Piling is now under way for the new cable-stayed bridge over the Magdalena River in Colombia. The two-tower cable-stayed bridge will have a 240m main span and two back spans of 75m each. The deck, 16.3m wide, will accommodate 2 traffic lanes and will be suspended on two lateral cable planes. The deck consists of two lateral pre-stressed concrete girders 1.2m in depth, which are supported by the stays spaced at 10m. In the transverse direction, the longitudinal girders will be connected with concrete transverse beams 5m apart. The towers, which will be 39m high over the deck level and will consist of two concrete inclined pylons connected with transverse concrete girders. The abutments will take the back stays uplift force allowing the longitudinal movements of the deck. Construction of the main span will be carried out using the balanced cantilever method to reduce construction impact on the river.
