Kwinana Freeway Northbound Widening - Russell Road to Roe Highway

​​​​​​Significant growth in traffic volumes over recent years has resulted in congestion and flow breakdown on Kwinana Freeway northbound, south of Roe Highway.

The State and Commonwealth Governments have committed $49 million to widen Kwinana Freeway northbound from Russell Road to Roe Highway, as part of a $2.3 billion package of road and rail infrastructure works, funded by the Australian ($1.6 billion) and State ($750 million) Governments, and announced by Premier Mark McGowan on 7 May 2017.

Upon completion, the project will reduce travel times and address congestion for road users in Perth’s southern suburbs.

This project forms part of our overall plan to transform Mitchell and Kwinana freeways to support population growth and economic development.

Shared path closures

The third phase of the path closures will commence from 10 December 2018 which includes a new detour at the southern end.

The detour will extend from Sweetwater Bend to Reeves Entrance, via Rutherford Entrance and Wentworth Parade.

From late-December, the northern end of the project will see a shortened detour with access to a new portion of the PSP via Hope Road, and a new underpass.

Commencement of Works

Construction work between Russell Road and Roe Highway commenced during the week of 29 October. Modified traffic arrangements are in place on the freeway and ramps. Speed limits is reduced to 80 km/h and further reductions to 60 km/h may be required at times. The freeway will remain open.

Scope of works

The project involves widening Kwinana Freeway to provide a third lane for the nine kilometres from Russell Road to Farrington Road. Other works include:

  • Construction of noise walls along the western side of Kwinana Freeway, where required according to noise modelling
  • 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

  • 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.
