The bridge is mentioned in the historical text Samguk sagi as having been completed in 760 A.D. (per the Korean calendar). Its original form was estimated to be 60.57 m (198.7 ft) long. Based on analysis of the remains of the bridge, it is believed that there used to be towers at each end of the bridge. The bridge was completed around the same time as the bridge Iljeonggyo (일정교), which is nearby and believed to be similar in design.[1]

Research and excavations on the topic of the bridge were conducted from November 26, 1984 to September 8, 1986. These investigations concluded that there was a wooden bridge at the original site. The first phase of construction work to rebuild the bridge lasted from 2008 to 2013. It resulted in a 66.15 m (217.0 ft) long bridge without the gatehouses. A second phase of construction from April 2016 to April 2018 resulted in the completion of gatehouses.[1]
