Please be advised that following safety concerns raised by the City of Kalamunda, Main Roads Heavy Vehicle Services (HVS) reviewed Restricted Access Vehicle (RAV) access at the intersection of Harrison Road and Berkshire Road, Forrestfield.

Due to non-compliant swept paths being identified, all turning movements will be restricted for the following RAV Networks:

• Tandem Drive Networks 2 to 7
• AMMS Tandem Drive Networks 2.1 to 7.1
• PBS Tandem Drive Network PBS2B.1
• Concessional Livestock Networks 2 to 5
• Oversize B-Double Network
• Oversize Divisible Products Networks 2 to 6

Alternative access for the above RAV Networks is available via Walters Way. Refer to the RAV Mapping Tool for approved networks.

This change will take effect from Wednesday 11 November 2026 and will be reflected in the relevant Road Tables and RAV Mapping Tool on our website from that date.

For further information, please contact the Heavy Vehicle Services Helpdesk on 138 486 and ask to speak to a Route Assessment Team member or email hvsrouteassessments@mainroads.wa.gov.au.
