The Shire of Serpentine Jarrahdale is getting on with the job of fixing problem roads through this year’s Road Renewal Program, a $10.6 million initiative that will upgrade some of the Shire’s most worn and damaged streets.

Rapid population growth, busier roads and heavier freight traffic have put extra pressure on roads not designed or built for today’s traffic. The Shire is acting to make roads safer, more reliable and better able to support future development.

The program will deliver resurfacing and upgrades on busy connector roads and local streets, safety improvements at key intersections, and gravel re-sheeting on rural roads. Works will be staged and are expected to finish by June 2026.

The program is funded through a combination of Shire contributions and State and Federal grants. The State Government is contributing just over $3.2 million, the Federal Government just over $5 million, and the Shire just over $2.4 million, bringing the total investment to just over $10.6 million.

Projects are prioritised using the Shire’s Roads Forward Works Plan and condition assessments to ensure roads are renewed at the right time and more costly repairs are avoided.

The Shire continues to advocate to State and Federal Government for funding to repair its roads, receiving a $17 million commitment from the State Government for its Hypergrowth Roads Program at the last election.

Partnerships with organisations such as National Growth Areas Alliance (NGAA) are key to securing roads funding at State and Federal level.

Comments attributable to Shire President Rob Coales:

"The Shire is responsible for maintaining, renewing and upgrading 661km kilometres of sealed roads and 152 kilometres of unsealed roads, a road network with replacement value of around $457.6m million.  

“This program is about getting on with the job of delivering safer, stronger roads for the community. While there will be short-term disruptions, these works are a long-term investment that will protect our roads, reduce future costs and support the rapid growth of Serpentine Jarrahdale.

“We thank the State and Federal Governments for their support in making these upgrades possible. The Shire is making it happen for residents and will continue to advocate strongly for the infrastructure funding the community needs.”

Comments attributable to National Growth Areas Alliance (NGAA) CEO Bronwen Clark

“NGAA consistently advocates for increased and more targeted Federal investment in local and state road infrastructure, recognising that outdated road networks in fast-growing communities, like Shire of Serpentine Jarrahdale, are constraining access to jobs, services and economic opportunity.

“As population growth continues to outpace infrastructure delivery, congestion is becoming a significant drag on national productivity.

“Growth areas are doing the heavy lifting of population growth, yet their road networks were never designed for the volumes they now carry.

“Without sustained investment to upgrade these corridors, we risk locking communities out of opportunity and undermining productivity across the broader economy.”
