Banpo Bridge Rainbow Fountain is the world’s longest bridge fountain. The fountain is programmed to play different shows during the day and night. During the day, the fountain shows a hundred different configurations meant to evoke waving willow branches and willow leaves. When the sun goes down, 200 lights illuminate the fountain as it sends up dancing, rainbow-colored jets of water in the air in synchronization with music.
WikipediaThe Banpo Bridge is a major bridge in downtown Seoul over the Han River, South Korea, connecting the Seocho and Yongsan districts. The Banpo Bridge is on top of Jamsu Bridge, forming a “double deck” bridge. During periods of high rainfall, the Jamsu Bridge is designed to submerge as the water level of the river rises, as the lower deck lies close to the waterline. This deck incorporates pedestrian and bicycle paths that provide easy access to the Banpo Hangang Park from the north side of the river. Banpo Bridge is a girder bridge and was completed in 1982.
