The $145 million Armadale Road dual carriageway upgrade in Perth’s southern suburbs has reached 95 per cent completion, with finishing works full steam ahead.

The project, which started in March 2018, has converted the previous four-way signalled Armadale Road and Beeliar Drive interchange – Perth’s fifth most congested intersection – into a four-lane bridge over Nicholson Road, with a roundabout underneath.

The project was fast-tracked in 2018 under the $2.3 billion “Boosting Jobs, Busting Congestion” infrastructure package announced by the Western Australian and Federal Government.

Over the next few weeks, works will be carried out to complete the asphalt and bridge works, which includes screen panel installation on top of the bridge at the Armadale Road, Verde Drive and Tapper Road intersection. The Principal Shared Path (PSP) will also be completed.

Finishing works, including kerbing are also in progress at Freshwater Drive and Armadale Road intersection to complete the permanent design.

The upgraded intersection at Armadale Road and Ghostgum Avenue opened earlier this month, with right turn movements between Armadale Road and Ghostgum Avenue reinstated following a long-term closure. This intersection has been reconfigured to provide additional turning capacity on Ghostgum Avenue, through lanes on Armadale Road.

The long-awaited section of Principal Shared Path (PSP) along Kwinana Freeway, between Beeliar Drive and Muriel Court, reopened in early September following a long-term closure.

As part of the State Government’s Roads to Reuse initiative, this project was tasked with using recycled construction and demolition products wherever possible. Working closely with nearby projects, suppliers, and environmental bodies, the project team has sourced around 29,000 tonnes of Crushed Recycled Concrete (CRC), which equates to almost one-third of the permanent road subbase on this project coming from recycled materials.

Nearly half of the CRC materials on this project has come from demolition of the iconic Subiaco Oval grandstands, with the remaining materials made up from nearby construction projects as well as onsite demolition materials.

The successful application of CRC on this project has prompted the Department of Treasury to use the Armadale Road to North Lake Road Bridge project as a case study to model the benefits of the Roads to Reuse initiative.
