Tonkin Highway is part of Perth’s Principal Road Freight Network that serves key activity centres such as Perth Airport and the Kewdale Freight Terminal.

This project will upgrade a section of the Tonkin Highway from Collier Road to Dunreath Drive with associated works enabling METRONET’s Morley-Ellenbrook Line.

Works as part of this project include:

  • additional traffic lanes in each direction between Collier Road and Dunreath Drive
  • new bridges over the Swan River, Guildford Road, Railway Parade and Dunstone Road
  • upgrades to the Guildford Road and Great Eastern Highway interchanges
  • a Principal Shared Path (PSP) with bridges, underpasses and local connections for cyclists and pedestrians
  • noise walls, lighting and amenity improvements


  • Alleviate pressure on the existing transport network.
  • Improved road safety and reduce congestion for all road users.
  • Improved freight efficiency, connectivity and travel time.
  • Address a major bottleneck on Tonkin Highway through Bayswater which carries more than 120,000 vehicles daily
