Overview

• Authorities report round‑the‑clock work with 40 workers in three shifts, and six of eight pipe sections installed as of Monday.
• The collapse measured roughly 14 meters long and 5 meters deep on Calzada Ignacio Zaragoza in Iztapalapa.
• Officials attribute the failure to a fracture in the deep drainage collector, prompting replacement of eight 1.5‑meter‑diameter reinforced concrete sections.
• A 20‑meter stretch was excavated while the subsoil is being replaced and compacted to withstand heavy‑vehicle vibrations and prevent future failures.
• The city says the fix will improve stormwater discharge, with full reopening expected Sunday after backfilling and resurfacing.
