The Banpo Bridge (Korean: 반포대교; Hanja: 盤浦大橋) is a major bridge in downtown Seoul over the Han River, South Korea, connecting the Seocho and Yongsan districts. The bridge is on top of Jamsu Bridge, forming the upper half of a double-deck bridge; it is the first double deck bridge built in South Korea. 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.
