​​​​​​​​​Armadale Road to North Lake Road Bridge

  • A new bridge over Kwinana Freeway connecting to North Lake Road with upgrades to Armadale Road
  • Construction began in late-2019 and is due for completion in late-2021
  • Ease congestion and improve access



Construction will ease congestion at Cockburn Central Station and the Cockburn Gateway Shopping Centre. The project will also provide a direct link between Armadale and North Lake roads, improve access to Kwinana Freeway and support residential and commercial expansion in Cockburn and Armadale.

The project also involves the construction of free flowing lanes on Armadale Road through Solomon Road and Tapper Road intersections with grade separated roundabouts introduced to retain full connectivity.

Other works will include:

  • North-facing on and off ramps at Kwinana Freeway.
  • Collector-distributor roads on both sides of the Kwinana Freeway from Berrigan Drive to Armadale Road
  • Modifications to the existing North Lake Road and Midgegooroo Avenue signalised intersection

Project Update

Closure of Solomon Road

Extensive pavement works are required on Solomon Road to enable construction of the new Armadale Road and Solomon Road interchange. Recent reductions in traffic volumes across the road network provide an opportunity put in place a 28-day closure, which will allow the works to be delivered in half the time of the original program. This will significantly reduce ongoing disruption to local businesses and motorists.

Solomon Road will be closed between Knock Place and Monash Gate from Monday 25 May to Monday 22 June. Please see the following Roadworks Update for detour information.

Building the Armadale Road interchanges

The Armadale Road to North Lake Road Bridge is a large and complex project in a tightly constrained residential and commercial area. Our latest Fact Sheet explains how we'll build the two new interchanges along Armadale Road while keeping traffic flowing.

Construction Update

The first phase of Armadale Road to North Lake Road Bridge project is well underway. Since late-2019, our focus has been on preparing the main alignment for major works. This activity has included the relocation of services infrastructure and the clearing of vegetation on both sides of Kwinana Freeway. Our site compound has also been installed to the east of Verde Drive to allow our crews to access the key work zones safely and efficiently. To find out more please see our April Construction Update.

Closure of Solomon Road access to business precinct

Vital works are underway to prepare for construction of a grade-separated roundabout at the intersection of Armadale Road and Solomon Road. To enable construction works to commence, the current access to the business precinct at 47 Armadale Road, via the former Puma petrol station site on Solomon Road, permanently closed in November 2019. For alternative access routes, please open the latest construction update document​.​
