Roe Highway Upgrade (Tonkin Highway to Orrong Road)


Latest news

The Roe Highway Upgrade between Tonkin Highway and Orrong Road has been completed within budget.

By increasing the number of lanes in each direction and improving merge points, traffic flow has improved, leading to safer journeys for commuters, local residents and the freight industry.  We thank road users to their patience and support during the construction period.


We have progressively developed Roe Highway over more than 15 years as part of Perth’s strategic freight network. This upgrade and widening works will ease congestion and encourage free-flowing traffic at a "pinch-point" close to Roe Highway and Tonkin Highway interchange.  More than 52,000 vehicles, including 6,000 heavy vehicles use this section of road daily.

The project reinforces the Government’s commitment to improving safety and reducing congestion for all road users in Perth’s southern suburbs.


Project timing  

The upgrade was completed in April 2017 with all new lanes open to traffic.



The project upgrades a two kilometre section of Roe Highway from Tonkin Highway to Orrong Road. Works include:

  • Widening the existing road with additional lanes in each direction
  • Installing a new bridge over the freight railway near Sheffield Road
  • Providing a new off-road shared path for cyclists and pedestrians



The $41 million project is being delivered by McConnell Dowell Constructors (Aust) Pty Ltd.


Project benefits will include:

  • Improved traffic times
  • Improved road safety
  • Better cycling and pedestrian options
  • Landscaping and revegetation works
