Description
The bridge has three approached spans of 20.2 m length each and two cable-stayed spans of 121 and 60 m. The two main spans are supported by central stays continuous through a steel saddle on top of the tower. All stays converge at the top of the tower as a fan configuration, being one of the few cable-stayed bridges with this cable-stay arrangement. The deck plan is mostly straight with a constant width of 18.6 meters. The deck is a 2.4 m depth tri-cellular concrete box girder and it is suspended by the cable-stays spaced at 12 m. The deck is internally post-tensioned with longitudinal and transverse tendons. The 50 m high central tower is a reinforced concrete tower with a rectangular cross section and variable width in both directions. The pylon is inclined 5° to achieve a more dynamic visual experience and landmark character. The bridge is located in a seismic zone of average degree in Colombia, having calculated for an earthquake spectrum with a maxima acceleration of 5m/s2. The total cost of the structure was approximately US$12 million.Construction
Construction of the bridge began in 2001, and was successfully completed in July 2003. At the time of construction, the bridge was the second largest concrete cable-stayed bridge in Colombia.References
