Detour options

  • Cranford Avenue on-ramp closure

    Significant progress has been made on the new Cranford Avenue underpass, however ongoing inclement weather and the discovery of underground rock has delayed some construction activities.

    This means the Cranford Avenue on-ramp to Kwinana Freeway northbound will remain closed until late November 2021 (subject to change).

    We encourage all road users to follow the signed detour and allow extra time for your journey.
