Seoul City plans to restore the old waterways of the upper reaches of the Cheonggyecheon stream into an eco-stream. While the covered parts of the stream are being removed for restoration, the author aimed to develop plans to restore the old bridge placed thereon. As a basic study for the restoration of the Shingyo bridge that existed on the Baegundoncheon stream, which is being restored, this study aimed to explore where to place the bridge and how to restore it. This is based on the investigation and estimation of the original shape of the Shingyo bridge, with the purpose of identifying the most appropriate restoration plans through literary reviews and field surveys. Based on the findings from the investigation and estimation of the original shape of the Shingyo bridge, it is thought that the bridge was built between the end of the 18th century, when the Hanyang Doseongdo was made, and the 1840s, when the Suseonjeondo was made. Given the results of the map and photography analyses, the Shingyo bridge was presumably located in the center-left of Shingyodong Intersection of today. Six parapet stones of the Shingyo bridge remain at present, which are stored in the Cheongwoon Elementary School in Cheongwoon-dong, Jongno-gu. Identified in the photos, the Shingyo bridge was structured with six prop stones and ten parapet stones on six stone pillars. In deciding where and how to restore it, it would be the most appropriate decision to place the restored Shingyo bridge on its presumed original location. However, this is not feasible given the current situation. Hence, the author considered historical and cultural aspects and developed reasonable criteria, under which the new location was chosen, which is 100 m southwards from the presumed original location of the bridge on a roadside with a safety zone and wide pedestrian paths. Two alternatives to placing the bridge on the Baegundongcheon stream were considered, i.e., east-west and north-south directions: the author suggests that the restored bridge be placed in the east-west direction, giving priority to the restoration of the waterways of the Baegundongcheon stream and the original direction of the Shingyo bridge.
