Cause of this Han River bus accident announced by Seoul Metropolitan Government

It is said that the cause is that the route indicator light is not bright enough on a dark night, causing the ship to deviate from the route and become caught in foreign objects in low water.

The area near Jamsil is difficult to navigate due to low water depth and obstacles such as gas pipe protection holes. For this reason, dredging work was carried out last August to secure the water depth in the area near the Gongjamsil dock, which was dredged three months ago to secure the water depth. This means that it is outside this section.

Also, it is presumed that the dry season has arrived early, and since it is necessary to determine how much silt or debris other than the predicted water depth is on the route, only Yeouido-Magok will be operated for the time being.
