All investigators took charge of investigation of historical modern bridges located in each parts of Japan divided into 9 areas : Hokkaido, Touhoku, Chubu, Kinki, Shikoku, and Kyusyuu. They investigated records and documents on the historical bridges and conducted field investigation. The investigated bridges were restricted to bridges constructed from the Meiji era before World War II.Data such as photos of current appearance, dimensions, technical and designing characteristics were recorded according to a format. In areas where a lot of bridge data were available, the bridge data were analyzed from various points of view. A lot of data could be collected, especially on truss and arch bridges, although data on suspension bridges is hardly available because of replacement.The fact that the girder system was mainly adpted in many girder bridges shows that designers of those days had no confidence in bride foundations. it is interesting to note that most arch bridges are Rhose bridges, and that tied arch system was adopted in many steel arch bridges.

所有调查人员负责调查位于日本各地的历史现代桥梁，分为9个地区：北海道，东北，中部，近畿，四国和九州。他们调查了历史桥梁的记录和文献，并进行了实地调查。调查的桥梁仅限于第二次世界大战前明治时代建造的桥梁。根据格式记录了当前外观、尺寸、技术和设计特征等数据。在有大量桥梁数据的地区，从不同的角度分析桥梁数据。虽然悬索桥的数据由于更换而很难获得，但可以收集到大量的数据，特别是关于桁架和拱桥的数据。许多梁桥主要采用梁系统的事实表明，当时的设计师对桥梁基础没有信心。值得注意是，大多数拱桥是拱桥，许多钢拱桥采用系杆拱系统。
