Residents and business owners in Pinjarra are renewing calls for a long-awaited heavy haulage bypass, as hundreds of large trucks continue to travel through the town's main streets every day.

Located about 80 kilometres south of Perth, Pinjarra is home to approximately 6,000 people and sits near major industrial operations, including Alcoa's Pinjarra Alumina Refinery. The town's location means heavy vehicles transporting materials and equipment regularly pass through its centre, creating challenges for road users, pedestrians and nearby businesses.

According to a report published by ABC South West WA on October 2, about 800 heavy haulage trucks travel through the wider Peel region daily, with most passing through Pinjarra's main street. The route runs close to schools, cafes, homes and shops, where residents and visitors share the road with large vehicles.

Shire of Murray president Douglas McLarty said the volume of heavy vehicles was affecting movement through the town. He raised concerns about trucks passing close to parked cars, interacting with traffic lights and creating difficulties for students, parents and caregivers accessing nearby schools.

Local business owner Caris McClements said the noise and size of the vehicles can disrupt everyday activities. Conversations with customers may be interrupted as trucks pass, while oversized loads can cause temporary road closures that delay traffic and affect access to businesses.

The proposal for a bypass is not new. Plans to divert heavy haulage away from Pinjarra have been discussed since the 1990s. In 2022, the project received support involving $50 million in state funding and a proposed $200 million federal contribution. However, the federal government withdrew its share in 2023, and the project remains in the planning and approvals stage. The Western Australian government has maintained its commitment to the project, but a construction schedule has not been confirmed.

The issue has also prompted discussion about the town's future identity and economy. Some residents say a bypass could improve safety and make the centre more comfortable for people who live and work there. Others, however, are concerned that redirecting heavy vehicles could also divert visitors who currently stop to watch the large trucks pass through town.

Pinjarra's heavy haulage traffic reflects the area's connection to nearby industrial activity and regional freight routes. Any future bypass would need to balance the needs of industry and freight operators with the safety, accessibility and economic interests of the local community.

The Shire of Murray and local representatives continue to call for progress on the proposed route. For residents, the central concern is finding a lasting solution to the daily interaction between heavy vehicles and a town centre used by pedestrians, school communities and businesses.

The state government says the bypass remains in the planning and development phase. Until a final decision and construction timeline are confirmed, heavy haulage vehicles will continue to use the existing route through Pinjarra.
