Tonkin Gap Project Upgrades

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.

Upgrades included 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 included:

• 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 bike riders and pedestrians
• noise walls, lighting and amenity improvements

Additionally, a new Principal Shared Path (PSP) has been constructed on the western side of Tonkin Highway, providing a continuous connection path between Wattle Grove and Morley.
