​Karel Avenue Upgrade

The Karel Avenue Upgrade forms part of a $2.3 billion package of road and rail infrastructure works, funded by the State and Commonwealth Governments and announced by Premier Mark McGowan on 7 May 2017.

The $15 million project comprises upgrades to the Roe Highway and Karel Avenue interchange including widening of the existing Karel Avenue bridge. It will improve access to Roe Highway and Kwinana Freeway for the residents of Leeming and Bull Creek, and remove a bottleneck on the approach to the Jandakot Airport precinct, which when developed, is expected to support in excess of 8,000 jobs and 300 businesses.

Request for proposals issued for design and construction - April 2018

Industry has been issued with requests for proposals for the design and construction of the widening of Karel Avenue bridge across Roe Highway and lengthening of the existing Karel Avenue bridge across the freight rail line immediately to the south of Roe Highway to facilitate construction of the Thornlie to Cockburn rail line as part of Metronet.

As part of the proposal process and subject to available funds, we will also investigate opportunities to widen Karel Avenue between Farrington Road and Roe Highway interchange and south of the Karel Avenue bridge and Berrigan Drive roundabout.
