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

Benefits

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

Shared path detour

From Thursday, 29 April we will be required to close sections of the PSP near Broun Avenue to start vegetation clearing and construction of the bridge footings. You may see an increase in the number of cyclists and pedestrians using local roads and footpaths in the area.

Please view the detour map for more information.
