• Lagoon Creek Cycle Bridge

  • AllenCon was awarded this project by Moreton Bay Regional Council – a repeat-business client – to construct a 60m, four-span pedestrian and cycle bridge to replace the original creek crossing that had been subjected to regular flooding.

    The location of the project necessitated a unique design approach to ensure that the structure blended into its natural surroundings as much as possible. AllenCon utilised 220 precast concrete planks that simulate the effect of a timber boardwalk and therefore minimised any negative aesthetic impact of the bridge.

    The bridge was constructed to full Disability Discrimination Act compliance and now enables both pedestrians and the local cycling community to cross Lagoon Creek safely and securely year round regardless of weather conditions.

  • The main span over the creek is a 16Tonne steel truss, which was fabricated in 9 separate sections to allow for the galvanizing process to take place. To combat the restrictive access and poor ground conditions on the site, these sections were assembled and launched into position across the creek on temporary falsework and industrial skates.

    The bridge consists of five reinforced concrete pier/abutments placed on piles cast insitu ranging from 750 - 950mm diameter. The sub-structure pilecaps have a concrete volume of 340m3 and each of the three approach spans comprise twin 610mm Universal Beams.
