Kwinana Freeway Northbound Widening

  • Widening the freeway from Russell Road to Roe Highway
  • Construction commenced in 2018 and is expected to be completed in late-2019
  • Reduce travel times and ease congestion


This project forms part of our overall plan to transform Mitchell and Kwinana freeways to support population growth and economic development. It involves widening Kwinana Freeway, providing an additional lane between Russell Road and Berrigan Drive and two additional lanes from Berrigan Drive to Farrington Road.

Other works include:

  • Construction of noise walls where required along the western side of Kwinana Freeway
  • Upgrade and realignment of the existing Principal Shared Path (PSP)
  • Modifications to drainage, kerbing, surfacing, lighting, road safety barriers, service relocations, signage and line marking

Related works in the area:

  • Construction of Collector Distributor (CD) roads associated with the Armadale Road to North Lake Road Bridge project. CD roads are lower speed roads parallel to the freeway to provide merging opportunities.
  • Construction of a fourth lane along Kwinana Freeway from the CD road on-ramp to the freight rail line.

Project Update

PSP detour update

The fifth phase of cyclist and pedestrian detours will begin in the coming days with changes at the northern and southern ends of the works. Please see our latest update for more information.

Upgrade and closure of PSP access points

The existing Principal Shared Path between Russell Road and Farrington Road is being realigned to provide space for the additional northbound freeway lanes. Twelve access points are being upgraded as part of works. Eight existing access points cannot be upgraded to meet the new standard and will permanently close.
