The Seongju Bridge, which was built in 1975 and 1955 respectively, has been undergoing reconstruction since 2016 due to deterioration.

The temporary bridge was constructed using the G.T.B method and is a large-scale structure that reaches a width of 10 meters, a length of 470 meters, and uses 3,796 tons worth of materials.
