The 2,750m-long Chacao Bridge, South America’s longest suspension bridge, will connect mainland Chile with the country’s largest island Chiloe. The three-tower suspension bridge will have main spans over 1km in length (one 1055 m and the other 1155 m). The central pylon with inverted V shape shown in the reference design has been modified by SYSTRA. The bridge being located close to an active seismic fault, particular care was considered on seismic robustness, and many specific seismic analysis were performed. The total length of the suspended steel superstructure is 2494 m and the weight about 21,000 tons. The bridge girder is continuous from the South pylon to the North abutment. |
