An aging overpass in Seoul collapsed at around 2:31 p.m. local time on May 26, 2026, during its demolition process, killing three men and injuring three construction workers [1, 2].
The overpass, built in 1966, was undergoing demolition when a section gave way while senior public works officials and private sector experts were conducting a safety inspection on site [1, 2]. The victims included the chief supervisor of an engineering company, the site manager, and a private-sector expert involved in inspection or supervision [1, 2]. Three other workers sustained injuries in the collapse [1, 2].
Earlier that day, demolition was temporarily suspended after workers noticed part of the structure had slightly sunk, raising safety concerns [2]. Debris from the collapse caused damage to railway tracks and power lines, forcing the suspension or rerouting of over 120 KTX high-speed trains [1].
In response, the Seoul Western District Prosecutors’ Office formed a special investigation team comprising four prosecutors and six investigators to determine the cause and assign responsibility [1]. Authorities are examining possible safety violations and ignored warning signs related to the demolition [1]. Officials from the Seoul Metropolitan Government and the construction company could face criminal charges if found responsible for lapses [1].
The overpass was scheduled for full demolition starting in 2025, with plans to complete reconstruction by 2028 [1]. As investigations continue, the demolition project remains suspended pending safety reviews and legal inquiries.
Seoul prosecutors announced the special investigative team on May 27, the day after the collapse [1]. Authorities are expected to release further findings in the coming weeks.
