Osong Underpass Interior Photos Released... Mudflat-Level Ground Where Feet Sink Deeply

Partial Release of Accident Site at Underpass
Muddy Floor... Drainage Work Obstacle

A large volume of water suddenly poured in, submerging 15 vehicles in the Gungpyeong2 underpass in Osong-eup, Cheongju, Chungbuk. Part of the site was revealed to the media on the 17th. This is the first time the search site has been disclosed since the accident occurred.

According to Yonhap News, rescue authorities opened about 10 meters from the tunnel entrance to the media. It is reported that the interior of the underpass has been exposed as much of the water has drained.

The road surface is filled with mud. It is said that the mud is deep enough to cover up to the ankle. As the muddy water pooled on the road drained away, only mud is presumed to remain.

Meanwhile, there are still sections inside the underpass where water has accumulated. It is reported that some areas have water deep enough to reach the necks of rescue workers conducting foot searches.

Currently, rescue authorities are carrying out drainage work to enter the underpass. The fire department is using a 'high-capacity water jet system' that pumps out 30,000 liters (ℓ) of water per minute to remove the water. However, the mud accumulated in the underpass is reportedly hindering the drainage work.

Additionally, toxic gases are being emitted from the stagnant water, which is considered a safety hazard for workers, so air circulation work is also underway.

Meanwhile, the underpass was flooded in an instant on the morning of the 15th at around 8:40 a.m. when the nearby Miho River embankment burst, allowing river water to flow in and submerge 15 vehicles including city buses.

Immediately after the accident, nine people were rescued at the scene. The cumulative death toll is 10.

The fire department plans to complete the rescue and search operations for missing persons who have not yet been confirmed after removing the mud and water.
