Project summary

The intersection of Baldivis Road and Kulija Road is being upgraded to improve safety, traffic flow, and capacity as the Baldivis area continues to grow.

The upgrade will include the installation of traffic lights, additional turning lanes, and extra road capacity to help reduce congestion and improve safety for all road users.

About the Project

As more people move into the area, traffic volumes at the Baldivis Road and Kulija Road intersection have increased. The City worked with Main Roads WA to investigate ways to improve safety and traffic movement through the intersection.

A study completed in March 2025 identified traffic signals and additional lanes as the preferred solution. Following further investigations and design work, the project scope has been confirmed.

What is included in the upgrade?

The project will deliver:

  • New traffic lights at the intersection
  • An additional lane for westbound traffic on Kulija Road from Kwinana Freeway to west of the intersection
  • An additional lane for eastbound traffic on Kulija Road from the Baldivis Rd intersection to Kwinana Freeway
  • An additional right-turn lane from Baldivis Road heading east
  • An additional left-turn lane from Kulija Road heading south
  • A dedicated left-turn lane from Baldivis Road heading west

These improvements will help increase the capacity of the intersection, improve traffic flow, and create a safer road environment.

Please refer to the project drawing for detailed design information.

Project Funding and Timeline

The project is funded through a $7 million commitment from the State Government. 

The construction is expected to commence in the 2027/2028 financial year. The conditions of the funding require the project to be complete by March 2029. Please refer to the timeline below for further information. 

Due to the projects reliance on multiple external stakeholders there is a risk that delays or changes to works undertaken by external utility and service providers required to support the project may impact critical project milestones in schedule delays, additional costs and disruption to project delivery. 

The Baldivis Road and Kulija Road intersection was built in 2014. Since then, the local area has grown significantly, resulting in more vehicles using the intersection every day.

The current layout can become congested during peak periods and has experienced a higher number of crashes than expected. Upgrading the intersection will help improve safety, reduce delays, and support future growth in the area.

The upgrade will include:

  • New traffic lights at the intersection
  • An additional lane for westbound traffic on Kulija Road from Kwinana Freeway to west of the intersection
  • An additional lane for eastbound traffic on Kulija Road from the Baldivis Rd intersection to Kwinana Freeway
  • An additional right-turn lane for vehicles travelling east on Baldivis Road
  • An additional left-turn lane for vehicles travelling south on Kulija Road
  • A dedicated left-turn lane for vehicles travelling west on Baldivis Road

Please refer to the project drawing for more detailed design information.

The project is funded through a $7 million commitment from the State Government, announced in 2025.

This funding will support the planning, design and construction of the intersection upgrade.

The project is currently in the planning and design phase.

Detailed traffic modelling, design work and approvals are expected to be completed by the end of the 2026/27 financial year. Construction is currently anticipated to begin during the 2027/28 financial year, subject to approvals and coordination with utility providers, including Western Power, ATCO Gas, Main Roads WA and other stakeholders.

The project is currently scheduled to be completed by March 2029.

Construction works will be carefully planned to minimise disruption wherever possible. However, some traffic delays are expected while works are underway.

Traffic management measures will be in place to help maintain safe access through the area. Temporary lane closures, changed traffic conditions and occasional road closures may be required at certain stages of the project.

Residents and road users will be notified in advance of any major traffic impacts or road closures.

Some traffic delays are expected during construction due to the nature of the works.

The City will work with contractors to minimise disruption and maintain traffic flow wherever possible. Traffic management and detour routes will be clearly signposted when required.

The upgrade will:

  • Improve safety for all road users
  • Reduce the risk and severity of crashes
  • Improve traffic flow through the intersection
  • Help reduce congestion and delays
  • Support continued growth in the Baldivis area
  • Improve the overall efficiency of the local road network

These improvements will create a safer and more reliable intersection for residents, businesses and visitors.
