March, we also worked at night to remove and relocate power poles at the McCormicks and Thompsons Road intersection to make way for the new traffic lights. 

Safety barriers

To help protect you on your journey, we’ve started installing wire rope safety barriers along the north of Thompsons Road. These new barriers will reduce the risk of run-off road crashes, improving safety on our roads. 

Bridge works

With foundation works completed in April, and the beams now in place, the low-level bridge over the Eastern Contour Drain is progressing well. 

Coming up

We’ll pour the concrete deck for the eastern contour drain bridge soon, which will form part of the new eastbound lanes. The new lanes will help ease congestion, getting you where you need to be sooner. We’ll continue laying new road surface between Dandenong-Frankston Road and McCormicks Road, and between Taylor’s Road and just past the Eastern Contour Drain.

Central section (Western Port Highway to South Gippsland Highway)

Service road

We’re almost finished upgrading the service road, located between Lonsdale Crescent and east of Gray Street. This upgrade included laying new road surface, adding drainage and putting up new signs.  

Lonsdale Crescent

At the end of April, we re-opened access to Lonsdale Crescent. Thank you for your patience while we upgraded this road. 

For the time being, access to the service road from Lonsdale Crescent will remain closed as we continue works. 

Walking and cycling path 

We’ve nearly finished building the shared walking and cycling path on the north side of Thompsons Road, between Marriott Boulevard and Evans Road. 

Concrete safety barriers 

You may have noticed some new safety barriers, which we installed in April. These barriers help to keep you and our workers safe, by separating traffic away from our work site. 

Coming up

Over the next few months, we’ll be:
  • laying new road surface for the eastbound lanes between Marriott Boulevard and Merinda Park Boulevard. We’ll continue doing this on the northern bridge, which will connect with the existing Thompsons Road near South Gippsland Highway 
  • building new kerbs 
  • adding new directional and speed limit signs 
  •  installing safety barriers. 

Northern bridge and eastbound lanes opening soon 

  • Soon, you’ll be able to use the new eastbound lanes between Marriott Boulevard and South Gippsland Highway. This major milestone includes opening the northern bridge, allowing us to remove the level crossing. 
  • Look out for more information about these changes on our website in the coming weeks.
  • Possible power disruptions 
  • You may experience some disruptions to power as we continue service relocations. AusNet will notify affected properties.

Eastern section (Narre-Warren Cranbourne Road to Berwick-Cranbourne Road) 

Westbound lane 

We’re making good progress on building the westbound lanes between Narre-Warren Cranbourne Road and Berwick-Cranbourne Road. So far, we’ve:
  • started building the kerbs between Berwick-Cranbourne Road and William Thwaites Boulevard
  • continued with drainage works, including installing drains for Ti Tree Creek 
  • continued to build new road layers.

Site office

We recently relocated the site office in the eastern section. It’s now located at 1660 Thompsons Road.

Coming up

Over the next few months, we’ll:

  • continue relocating services, including Telstra and power services and existing sewer and recycled water drainage
  • lay new road surface and install guardrails along the westbound lane.

We’re working towards moving traffic onto the new westbound lanes by late 2018.

Two extra intersection upgrades coming soon

In April, the Victorian Government announced further upgrades to two key intersections on Thompsons Road. The roundabouts at the intersections of Thompsons and Dandenong-Frankston Road and Thompsons and Narre Warren-Cranbourne Road will be replaced with traffic lights. 

These intersection upgrades form part of the Suburban Roads Upgrade, and will complement work already underway on Thompsons Road. We’ll keep you updated on the project once more information is available. 

School gets special delivery

Earlier this year the local secondary school, John Paul College, received an extra special delivery donated by the Thompsons Road Upgrade. 

Five large pinewood logs were felled from the eastern section to make way for the new road. We delivered the logs to the school for re-use in a variety of their school projects. 

The logs are now being put to great use at John Paul College, by both their VCAL program and technology department. 

Year 10 and 11 students will learn how to create bench seats and other furniture pieces, as well as common household items such as clocks, chopping boards and even salad servers. 

We’re thrilled to have been able to provide this unique opportunity to the school, and we look forward to checking in on the students’ progress over the coming months.

During construction there’ll be ongoing changes to traffic management, including reduced speed limits and lane closures. We’ll work to keep disruptions to a minimum and keep you updated on all the changes with road signs and through our website. We’ll also keep you updated about upcoming works through letterbox drops, door-knocks and email updates.

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

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 area.

About the project

The Thompsons Road Upgrade will greatly improve connectivity for those who live and work in the region, helping with 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 we can. 

For the trees that will be removed, we’re exploring a range of upcycle options. 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 collected seeds from the local River Red Gum trees, which we’ll pass onto local councils for replanting in the area.

You can learn more about our seed collection (External link) and what we’re using the seeds for [PDF 1.11 Mb] and how we're protecting the local environment and wildlife

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 8-metre-high wall. Stretched out from the back of numerous concrete panels, the straps will help support 140,000 tonnes of soil. 



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 each 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.

We expect to complete the level crossing removal by mid 2018.

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 make journeys easier along Thompsons Road. 

We’re also replacing the roundabout at Western Port Highway with traffic lights to help reduce your travel time during peak periods. We’re also 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.

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

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