The Karel Avenue upgrade will see the removal of the bottleneck on the approach to Jandakot, reducing the congestion at the Karel Avenue and Roe Highway interchange, and improving access to Roe Highway and Kwinana Freeway for Leeming and Bull Creek residents.

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

  • After hours work scheduled for April

    Works on the Karel Avenue Upgrade Project are progressing and after hours works will be required between Thursday 1 April until the end of the month to deliver the next stages of the project safely and efficiently.

    We thank you for your patience during this busy period ahead.

    The after hours works will include erecting formwork and placing steel reinforcement prior to pouring concrete for elements of the rail bridge across Karel Avenue.

    This work will be carried out after hours to allow for lane closures or other traffic management arrangements, which would cause significant traffic impacts if implemented during the day.

    There is a planned road closure of Karel Ave (between Roe Hwy and Pilatus) from 7pm Thursday 1 April to 5am Tuesday 6 April to facilitate bridge concrete works that cannot be completed during the day.

    Detours are as follows:

    • Karel Avenue southbound to Jandakot: Access Kwinana Freeway South from Roe Highway and exit left at Berrigan Drive.
    • Northbound to Murdoch: Use Pilatus Street when travelling on Karel Avenue westbound to access Berrigan Drive and Kwinana Freeway north towards Roe Highway.

    Extensive detour signage will be in place.
