This project sees the construction of a new bridge over the Kwinana Freeway, including the installation of free-flowing lanes on Armadale Road through to Solomon Road.

A grade-separated roundabout is also being installed at the intersection of Armadale Road and Solomon Road, and Armadale Road and Tapper Road, allowing traffic to crossover at differing heights.

Commuters can also look forward to an upgrade to the Cockburn Central Station eastern car park with 1100 bays, including ACROD and future electronic vehicle parking, motorcycle bays, bike lockers, and a kiss n’ ride drop off zone.

The project has programmed the car park works in stages to reduce inconvenience to commuters and motorists as much as possible and to ensure some car parking remains available to station patrons during construction.


  • Ease traffic congestion at Cockburn Central Station and Cockburn Gateway Shopping Centre
  • Reduce congestion and provide additional traffic capacity
  • Improve access to Kwinana Freeway and Cockburn Central Station
