It’s not even raining… West Arterial Underground Road locked after 3 months of opening


The ‘West Arterial Underground Road’ connecting Yeongdeungpo-gu and Geumcheon-gu, Seoul, which opened in September, was flooded from the morning of today (30th). The amount of rain that fell in the area was less than 30mm, and we are looking for the exact reason.

This is the entrance to the Western Arterial Underpass.

All lanes are blocked and you will see a notice saying that you are working.

Officials of the operator, the Seo Seoul Urban Expressway, have come out and are controlling the road site.

It was around 7:20 am when the underpass was submerged.

The operator explained that the 400m section of the 10km road was submerged in water due to the rain that started to fall in the morning.

At Seongsan Bridge, we controlled both lanes in a straight direction and mobilized a vehicle to drain water.

Vehicles were not allowed to use the underpass throughout the morning and afternoon.

There was also severe traffic congestion in some sections during the morning rush hour.

An operator of the operator said, “There is a control device that automatically moves the water pump, but there seems to be a problem with this device.”

The Seobu Arterial Underpass is a road connecting Yeongdeungpo-gu and Geumcheon-gu in Seoul, and was opened last September.

The total cost of construction was close to 760 billion won, but the flood damage occurred in just three months.

In particular, less than 30mm of rain fell in Geumcheon-gu and Yangcheon-gu this morning.

Considering that the warranty period for defect repair is three years, the Seoul Metropolitan Government plans to comprehensively check with the operator for design problems and defects.
