The Jon Sanders Dr, Powis St and Harborne St Intersection Road improvement project aims to enhance safety for everyone, from pedestrians, cyclists, and drivers, while reducing congestion and improving traffic flow.

This busy intersection, surrounded by a primary school, shopping center, and residential areas, experiences heavy traffic but lacks pedestrian crossing lights. Intersections of this nature pose safety risks and contribute to frustration among all road users.

To address these issues, we're implementing a comprehensive design that includes:

• New pedestrian crossing lights on all approaches: Making it safer and easier for pedestrians to cross.
• Additional lanes: Adding lanes on Jon Sanders Drive and Powis Street to improve efficiency and reduce congestion.
• Improved turning lanes: Providing dedicated turning lanes on Jon Sanders Drive and Harborne Street to make turning movements smoother and safer.
• Updated traffic signals: Implementing a "double diamond" phasing system and installing modern traffic signals for better efficiency.
• New shared path: Constructing a 3.0 meter wide shared path connecting Rawlins Street to the Mitchell Freeway PSP (principal shared path) for improved pedestrian and cyclist access.

This project is a collaborative effort between the City of Stirling (The City) and the Town of Cambridge (The Town), supported by funding through a MRRG  Improvement program.

With a the total project value estimated at $3 million and a two-thirds funding commitment through the Improvement Program, The Town of Cambridge and the City of Stirling will each contribute only one-sixth of the total cost each. This represents great value considering the overall net benefit.

The Town is the applicant of the MRRG Improvement fund and is responsible for the administration of the grant and the Town’s Council approvals. The City is responsible for all the project design works and construction management. The Town is providing comment and review on the design with community engagement to be led by the City. The Town will contribute by sharing project information via its various forms of engagement methods. 

Year 1 (2023/2024) and Year 2 (2024/2025):

• Detailed Design,
• Regulatory Approvals, and 
• Enabling works (relocation of existing infrastructure assets). 

Year 3 (2026/2027):

• Construction - The City of Stirling will manage and undertake all construction works and community engagement ready for construction.
