On May 3, 2021, a combination of wear and tear and the structural damage that was caused during the 2017 Mexico City earthquake, caused the overpass to collapse into the busy street below. 26 lives were lost, 79 people were hospitalized and 22 others were reported missing, making this accident the deadliest one that the Mexico City Metro had seen in almost 5 decades.
