Then, while the stay cable (4C) to be removed is held by the temporary hangers (7), the stay cable (4C) to be removed is detached from a bridge girder (3) and a main tower (2). Subsequently, while the stay cable (4C) to be removed is held by the temporary hangers (7), the stay cable (4C) to be removed is moved together with the temporary hangers (7) to the bridge girder (3) so as to be removed.
