State Government Major Road Projects

The State Government secured more than $552 million for a number of major road projects in Perth's southern suburbs (May 2017). The projects will fix congestion hotspots on major arterial roads through the southern suburban road network and will create more than 4,000 jobs during construction.

Funding for the projects is the result of a Commonwealth-State $2.3 billion funding arrangement that included the full relocation of funding from the cancelled Perth Freight Link.
