Project Description

The Project involves construction of a two-lane second carriageway for 6.96 kilometres of Armadale Road between Anstey Road and Tapper Road.

The Project also includes upgrade works at three intersections; grade separation on Nicholson Road; construction of a principal shared path; street lighting and drainage; provision of two-metre sealed shoulders; as well as significant service relocations and associated works.


As one of the main east-west links in the Perth metropolitan transport network, Armadale Road is used by 27,500 vehicles per day.  It has a high crash rate attributed to its role as a link between Perth's two southern public transport corridors and as an access route to other major arterial roads — including Kwinana Freeway, and the Tonkin, South Western and Albany Highways.

The project is anticipated to significantly improve safety and ease traffic congestion on Armadale Road.


The Australian Government has committed $116 million towards the $145 million project.


Construction commenced in March 2018 and is anticipated to be complete in late 2019.
