The Venustiano Carranza distributor at the exit of the city of Saltillo, in the state of Coahuila, requires four curved overpasses with 40-meter spans and variable lengths ranging from 130 to 210 meters.

All of them have been resolved with the same solution; end spans of 25 meters, 2 to 4 central spans of 40 meters, and a width of 9 meters.

The deck is a beam with a variable depth of 1.80 m on supports at 1.00 m in the center of the spans, with a box section in the support zone and a lightened slab with circular cavities in the span centers.

The construction of all of them was done on span-by-span formwork; in each phase, three-quarters of one span and one-quarter of the next were built.
