Transport Minister Dean Nalder announced the funding for local governments this month, saying it was part of an approach to reduce congestion and �get people home from work faster and safer�.
�The Black Spot program is helping to reduce road trauma and deliver savings to the community in terms of less personal injury and motor vehicle damage,� he said.
The City of Wanneroo will get almost $1.8 million for two projects, while the City of Joondalup will get more than $1 million for three projects.
Wanneroo�s main project will be to realign bends on Old Yanchep Road between Pederick and Trandos roads, seal the shoulder, and install a raised pavement and edge lines.
That will receive $1.78 million in black spot funding, with another $1.19 million included in the City�s 2015-16 budget.
The state funding includes another $16,667 to upgrade lighting on Ocean Keys Boulevard and Pensacola Terrace in Clarkson.
Joondalup will receive $500,000 each for its projects to improve the intersections of Marmion Avenue with Whitfords Avenue and with Hepburn Avenue.
Both projects will include extending turning pockets, with a double left-turn lane to be created on Whitfords Avenue approaches and double right-turn lanes on the southern approach to the Hepburn Avenue intersection.
Another $96,000 in state funding will go towards upgrades at the junction of Joondalup Drive, Grand Boulevard and Hodges Drive, including an extension to the left-turn pocket for northbound traffic.
The Federal Black Spot program for 2015-16 included $310,000 to upgrade the intersection of Marmion and Shenton avenues and $246,000 to upgrade lighting at the Joondalup Drive and Shenton Avenue intersection.
It also allocated $200,000 to build an acceleration lane on Marmion Avenue for traffic coming out of Rochester Drive in Mindarie and $25,000 to upgrade lighting at the intersection of Ocean Keys Boulevard and Key Largo Drive.
Another $15,000 was allocated to modify traffic signals at the intersection of Whitfords and Dampier avenues.
Through the Federal Roads to Recovery program, the City of Wanneroo will get almost $2.35 million this financial year, while the City of Joondalup will receive more than $1.96 million.
