Ponte Plato - Zambrano Bridge on the Magdalena River, Colombia

The Plato - Zambrano bridge on the Magdalena River in Colombia was constructed to enhance connectivity and facilitate transportation in the region. The construction was completed by a consortium of companies specialized in civil engineering.

The bridge has a total length of 1,073 meters and a roadway width of 8.30 meters, with pedestrian sidewalks each 0.95 meters wide. The deck has a total width of 10.20 meters. It comprises eleven spans of 65 meters, two spans of 55 meters, three spans of 40 meters, and a central span of 130 meters. The central span is constructed with a continuous prestressed concrete box girder of variable section, built using the cantilever method with in-situ cast segments. The rest of the deck consists of 40-meter prefabricated beams, resting on 12.50-meter cantilevers projecting from the 16 piers.

The contract for the project included not only the construction of the bridge but also hydrogeological, hydraulic, environmental, and geotechnical studies necessary to ensure the safety and sustainability of the structure. This bridge is crucial for improving the flow of goods and people, significantly contributing to the economic development of the region.
