In an effort to tackle some of the most congested roads in Perth, the State Government has allocated more than $100 million in the State Budget to road upgrades in the northern suburbs.
Among the funded works is a $35.9m program to upgrade key sections of Wanneroo Road.
This includes additional right and left turn lanes and extensions at Warwick Road, as well as median widening at Hepburn Avenue and Wanneroo Road to enable double right turns.

It also covers advanced detector loops for improved queue detection and signal optimisation at Gnangara Road, realignment works near East Road to improve sight lines, and planning for a future interchange at the Whitfords Avenue–Gnangara Road connection.
Other funded works include a $3.5m contribution to build a roundabout at the intersection of Craigie Leisure Centre and Whitfords Avenue and to create a new access road into Pinnaroo Valley Memorial Park, to be delivered by the City of Joondalup.
Headlining the $113.4m funding package is an initial $70m allocation towards the grade-separated intersection project at Erindale Road and Reid Highway.

According to Main Roads WA, the intersection on the critical east-west corridor ranks as the worst in the State for congestion, with lost productivity estimated to have cost the WA economy $21.3m during the 2023–24 financial year.
Deputy Premier, Treasurer and Minister for Transport Rita Saffioti believes the upgrades will ease traffic and improve safety on roads in the northern suburbs.
'Right across Perth's north, we're investing in key projects that will improve the road network and make it safer and more efficient for everyone to get around,' Ms Saffioti said.
'We recognise that improving our road network and busting congestion is important to Western Australians and important to the productivity of our economy.'
The Reid and Erindale junction is the only remaining at-grade intersection between Tonkin Highway and Mitchell Freeway.
Since 2019, the number of vehicles using the intersection each day has climbed by around 10 per cent. Traffic is expected to grow from 60,000 to nearly 111,000 vehicles daily by 2054.
Major work on the new interchange is scheduled to begin in 2028-29.
