Overview

• The collapse on Calzada Ignacio Zaragoza in Iztapalapa measures roughly 14–15 meters long and about 5 meters deep.
• Officials attribute the sinkhole to a break in the deep drainage collector requiring replacement of eight 1.5‑meter‑diameter pipes.
• Jefa de Gobierno Clara Brugada and water agency chief Mario Esparza are supervising 24/7 works on site.
• Crews opened a 20‑meter section, stabilized and replaced soil to resist heavy truck vibrations and prevent future failures.
• Authorities say traffic could be restored by next Sunday once reconstruction and backfilling are complete, with contractors pledging continuous shifts and higher‑grade materials.
