In the olden days, the former Suin Line, a narrow - gauge railway connecting Incheon and Suwon, used to pass across this bridge. It was always crowded with locals and traders who carried sun - dried sea salt and seafood from the Sorae and Namdong areas However, due to traffic and economic development, the narrow - gauge train of 0.762m in width, which had narrow seats, was shut down in 1995. Today, the remaining iron bridge has been restored and is popular with families and lovers as a romantic date course.
