The Carrera Novena viaduct in Bucaramanga is situated over a wooded area of great environmental importance which must be respected. The proposed viaduct with a principal span of 292.4m and two compensation spans 129.2m long. The maximum height over the ravine is 75m and the piers of the viaduct have heights of 52m and 72m; for this reason singles piers have been used, over which the towers have been built which stay the deck in its axis. It is 30m wide because 6 lanes of traffic and 2m wide pedestrian walkways were planned. The structure of the deck is formed of a singlecell box girder with a trapezoidal section and a depth of 2.8m. This girder is extended laterally by slabs. Its width creates significant bending moments which are resisted by interior transverse triangulations and exterior struts every 3.4m. It is situated in a zone of high seismic activity and for that reason a structure has been adopted which is encastred in the piers and free in the abutments. It was constructed using successive compensated cantilevers, and concreted in situ.
The Vidalta Bridge is located on the outskirts of Mexico City, in a very deep valley with special conditions, which led to the creation of a unique cable stayed bridge.
