A tragic construction accident occurred on a new bridge in Anseong, South Korea today (25 February), resulting in the death of four individuals and injuring six others.
The incident transpired during the beam installation on an overpass approximately 70km south of Seoul, where five 50m concrete spans collapsed sequentially after being lifted into place by a crane due to the failure of the steel support. The Cheongnyongcheon Bridge is part of the Cheonan-Anseong section of the Seoul-Sejong Expressway toward Pocheon.
CCTV and vehicle dashcam footage reveal the moment of the accident, showing a crane moving along the bridge deck as one side unexpectedly sank, leading to a sequential collapse of the entire structure.
At the time of the incident, 10 workers were performing their duties on-site. Two individuals were inspecting the bridge's installation towards the Sejong direction, while eight others were assisting with the crane operations and scaffolding installation. The workers fell approximately 52m when the bridge deck collapsed.
According to Ko Kyung-man, a firefighter involved in the response, the fatalities included two Chinese nationals among the deceased. Five of the injured individuals are reported to be in serious condition, including one Chinese national.
In response to the incident, the National Fire Agency deployed three helicopters and around 150 personnel to the scene for search and rescue efforts. Additionally, the Ministry of Transport has despatched a team of employees to assist and evaluate the situation on-site.
Experts, including Lee Song-kyu, president of the Korean Safety Experts Association, have suggested the necessity of examining the work sequence employed during the installation process. Lee commented, “Looking at the video from the time of the accident, it seems that an unbalanced load (weight tilting to one side) acted during the installation of the beam,” indicating that it is likely there were procedural errors regarding the installation sequence. He advocated for thorough investigation into the structural design and safety management protocols in place at the time of the accident.
This unfortunate occurrence is part of a broader context of safety challenges within South Korea’s construction industry. According to data from the South Korean Ministry of Labor released in March 2023, there were 598 fatalities among industrial workers in the country, with more than half of these (303) occurring in the construction sector. This figure, while indicating a decrease from the 644 deaths recorded in 2022, still highlights ongoing safety concerns.
Legislative measures were enacted in 2022 aimed at addressing safety regulation violations and holding company management accountable in the event of worker fatalities. Nonetheless, incidents of this nature are not isolated; earlier in February, a fire at a hotel construction site in Busan resulted in six deaths and the evacuation of approximately 100 individuals, including 14 workers who were airlifted to safety from a rooftop. Moreover, a severe fire in June 2022 at a lithium battery manufacturing facility in Hwaseong claimed the lives of 23 workers who were incapacitated by toxic gases.
