Problem The existing two-lane section of the Princes Highway between Jervis Bay Road and Hawken Road experiences safety, congestion and reliability issues due to increasing traffic volumes, including freight and tourism, with peak demand forecast to exceed capacity by 2040. 

Strategic Fit 

The case for change is strong, with safety, congestion and reliability issues expected to worsen without intervention. The corridor is also a critical evacuation route during bushfires, floods and other natural hazards. Increased capacity will reduce closure risk, support evacuation flows, and improve incident management, addressing vulnerabilities that previously led to prolonged disruptions, community isolation and economic impacts. The upgrades will support housing demand and regional growth through improved connectivity and amenity. 

Societal Impact 

The project is expected to improve living standards in a rapidly growing region by reducing congestion and improving travel times. The project will provide enhanced road safety and better access for road users, cyclists and pedestrians, particularly during peak and holiday periods. 

Deliverability 

The project is well progressed, with delivery readiness activities underway across property acquisition, planning and environmental approvals. The proponent has demonstrated capability to deliver the project and internal governance and risk management arrangements are in place. Material residual risks remain, particularly related to contaminated land, planning approvals and property acquisition, and contingency and scope is likely to be revised as investigations and approvals progress. 

Next Steps 

We recommend the Australian Government establishes appropriate governance with the NSW Government to monitor risks related to cost and or scope changes as the design matures in response to contaminated land investigations, planning and environmental approvals.
