Inauguration of the Conagua Viaduct. Engineering and sustainability to preserve the Tacubaya Ravine.

Last February 2, President Claudia Sheinbaum inaugurated the Santa Fe – Observatorio railway section, with which the Interurban Train “El Insurgente” finally completes its Mexico – Toluca route and in which the “Manantial Conagua” Cable-stayed Viaduct stands out, This work was executed by ICA Ingenieros Civiles Asociados and Grupo IDINSA, Freyssinet, Puente Manantial, SGS and where CFCSL was in charge of the structural design and geometric control of the viaduct together with our partners Pontix.

The Viaduct, with a total length of 515 m, was designed with a main span of 200 m in order to preserve the Barranca de Tacubaya Natural Protected Area without touching its soil, protecting the vital spring that supplies thousands of families in Mexico City. The main V-shaped towers have heights of 65 and 75m respectively, supporting 104 suspenders distributed in 8 arches of 13 suspenders each. Each stay is made up of between 29 and 65 strands.

The structure stands out not only for its dimensions, but also for its curved design and the use of an advanced anti-seismic system with shock absorbers.
This project is an example of how civil engineering can be integrated with respect for the environment to transform and increase the competitiveness of a region.

Congratulations to all the technical and construction teams that made this great challenge possible!
