Vaisigano Bridge

Vaisigano bridge is significant junction within Samoa’s civil infrastructure as it connects the east coast to the central township. With increased tropical cyclones and flooding, the previous bridge was deemed unsafe and JICA funded the construction of a contemporary fit for purpose bridge. The bridge is a 75m three span PC interconnected hollow slab bridge with an estimated 40m depth design to last 100 years. The bridge is 1.5m higher than the previous bridge for greater resilience. CaBella was engaged by Konoike Construction to complete precast concrete work on a offsite facility for quality control and accuracy, in-situ placement of concrete elements and pillar and abutment construction. Other challenges included piling down 40m whilst reducing the amount of water, the site being located at the bottom of a valley which is prone to significant water flows. The successful completion of this project has transformed the Vaisigano area and provided Samoa with a more resilient high-quality investment to combat the impacts of Climate Change.
