Olympic Bridge or Grand Olympic Bridge is a bridge over the Han River in Seoul, South Korea. The bridge links the precinct of Guui-dong, Seoul Gwangjin-gu and Pungnap-dong, Seoul Songpa-gu (site of Mongchon Toseong and Pungnap Toseong). The principal boulevard of this bridge is Gangdong Boulevard/Gangdong-daero.
The bridge is commemorated to 24th Summer Olympiad in Seoul. The construction started in 1985, but was not completed until 1990, after the Seoul Olympic Games of 1988, because the bridge under construction had collapsed.
On May 29, 2001, a CH-47D helicopter a.k.a Chinook from ROK Army, attempting to lower a sculpture onto the top of the bridge, crashed and fell into the Han River, killing all three on board. The job was finished later and to this day, the dead are not memorialized in any official form, plaque or otherwise on the bridge.
