The longest bridge fountain is located on the Banpo Grand Bridge over the Han River in Seoul (South Korea) which measures 1,140 metres (3,740 ft 1 in). It was constructed by Seoul Metropolitan Infrastructure Headquarters.
Running along the length of the bridge are 380 nozzles that send 54 tonnes (60 tons) of water cascading 43 m (140 ft) horizontally and 20 m (65 ft) down into the river every minute. In the evening, LED lights illuminate the water spray, which “dances” in time to 100 different pieces of music.
