Cable Stayed Bridge – Berrinba Wetlands

Ronstan Tensile Architecture supplied and installed the suspension system for the cable stayed bridge in this environmentally sensitive and significant project within a newly created recreation and wildlife reserve. 

Bridge 4, the “iconic” cable stayed bridge of the Berrimba Wetlands, could not impact upstream and downstream flood levels and so affect the natural flow rates in Scrubby Creek. This required large open spans above the 100-year flood levels. While this could have been achieved with the “Berrinba” bridge in multiple spans, it was decided that this should be an “iconic” bridge. A cable stayed bridge was decided as best meeting the needs for striking appearance and longer spans. The cables were Ronstan Galfan 28.3 mm dia spiral strand – 1×37 open spiral fitted with Ronstan type 3 fork/swage turnbuckle at one end and a swage fork at the other. These were chosen as they should give a longer life than normal galvanised cables. The cable fittings also had an undeniable architectural appeal.
