Banpo Bridge: This is Korea's first double-decker bridge. There is a Jamsu Bridge under the Banpo Bridge. The world's longest bridge fountain (Moonlight Rainbow Fountain), it was recognized by the Guinness World Association on December 14, 2008. In order to create the entire width of the river (approximately 700 m), which only the Han River in Seoul has, a water pump for the drop is used in the 1,140 m section of the upper and lower reaches of the Banpo Bridge section, and water is sprayed according to the music. Instead of simply spouting water, the program is structured so that the background music and fountain display harmonize beautifully and harmoniously
