Intersection upgrades underway for Perth Airport link

Construction is expected to begin on the $215 million Mitchell Freeway extension to Romeo Road by late 2020 following the Western Australian Government’s $107.5 million commitment.Work has begun upgrade the busy off-ramps to Perth Airport to reduce congestion. The works include upgrades at the Tonkin Highway and Dunreath Drive intersection.

Construction 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.

The new metering signals on the roundabout only operate when traffic builds up, at all other times normal roundabout rules apply. This measure is hoped to create gaps in traffic, to ease congestion and solve excessive queuing and delays at peak hours.

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.

Transport Minister Rita Saffioti said 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,” Ms. Saffioti said.

Construction on the intersection is underway now and is expected to be completed mid-2020.

The project is jointly funded by the State Government and Perth Airport.
