The deadliest bridge and building collapses

The Chirajara Bridge was intended to connect two tunnels between Bogota and Villavicencio. But as the two sections were being put together in January 2018 one of the pylons broke away, killing nine people. Investigators pointed to a construction error, which meant the other section was also in serious danger of collapsing. The bridge was ultimately blown up in July (pictured).

Workers were renovating the Studenka Bridge in August 2008 when it suddenly collapsed. Just as it fell away, however, a speeding train was headed towards the scene of the accident. Traveling at 120 kilometers per hour (75 mph), the train plunged into rubble below. It remains unclear what exactly caused the collapse, but investigators have since found several faults in the construction.

The 580-meter (1900 feet), eight-lane bridge in Minneapolis was a crucial artery between two city districts. Renovation work began just days before the collapse on August 1, 2007. Even though just one lane was open at the time, 13 people were killed in the accident. Investigators said a construction error led to the bridge caving in.

It only took a matter of seconds for the Sampoong Department Store in Seoul to collapse in on itself on June 29, 1995, killing more than 500 people. A probe uncovered a spate of building violations: several regulations were ignored, the building was shoddily constructed and several of the wrong building materials were used.

The collapse of the Rana Plaza in Bangladesh's Dhaka District marks the deadliest structural failure in modern history. The eight-story commercial building collapsed on April 24, 2013, killing 1,135 people. A day before, police had banned access after cracks were found in the structure. However, garment workers were still ordered to return the following day and were caught in the disaster.
