Upgrade works have begun at the Tonkin Highway and Dunreath Drive intersection near Perth Airport, aiming to ease congestion in the airport precinct.
The works will modify the existing Tonkin Highway southbound off-ramp to provide a dedicated turn lane into Dunreath Drive, with the northbound off-ramp improved by part-time roundabout metering.
Unlike normal traffic signals, the new metering signals on the roundabout only operate when traffic builds up – at all other times normal roundabout rules apply. This creates gaps in traffic, helping to ease congestion and solve excessive queuing and delays during peak periods.
Over 14,000 vehicles use the Dunreath Drive off-ramp every day with this number expected to climb by at least 30 per cent with the opening of Perth’s first Costco in the area, later this year.
WA Transport Minister, Rita Saffioti, said that she was confident of the upgrade’s benefits for Perth.
“Perth Airport is already a hub of activity in its own right, and with new developments, including the new Costco, traffic in the area will increase.
“These upgrades will improve traffic flow, and along with the Forrestfield-Airport Link which is due to open in late 2021, will help ease congestion around this important precinct.”
Belmont MLA, Cassie Rowe, highlighted the benefits for local communities.
“With more than 14,000 vehicles using this intersection every day, and this expected to grow 30 per cent with the opening of Costco, these upgrades are very timely and will help local residents spend less time on the road and more time with family and friends.”
Construction is now underway, with completion expected later this year.
