Sustainable design for Swale bridges in Townsville

In recent weeks, the Townsville Council has undertaken a commendable initiative by installing swale bridges across the city. These bridges, designed to facilitate water flow and mitigate stormwater runoff, not only serve their functional purpose but also embody the principles of sustainability and environmental responsibility. In this blog post, we will explore the innovative use of recycled plastic materials in the construction of these swale bridges and the positive impact they have on Townsville's infrastructure.

Utilising Recycled Plastic Materials for Bridge Construction

A notable aspect of these swale bridges is their construction material. The swale bridges are made using recycled plastic Enduroplank™, a durable and sustainable alternative to traditional materials like timber or concrete. By repurposing plastic waste, the Townsville Council, in collaboration with Repeat Plastics Australia Pty Ltd, has not only reduced the environmental impact of construction but also contributed to the circular economy by giving new life to recycled materials.

Advantages of Recycled Plastic Enduroplank™

The choice of recycled plastic Enduroplank™ offers several advantages:

  1. Durability: Recycled plastic is highly resistant to rot, termites, and weathering, ensuring the longevity of the swale bridges. This reduces the need for frequent maintenance and replacement, resulting in cost savings for the council in the long run.
  2. Environmental Impact: By using recycled plastic, the council minimises the extraction of natural resources and the production of new materials. Additionally, the utilisation of plastic waste helps divert it from landfills, reducing pollution and promoting a cleaner environment.
  3. Safety and Accessibility: The swale bridges are designed with safety and accessibility in mind. The carefully planned dimensions and construction ensure a sturdy and reliable structure, accommodating pedestrians, cyclists, and small vehicles while maintaining a safe crossing for water flow.

In addition to their functional benefits, the swale bridges contribute to the overall aesthetic appeal of Townsville. The use of recycled plastic Enduroplank™ provides a visually appealing finish that blends harmoniously with the natural surroundings. The bridges serve as attractive landmarks and focal points within the community, enhancing the city's charm and fostering a sense of pride among residents.

The installation of swale bridges by the Townsville Council is a significant step towards sustainable infrastructure development. By choosing recycled plastic Enduroplank™ as the construction material, the council showcases their commitment to environmental responsibility, and circular economy principles. As other cities seek innovative solutions for their infrastructure needs, Townsville stands as an inspiring example of integrating sustainability into urban development.



Enduroplank™ is a sturdy long lasting and virtually maintenance free decking product that provides an ethical alternative to timber. It is ideal for a myriad of commercial applications and is especially suitable for marine environments as salt water will not corrode the material.
