What Happened at Puente de la Concordia?

On September 10th, a gas tanker carrying approximately 49,500 liters of LPG (liquefied petroleum gas) overturned and exploded on Calzada Ignacio Zaragoza, near Puente de la Concordia in Iztapalapa.

Initial reports suggested the vehicle was traveling at excessive speed and lost control while entering a curve on the Mexico-Puebla highway. This caused it to collide with exterior and interior containment walls, resulting in the rollover. One of these impacts created a 40 cm tear in the tank, allowing gas to leak before igniting.

Despite the dispersing gas cloud, drivers and pedestrians continued through the area. Once ignited, the gas cloud expanded approximately 180 meters, causing immediate fatalities.

Ongoing Investigations

Besides excessive speed, potential safety measure violations in transporting hazardous materials were mentioned. Authorities initially blamed road conditions for vehicle destabilization, which the Mexico City government denied. However, a new video emerged showing the gas tanker traveling at normal speed, contradicting authorities’ claims.

Investigations have been opened for culpable homicide, culpable injury, and property damage. Additionally, a Solidarity Committee was established to coordinate support for the victims.
