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

While we put the finishing touches on the duplication of Thompsons Road, works have now started to upgrade the roundabout at Frankston-Dandenong Road and Thompsons Road to traffic lights.

From Monday 7 October until further notice, we’ll reduce the northbound and eastbound lanes on the approach and through the roundabout from three to two lanes. See the below diagram for more details.

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

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.

Construction will be ongoing until mid next year with major disruptions expected as we reduce lanes at the roundabout to make way for crews and machines to work behind the safety barriers. That means traffic conditions in this area will be worse before it gets better.

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

We’ll endeavour to complete the works as soon as possible and thank you for your understanding and patience during this important upgrade.

Final work on the new lanes on Thompsons Road

From October to November 2019, we’ll be laying the final asphalt across sections of the newly duplicated Thompsons Road. We’ll reduce Thompsons Road to one lane in each direction and work at night while there are fewer cars on the road.  In some areas we may need to set up overnight detours to complete these works.

With concreting, permanent street lighting, and landscaping wrapping up, all work on the duplicated Thompsons Road will be fully completed by the end of the year. At the same time, we’ll be gearing up to open the shared walking and cycling path across the project.

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.
