Baldivis Road and Kulija Road Intersection Upgrade

Project summary

We're upgrading the existing intersection at Baldivis Road and Kulija Road to have new traffic signals and an additional westbound lane.

Due to rapid development in the area and known safety risks at the Baldivis Road/Kulija Road intersection, the City, in collaboration with Main Roads WA, completed a feasibility study in 2024/2025. The study, finalised in March 2025, identified the preferred upgrade option as the installation of traffic signals and a new westbound lane. This led to a $7 million commitment from the State Government to fund the project.

The upgrade is scheduled for delivery by March 2029 and will be fully funded by the State Government, although the City may be required to cover any cost overruns.

Why does Baldivis Road/Kulija Road Intersection need to be upgraded?

The current layout was built as part of the Kulija Road construction in 2014. Since then, increased traffic volumes, the staggered intersection design and the steep grade of the Baldivis Road approach have led to significant congestion and a high number of crashes in the area. 

What is the Scope of Project?

The project scope includes installing traffic signals at the intersection and constructing an additional westbound lane that extends through the signals to a safe merging point.

What is the source of Project Funding?

The State Government made an election commitment in 2025 of $7 million dollars to fund the modelling, design and construction of the intersection upgrade.

What are the timelines of the Project and how will traffic be managed during the construction phase?

Prior to construction, the Traffic Modelling and Design of the intersection needs to be finalised, we expect these to be finalised by the end of the 2025/2026 financial year.

Construction is expected to commence in early 2027/2028, to accommodate design timelines for other service providers such as Western Power.

Will there be traffic delays due to the project?

Due to the nature of the construction works, we expect there to be some delays to motorists during the construction phase. Traffic Management will be in place to ensure the works are carried out safely and in a timely manner.

Closures may be required for the project, with appropriate detours in place. Notice will be given prior to any major closures.

What are the major benefits of the upgrade?

The project will greatly reduce the likelihood and severity of crashes at the intersection as well as improve congestion issues.
