The Karel Avenue bridge over Roe Highway will be widened to create a dual carriageway, and also extended across the freight railway line south of Roe Highway to facilitate the construction of the Thornlie-Cockburn Link as part of METRONET.


  • Improve traffic flow and access to Kwinana Freeway and Roe Highway
  • Remove bottleneck on the approach to Jandakot Airport
  • Support the development of the Jandakot Industrial Area

Detour options

  • Restricted access at Roe Highway Karel Avenue interchange

    Until 5am on Saturday 7 November, there will be no right turn access to the Roe Highway east-bound entry ramp from Karel Avenue north-bound.

    The Karel Avenue off ramp from Roe Highway east-bound is now also closed. This change was made following safety concerns, and signage will be placed on Kwinana Freeway to alert drivers.

    Traffic heading south on Karel Avenue after Farrington Road will still be able to access Roe Highway east-bound, as will traffic heading east on Roe Highway after coming off Kwinana Freeway.

    Detours will be in place to access Roe Highway from Kwinana Freeway or South Street, and to access Karel Avenue south-bound via Farrington Road or Berrigan Drive.

    The best way to reach Jandakot Airport and the adjacent industrial area is via Berrigan Drive and Pilatus Street.

    Restricted Access Vehicles south of Roe Highway should avoid travelling north on Karel Avenue.
