Original bridge
The original Seongsu Bridge was built by Dong Ah Construction Industrial Company, opening to the public on October 15, 1979.[2][1] The bridge spanned 1,160 meters (3,810 ft) and was 19.4 meters (64 ft) wide, accommodating 4 lanes of traffic.[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.[5]: 175
New bridge
Construction for the new bridge began in March 1996 under Hyundai Engineering & Construction. Construction for the replacement bridge cost 78 billion won (equivalent to ₩134 billion in 2017[6]), about 6.8 times the original price.[7][8] The new bridge was opened to the public on July 3, 1997, by Mayor Cho Soon, and a memorial was held on the bridge.[9][10]
