Project update

Upcoming out of hours works

Wanneroo Road and Joondalup Drive intersection

  • 19 August to 28 September, 7pm to 7am
  • 1, 8, 15 and 22 September, 8am to 5pm
Bridge construction underway

During August 2019, we will start building the footings and installing the piers and abutments in the roundabout, and on either side of the roundabout along Joondalup Drive. There will be short term road closures after hours to ensure the installations are completed safely. Read more in the August Project Update

Traffic switch complete

Following a full closure, the intersection of Wanneroo Road and Joondalup Drive is now operating as a temporary roundabout. 

As with any change in road layout, we encourage road users to be vigilant, approach the roundabout at the appropriate speed and give way to the right. Traffic volumes on Wanneroo Road during the afternoon PM peak period will be carefully monitored and temporary traffic signal will be activated if necessary to regulate traffic flow.

To see how the intersection was reconfigured in the space of one weekend, watch our latest timelapse footage.

Roadworks update

Road users may experience some delays during peak times. We encourage road users to avoid the works area where possible and consider using alternate routes, such as the Neerabup Road exit off the Mitchell Freeway or Pinjar Road off Wanneroo Road.
