An aim of the Department of Transport is to make WA a place where riding is a safe, connected, convenient and widely accepted form of transport. Due to their versatility, Principal Shared Paths (PSP) are vital to encouraging the community to give riding a go. The paths can be used for long trips, but they are also suitable for less experienced riders and short trips, as well as for pedestrians.
The expansion of the PSP network was a key action of the Western Australian Bicycle Network Plan, delivered as part of State-wide major transport infrastructure projects.

Main Roads WA recently awarded Decmil the contract for the Mitchell Freeway PPS which included:

  • Construction of a new PSP within the City of Stirling between Civic Place and Erindale Rd (Length 2.46km)
  • The construction of the construction of a new PSP within the City of Stirling between Erindale Road and Reid Highway (Length 1.23km)
  • Upgrade of Karrinyup Road and Cedric Street intersection
  • Construction of a new Underpass under Karrinyup Road.

The project also saw an upgrade to the Erindale Road underpass, with a new artwork installation painted by students from Lake Gwelup Primary School.

With a large number of trees along the project, environmental management of this project was key, and the project’s design was carefully refined to minimise clearing. Clearing was carried out within the road reserve so as not to impact the City of Stirling parkland, and an extensive revegetation and landscaping plan, which included native trees and ground cover, was implemented.

Delivering solutions.

We are committed to outstanding project management and delivery regardless of the scale or the intricacy of the work.
