Itecsa participated in the Mexico City comprehensive transportation and circulation general program, on the western area. It includes six projects that will function from North to South and vice versa: of these, Itecsa was responsible for the construction of the twin tunnels on the Alta Tensión Avenue, built along Eje 5 Poniente and under Centenario Avenue. They have two lanes each way and an approximate length of 971 ft and 1 040 ft, respectively, of which Itecsa built 50% through the south portal. The cross section includes two roadways and shoulders.

As part of the same project, the underpass between avenues Rómulo O’Farrill and Barranca del Muerto was built, with 545 pilings of a 3.94 ft diameter cast on site, that serve as foundations for the beams and roadway slabs, as well as retainers for the excavation trench. Technically one could say that in fact four tunnels were constructed, because each of them has a different entrance.

This project benefits more than a million people, since it configures a connection between the south and west of the city. The tunnels were designed to have a useful life of 20 years, in addition to being the longest ones dug in the Federal District for vehicle circulation.
