A height difference of approximately 9cm has been identified at the entrance ramp on the southern end of Seongsudaegyo Bridge in Seoul, leading to a series of reports from citizens passing through the area.
The Seoul Metropolitan Government has determined that this height difference has existed since the initial construction and has remained unchanged for years, posing no safety risks.
According to the Seoul Metropolitan Government on Thursday, July 9, the location where the height difference was found is the ramp section connecting the Olympic Expressway toward Jamsil to Seongsudaegyo Bridge, which is an uphill entrance section constructed with soil and retaining walls.
It is not a road section elevated as a bridge.
The city has recently received complaints regarding the height difference, conducted on-site inspections, and repaired parts such as the guardrail connections in the section.
The Seoul Metropolitan Government stated that the center of the road where vehicles travel is paved with asphalt, causing no disruption to vehicle operation, and that it has been confirmed that there has been no change in the scale of the height difference for several years.
A Seoul city official stated, "We manage the section through regular inspections in the first and second halves of every year, as well as detailed safety inspections every two years," adding, "As there is no sign of progressive settlement of the road since construction, we currently judge that there are no safety concerns."
The city believes it is highly likely that the height difference occurred due to a lack of precision during the process of compacting the soil inside the retaining wall or constructing the retaining wall when the bridge entrance was being built.
However, some have raised concerns, citing the past collapse of Seongsudaegyo Bridge and the recent collapse of the Seosomun Overpass, suggesting that the cause of the height difference needs to be examined thoroughly.
The Seoul city official said, "This is not a situation to worry about collapse risks or structural safety issues," and added, "We will continue to monitor the height difference through regular inspections and manage the area to ensure there are no safety problems."
