The Puente San Pedro Analco is Mexico's tallest reservoir bridge. The narrow, 2-lane steel beam bridge became necessary from the construction of the massive La Yesca dam. The 208 meter high earth dam is the 2nd highest in Mexico and the 5th highest in North America. Inaugurated on November 6, 2012, the dam created a deep reservoir that inundated a local road that once crossed the Santiago River and was the only way to reach several small villages including San Pedro Analco.

The bridge is part of a complete upgrade to the local Hostotipaquillo-San Pedro Analco road with a length of 43 kilometers. When the reservoir was full at the end of 2012, the tall piers of the San Pedro Analco Bridge became hidden beneath water more then 100 meters deep.

The 342 meter long bridge has a span configuration 35.5 meters, 36 meters, 3 spans of 72 meters and one of 53.5 meters. The roadway is 6.6 meters wide with the total deck width measuring 7.5 meters. The steel beam spans are generally made up of sections 12 meters long. The 3 main spans each required 6 sections.
