The level crossing near Merinda Park Station has gone and we’ve added extra lanes and traffic lights on Thompsons Road to improve safety and travel times.


Frankston-Dandenong Road roundabout upgrade works

Works have now started at Frankston-Dandenong Road and Thompsons Road to upgrade the roundabout to traffic lights.

From November 2019 until further notice, we’ll reduce the roundabout from three to two lanes in all directions.

Long delays are expected at this major intersection. If possible, please seek alternative routes, especially during peak periods.

Speed limit on Thompsons Road

While we celebrated the end of major construction on Thompsons Road last June, we’ve continued works to landscape the new road, lay the final surface and connect permanent street lighting.

We’ve reinstated the speed limit on sections of Thompsons Road where these final works are complete. These areas are:

  • 90 km/h between Frankston-Dandenong Road and Western Port Highway
  • 80 km/h between Narre Warren-Cranbourne Road and Berwick-Cranbourne Road.

Unfortunately, weather late last year affected progress on final works between Western Port Highway and South Gippsland Highway, as laying the final surface requires certain temperatures. We’re working hard to lay the final surface and connect permanent lighting through this section.  Until then, speed limits will remain at 60km/h for the safety of all road users in this road section.

Last piece of the puzzle  

More than 58,000 vehicles travel through the Frankston-Dandenong Road roundabout at Thompsons Road every day, making it an extremely busy freight and transport link in the east-west corridor of Melbourne’s south-east.

Originally funded to be delivered as part of the Suburban Roads Upgrade package, construction of this roundabout has been brought forward to allow for delivery of this upgrade up to three years earlier than planned.

That means heavy congestion at this roundabout will soon be a thing of the past. We’ve now started work to transform it to a fully-signalised intersection that will improve traffic flow and ease congestion, linking it to the recently completed new lanes on Thompsons Road.

By the time the project is finished later in 2020, there will be three lanes travelling through the intersection and two right turn lanes at all approaches, providing a more reliable and smoother journey for vehicles travelling through the intersection.

We’re also building dedicated left turn slip lanes on each approach to the intersection, so vehicles can turn left without affecting the flow of the through traffic.

All of this will mean that more vehicles can get through the intersection on each light sequence.

The new traffic lights will use detectors to sense traffic flow at different times of day. Green light time can then be allocated where the need is greatest.

We'll work at the intersection until late next year with major disruptions expected.

Please look out for signage to guide you through and around our works zone. We encourage you to plan your trip ahead and, if possible, find alternate routes to avoid this area.

We’re working hard to finish works as soon as possible and thank you for your understanding and patience during this important upgrade.

Final works on the new Thompsons Road

We’re currently laying the final surface and connecting permanent street lighting on Thompsons Road between Western Port Highway and South Gippsland Highway.

Lane closures in February

We’ll work during the day and sometimes at night through February 2020 on Thompsons Road, between South Gippsland Highway and Marriot Boulevard.

We'll reduce sections of Thompsons Road to one lane in each direction at times until mid February. We’ll mostly work at night between 7pm to 6am, with some day work possible depending on weather conditions.

Walking and cycling

While we've completed most of the 10km of new shared walking and cycling paths, a few small sections still need finishing touches. We've got a little more work to do on the path over the Thompsons Road rail bridge and the path between Frankston-Dandenong Road and McCormicks Road.

We apologise for the delay and will let you know as soon as they are ready for public use.

As part of this upgrade, we’ve:

  • duplicated Thompsons Road between Frankston-Dandenong Road and Berwick-Cranbourne Road, with at least two traffic lanes in each direction
  • replaced the roundabouts at Western Port Highway, McCormicks Road, and Evans Road with traffic lights
  • built new road and new traffic lights at Merinda Park Boulevard.

10.7kms of new lanes

New walking and cycling paths

New bridges over train line and level crossing removed
