UPDATE, October 24: WORK to install piers for the Wanneroo Road-Joondalup Drive flyover is planned this weekend.

Main Roads has advised it will start installing the top of the two piers on the eastern side of the intersection on Friday night and Saturday morning.

It said the roads would remain open, but there would be lane closures, and night works would start after the evening peak period for traffic.

“Residents may hear the works, but there should be no vibrations,” a Main Roads update said.

EARLIER: THE State Government has released an artist’s impression of the Joondalup Drive flyover at the Wanneroo Road interchange.

Transport Minister Rita Saffioti said progress on the $50 million project had been steady.

Wanneroo MLA Sabine Winton said the “teething problems” that some motorists felt after traffic signals were replaced with a temporary roundabout in July had eased.

“The temporary roundabout took some adjustment; people took a while to get used to it,” Ms Saffioti added.

Ms Winton said Main Roads had used signs and traffic signals during peak periods to help with traffic flow, and a police presence helped ensure people kept to the speed limits.

Ramps are being back-filled on Joondalup Drive for the flyover.

Main Roads spokesman Dean Roberts said work in the past month had focused on progressing the mechanically stabilised earth (MSE) walls on both sides of the new bridge, installing reinforcement for the piers and pouring concrete for the piers.

Mr Roberts said there had also been tunnel boring for the Water Corporation’s groundwater replenishment pipeline.

“The MSE walls are currently being backfilled with more than 50,000 tonnes of material, which will be compacted into 35cm layers,” he said.

“In addition, bridge piers are currently being installed between the two ramps in the middle of the roundabout.

Piers being installed in the roundabout at Wanneroo Road-Joondalup Drive.

“Installation of the Water Corporation groundwater replenishment pipeline will continue, while pavement will be laid on the north-west corner of the intersection, allowing traffic to be moved further north.

“This will allow the final MSE panels to be installed on the western side of the bridge.”

Mr Roberts said the pier installation was due to finish in November and bridge beams would be progressively delivered to site over the coming months and were due to be installed by the end of the year.

“The installation of the bridge beams will require road closures,” he said.

“Once details of the installation are confirmed we will communicate extensively with the local community.”

Work is expected to finish in mid-2020. Visit for more information.
