Overview

• The collapse occurred near km 177 on the Quiroga–Tepalcatepec route between Cuatro Caminos and Apatzingán, exposing infrastructure linked to a subsurface irrigation flow.
• Authorities reported an affected stretch roughly 30 meters long, about 3 meters wide and 1.5 meters deep, with no injuries confirmed.
• Traffic is moving in both directions using the shoulders with alternating flow, and officials say there is no official alternate route.
• SCOP cited recent heavy rains and a detached slab from an older roadway structure as the origin, based on information from the SICT center.
• The concessionaire for the segment is carrying out continuous work, focusing on stabilizing the site before filling, while drivers are urged to follow Guardia Nacional updates and proceed with caution.
