Seib & Eumundi Pedestrian Bridge and FRP Boardwalk

DM Composites was engaged to design and construct the Seib Road Pedestrian Bridge and 300-metre FRP boardwalk in Eumundi, QLD, delivering a flood-resilient, visually discreet infrastructure upgrade that enhanced pedestrian safety, preserved the local riverside environment, and minimised community disruption through innovative offsite assembly.

LOCATION

The town of Eumundi in the Sunshine Coast hinterland had long called for safer pedestrian infrastructure along the busy Eumundi-Noosa Road. For decades, locals and visitors shared a narrow road bridge with vehicular traffic, facing daily safety risks with less than a metre of shoulder for walking or cycling. After repeated community lobbying and as part of a broader road safety upgrade, the $6 million Seib Road Pathway Project was initiated. This landmark development comprises a new pedestrian bridge and a nearly 300-metre-long FRP (Fibre Reinforced Polymer) boardwalk, delivering a safe, accessible, and sustainable pathway across the North Maroochy River.

OUTCOME

DM Composites successfully delivered the full design, supply, and erection of both the pedestrian bridge and FRP boardwalk system, showcasing a true turnkey delivery. The 38-metre single-span steel truss bridge was pre-assembled offsite and installed in a single overnight lift, minimising disruption and environmental impact. The adjoining 300-metre FRP boardwalk featured lightweight substructure components, anti-slip decking, and an innovative collapsible handrail system tailored for flood resilience. This project demonstrated DM Composites’ technical excellence and capacity to execute complex infrastructure in sensitive environments—enhancing public safety, improving local connectivity, and setting a new benchmark for sustainable pathway solutions in regional Australia.

CHALLENGES AND Solutions

  • Flood Resilience: Located in a flood-prone river zone, the boardwalk was designed to minimise hydraulic resistance. The absence of in-stream piles for the bridge reduces waterway obstruction and upstream flood risk.
  • Community Impact: Prefabrication and overnight installation minimised road closures and local disruption, with extensive coordination to achieve a seamless lift operation.
  • Environmental Stewardship: All cutting and sealing of FRP materials was completed offsite, preventing microplastics release into waterways. Installation crews adhered to strict erosion and sediment control measures throughout the works.
