The bridge began construction under Hyundai Engineering & Construction on April 26, 1995 and was opened to the public on July 3, 1997 by Seoul Mayor Cho Soon (조순; 趙淳).

The original Seongsu Bridge was built by Dong Ah Construction Industrial Company, opening to the public on October 15, 1979.

[3] Fifteen years later, on the morning of October 21, 1994, a span of the Seongsu Bridge collapsed, killing 32 people and injuring 17 others.

[2] The collapse was ruled a result of poor welding, rusted extension hinges, and lack of general maintenance— and would result in the convictions of 16 city government and construction workers on charges of criminal negligence.

[4] In the aftermath of the disaster, the Seoul Metropolitan Government originally planned to repair and reopen the bridge to traffic within three months, but reversed course after public outcry.
