Heavy Rainfall Causes Infrastructure Failure and Road Closures in Puente Alto

The Chilean Meteorological Service (DMC) warned that heavy rainfall was expected to exceed the drainage capacity in Puente Alto. By 9:00 PM local time, the infrastructure failure resulted in physical road blockages and mass power outages, affecting 13,035 subscribers in the Metropolitan Region. The failure point was primarily the Ruta 5 highway, where northbound traffic toward Santiago was reduced to a single lane due to water accumulation.

The overwhelmed rainwater collectors and closed underground passages rendered major routes impassable, physically halting cargo transport. The resulting power outages and road blockages disrupt logistics and access to critical facilities in the area.
