Moreover, a railway bridge over the Tama River (the Rokugo River), which had been planned to be made of imported iron and stone from England in the beginning, was made of wood due to a budget cut (later it was replaced by an iron bridge in 1877 due to its rapid deterioration).
また多摩川（六郷川）の橋梁も、当初はイギリスから鉄と石材を輸入して架けることにしていたが、予算削減のため木橋に変更されている（後、1877年に老朽化が早いため鉄橋に交換する）。
