The Bogotá Metro Line 1 project completed the construction of a 215-meter viaduct at the intersection of Caracas Avenue and 26th Street. ^[1] As of July 31, 2026, the Line 1 project registered an execution progress of 81.25%. ^[2] The viaduct is composed of 40 stones, including two central zero stones and three closing stones that united the two cantilevers. ^[3] The viaduct was constructed using a successive cantilever system, which allows the structure to be raised progressively from supports without installing permanent supports on the ground. ^[4] The bridge features a section of over 200 meters without intermediate columns, a characteristic that reduced interference with the railway tracks below. ^[5] The Empresa Metro de Bogotá stated that the design allowed lifting more than 200 meters of structure without installing intermediate columns. ^[6] The Metro's First Line is currently 81% complete and is scheduled to begin commercial operations in March 2028. ^[7]
