Whiteman Yanchep Highway - Gnangara Road to Neaves Road

​Alignment Definition Study




We are undertaking an Alignment Definition Study to identify and protect the road reservation for a future Whiteman Yanchep Highway, between Gnangara Road and Neaves Road.

The Whiteman Yanchep Highway is a proposed new north-south route in the North-West Corridor of Perth. It is initially planned to connect Tonkin Highway and Neaves Road and this section is forecast to be required by 2031. It will eventually provide a strategic link to Mitchell Freeway in the Yanchep area when Perth’s population reaches 3.5 million. Planning for the section between Tonkin Highway and Gnangara Road was undertaken as part of the NorthLink WA project.

This new highway will improve connectivity between planned urban development and employment centres and facilitate the movement of regional freight and commuter traffic. It may also facilitate future public transport development as it will include space for heavy rail within the median.

The Alignment Definition Study has been conducted in close consultation with key stakeholders, including local government. It has included transport modelling and traffic analysis, preparation of a planning design concern, and environmental impact assessment and a noise impact assessment.

It is important to note this is a planning study only and no funding is currently available for construction.


The route

The proposed Whiteman Yanchep Highway, between Gnangara Road and Neaves Road, runs to the east of the area covered by the East Wanneroo Structure Plan and is shown on the map


Next steps

Community consultation is the final stage of the study. We are seeking all feedback by the end of January to ensure it is considered as part of our final submission to the Western Australian Planning Commission, which will be seeking an amendment to the Metropolitan Region Scheme. This will ensure the land required for the proposed future highway route is protected and provide certainty for landowners.

The MRS amendment will be advertised and will also include a formal public comment period.
