Six vehicles collided inside the Nogo-san 1 Tunnel on the Seoul Metropolitan Area 1st Ring Expressway in Yangju-si, Gyeonggi-do, on Friday [1].
The incident caused significant traffic disruptions and required a large-scale emergency response to extinguish flames within the confined space of the tunnel. Such accidents in tunnel environments pose high risks due to limited egress and the potential for rapid smoke accumulation.
The pile-up occurred around 11:40 a.m. [1]. The collision triggered a fire that engulfed two vehicles: a sedan and the SUV positioned directly ahead of it [1]. A third vehicle, located behind the others, was approximately half burned [1].
Emergency responders, including police and firefighters, arrived at the scene to manage the blaze and direct traffic. Despite the severity of the fire and the number of vehicles involved, officials said that no one was injured [1].
Witnesses described a sudden halt in traffic as emergency vehicles flooded the area. "The cars were not moving at all and I wondered what happened, then I saw many fire trucks and ambulances had arrived," an unnamed witness said [2].
Authorities closed lanes to facilitate the firefighting efforts and the removal of the damaged vehicles. The closure led to a temporary traffic jam for commuters using the expressway. The Nogo-san 1 Tunnel is a critical link in the regional transport network, and any blockage typically results in widespread delays across the Gyeonggi-do area [1].
Investigation into the exact cause of the initial collision is ongoing to determine if driver error or road conditions contributed to the six-car chain reaction [1].
“No one was injured”
This incident highlights the inherent volatility of tunnel accidents, where a simple collision can quickly escalate into a hazardous fire. Because tunnels restrict ventilation and access for emergency services, the lack of casualties in this six-vehicle pile-up suggests effective emergency response timing and potentially the successful operation of tunnel safety systems.
