Shocking security video coming out Mexico City shows the moment when a metro overpass collapsed, killing at least 24. 

According to authorities, over 70 people were injured as a result of the overpass collapsing. Nearly 50 of those injured were transported to a local hospital with roughly seven of them considered to be in serious condition. 

The Monday night collapse of the overpass was one of the deadliest in the metro's history. However, Mexico City Mayor Claudia Sheinbaum noted that the deaths were lessened as a result of the location of the accident. According to Sheinbaum, the concrete median strip helped limit the damage that could've been caused had the collapse occurred elsewhere on the metro route.
