Local Roads Package
The federal government is investing $200 million in a Local Roads Package, a competitive rounds-based program which allows Western Sydney councils to deliver improved road connections that support the infrastructure plan., round 1 projects are complete and round 2 projects underway or complete, and project proposals for Round 3 projects are currently under assessment. Eligible councils include Liverpool, Camden, Wollondilly, Campbelltown, Penrith, Fairfield and Blacktown councils. An example of the projects was the intersection upgrade of Cumberland Highway at Hamilton Road, St Johns Road and John Street, which was completed under the Local Roads Package after Fairfield Council was granted $5.8 million over two years.
