Armadale Road Upgrade - Tapper Road to Anstey Road

The project will upgrade the 6.9 km section of Armadale Road from Tapper Road to Anstey Road. This is the last section of the single carriageway between Kwinana Freeway and Armadale.

The $145 million project, funded by the Commonwealth and State Government, will upgrade will the road from one suited to a semi-rural environment to an urban road able to service the increasing growth and development in the area.

Armadale Road is a strategic freight route connecting the South West and the South East corridor. It is one of the main east-west links within the Perth metropolitan transport network. The link passes through industrial areas, rural subdivisions, recently developed and planned residential subdivisions and connects Armadale sub-regional centre and Albany Highway, forming part of the route to the Fremantle Port.

Current traffic counts show that 27,000 vehicles use Armadale Road between Tapper Road and Warton Road, while 18,000 vehicles per day use Warton Road to Anstey Road.

The project will provide additional lane capacity to improve safety and operational efficiencies in the area, along with better access and traffic flow.

Construction updates

Construction of temporary shared path between Tapper Road and Ghostgum Avenue

A temporary path is being constructed between Tapper Road and Ghostgum Avenue in response to community feedback. Upon completion in late 2018, it will provide much-needed pedestrian and cyclist connectivity between Calleya Estate and the wider path network in Jandakot and Cockburn Central.

See our latest Construction Update for more information. 

No right turns at Liddelow Road and Armadale Road intersection

To improve safety, and in consultation with the City of Cockburn and local community, the intersection of Armadale Road and Liddelow Road will be reduced to left turn movements only as of 9pm on 21 May 2018.

No right turns will be permitted at the intersection during the construction of the Liddelow Road and Armadale Road roundabout, due for completion in late 2019.

See our Notice to Residents for westbound and northbound movement detours.

No cyclist access on Armadale Road between Ghostgum Avenue and Anstey Road

Road conditions have changed on Armadale Road, including steel barrier installation and reduced lane widths to 3.2 metres.

Cyclists are prohibited from travelling on Armadale Road between Ghostgum Avenue and Anstey Road. This will ensure the safety of cyclists during construction works.

This section of Armadale Road will remain closed to cyclists until late 2019, when new cycling and pedestrian facilities will open alongside Armadale Road.

See map for alternative routes.
