This is a three-way talk by three experts about the bridge, which is a practical building but also has an aspect as a work of art.

Mr. Akio Kobayashi: A civil engineering expert in Balibari, who was also a former section manager of the Bridge Structure Special Section of the Tokyo Metropolitan Construction Bureau.
Mr. Vivien Sato: An artist and writer from the Department of Architecture.
Mr. Akira Watanabe: Doctor of Art, who is also the chief curator of the Ota Memorial Museum.

・・It was a fun article just to read, because everyone had interdisciplinary knowledge not only in their specialized fields but also in their specialized fields.

The bridges featured are Ryogokubashi Eitai Bridge Azuma-bashi Bridge Shinohashi Manseibashi Asakusabashi Yanagibashi Nihonbashi Kyobashi Shimbashi. ・・ ・ It can be said that it is almost a bridge tour in Chuo-ku.♪

Regarding each of the bridges listed, there are all changes in the structural form attached, and not only Nishiki-e but also subsequent changes are posted in photographic images, so I feel some science and doboku-like commitment. (^^).

This is a detailed explanation based on nine beautiful old postcards, including historical backgrounds.

The postcards are listed as Tokiwa Bridge Azuma-bashi Bridge Asakusabashi Nihonbashi Gofuku Bridge Kiyosubashi Hijiribashi Sukiyabashi Sendai Bridge. There are a lot of familiar bridges.

The commentary is Mr. Akio Kobayashi, who mentioned earlier.

■People who built the Sumida River Reconstruction Bridge and Modern Tokyo Bridge

You can also look at the photos of the "Reconstruction Bridges", but in the content of "People who made modern Tokyo bridges", a modern bridge was created that allows the bridge itself to be a purpose of appreciation. The background is explained with the achievements of three talented engineers, Masayoshi Kabashima, Toyo Tanaka, and Enzo Ota.

The commentary is Yu Nakai, a professor of civil engineering and urban design at the University of Tokyo.

■Bridge construction method and culture in Edo

Even in the days of Kibashi, Ryogoku Bridge and Nihonbashi, they explained that the design was very "disaster-resistant" and excellent.

The commentary is Mr. Jun Hatano, who has many books related to Edo (architecture).

■Read the designer's intention from the original drawing of the bridge

This is a commentary on Hijiribashi, Yaesubashi, Miharabashi, and Kachidokibashi, which release drawings from the Taisho era to the early Showa era.

In order to be immersed in emotions by looking at the drawings, I think that it is necessary to have the knowledge and experience that will make you feel beautiful just by looking at scores, electronic circuits and formulas ... However, even for amateurs, the design drawings of Kachidokibashi are more reminiscent of ship and airplanes than buildings.

The commentary is Ryuichi Watanabe, an architect who has won various awards for design.

Commentary: Mr. Yoshihisa Ishizaka

Actually, there was a time when I loved reading this book. It is a book called "Going through the Tokyo Waterway", which runs around the rivers and canals of Tokyo on a private motorboat instead of a private car. (right in the figure above)

There is a past that Tokyo's waterways are so attractive that they have just obtained a small ship license with momentum ... (^^)

Such an author explains in detail about "the bridge seen from the surface of the water." The ratio of the bridges that have been featured in Chuo-ku is slightly lower, but you can clearly see "the pleasure of looking up at the bridge from behind".

(Proclaimed) This is a column-like article by Hideo Takayama, an intermediate culvert hunter, but there was something strangely stabbing (^^). Bridges that have already lost their function as bridges and have remained in various forms are called "dark bridges" and are divided into three types.

[Delete] As a monument or specimen, a dark bridge that has been moved from the place where it was built and displayed as a bridge.

[Enclosed] Dark bridges found in culverted green roads and parks

[Nora] The dark bridge that happened to remain on the street corner

I thought that the difference between "enclosure" and "nora" might be subtle (Which is the main pillar of Inaribashi? In Chuo-ku, there are too many fushi (no, bridge) you can imagine, including stuffed bridges (former Shin-ohashi Bridge decorated in Meiji Village, etc.)! (laughs)

------

(From here, it is not related to this magazine, and it is my miscellaneous feeling.)

It seems that "dark bridge" refers to something that has already lost its function as a bridge, but although it has not lost its function as a bridge, there is also a form that "it is not the original form." If you name it without permission,

Desertification Originally, it should have been over the river, but if you notice it, the bridge below was a road (many such as Kuyasu Bridge).

[Reincarnation] Originally, it should have been over a different place, but when I noticed it, a bridge that had a different name in another place (such as the former Ryogoku Bridge that became Minami Takahashi)

The old Dansho Bridge is a rare example of reincarnation on the road. In addition, the present: It is a very rare pattern in which a miniature of the former Dansho Bridge ([Debrid]) is displayed on the Dansho Bridge.
