Principal Shared Path Expansion Program

Expansion of the principal shared path network helps Western Australians to choose walking, wheeling, or riding as part of their everyday journey and experiences.

Show all

What are principal shared paths?

A principal shared path (PSP) is a high-quality shared path for walking and riding, built to Main Roads WA PSP standard. This generally means the path will be 4-m-wide, have adequate lighting and be grade separated at intersections.

PSPs form the backbone of the Western Australian bike network, and often follow freeway and rail corridors. PSPs provide for safer off-road travel, with minimal interruption from other traffic, and more direct riding and walking trips.

To create more enjoyable walking and riding experiences, where possible, efforts are made to enhance the amenity of PSPs. For example, artwork may be included in walls and underpasses and the incorporation of natural landscaping is prioritised as part of the green transport route initiative.

What is the PSP expansion program?

Expanding the PSP network is a key action of the Western Australian Bicycle Network Plan 2014-2031 (WABN Plan) and is being delivered as part of state-wide major transport infrastructure projects such as METRONET.

The WABN Plan includes a series of key actions, designed to provide a safe and sustainable bicycle network between major activity and attraction areas.

Initial works were concentrated within a 15 km radius of the Perth central area with a particular emphasis along the freeway and railway corridors, due to high commuter demand.

Since 2023 the focus has moved to areas beyond the 15 km radius of the Perth central area to provide greater connectivity for strategic activity centres.

Completed and current projects

Recently completed PSP projects, along with projects in construction and planning stages are itemised in the downloadable map below.

Information about specific PSP projects is published in the WABN Annual Progress Reports available on the WABN Plan webpage. Key projects are also listed in the Building for Tomorrow website (search 'shared path').

Program evaluation

PSP projects are being evaluated in line with the Department of Transport’s PSP Key Investment Projects Evaluation Plan, which has adopted a summative evaluation framework that considers impacts, cost effectiveness and efficiency of project delivery. A full report is due to be published soon. An interim summary highlighting the primary route evaluation for sections along the Fremantle Railway PSP and Mitchell Freeway PSP can be found below.
