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 include construction of Collector Distributor (CD) roads associated with works in Armadale - Open the Armadale Road to North Lake Road Bridge project page. CD roads are lower speed roads parallel to the freeway to provide merging opportunities. In addition to construction of a fourth lane along Kwinana Freeway from the CD road on-ramp to the freight rail line.
Construction is underway across the entire eight km length of the project site.
Current activities include:
- Deployment of traffic barriers to enable the widening of the freeway, and separate road users from construction activities.
- Upgrading 8km of the Principal Shared Path (PSP) including realignments to eliminate tight bends, widenings and resurfacing.
- Construction of noise walls on the northbound side of the Kwinana Freeway, between Russell Road and Roe Highway.
- Construction of a retaining wall between Berrigan Drive and Bolderwood Reserve, which will retain the PSP for cyclists and pedestrians. The wall is being constructed using ECO blocks; environmentally friendly bricks comprising recycled construction waste.
- Utilising crushed recycled concrete and demolition waste as road base, in line with the guidelines jointly developed with the Department of Water and Environmental Regulation.

Open temporary access changes and closures PDF for more information on the
changes and closures implemented on Wednesday 14 August 2019 to facilitate the realignment of the Beeliar Drive on ramp to Kwinana Freeway. These changes will be in place for approximately two months.
Traffic management is being used to allow the freeway to stay open for the duration of the construction works. Changes include:
- Reduced lane widths
- Reduced speed to 80 km/h
- Variable speed signs for further night time speed reductions and lane closures: and
- The temporary closure of the emergency lane and replacement of the emergency stopping bays.

The sixth phase of cyclist and pedestrian detours will begin in early September with changes at the northern and southern ends of the works.Open the latest project update PDF 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 - Open Construction Update PDF.
