The beauty of the design behind the bridge
● Bridges are designed with priority on functions (strength, durability, etc.) to ensure the safety of people and cars crossing over them. However, when small fishing boats, boats, water buses, etc. sail underneath the bridge, the back (downside) will be exposed to the eyes of the passengers.
● It's a backside design that can't be seen by people crossing the bridge, but there you can see a well-developed functional beauty.
This artificial beauty, how is it reflected in the eyes of the fish in the river?
● This time, I focused on the backside of a total of nine bridges on the Sumida River flowing through Chuo-ku. Depending on the time and purpose of the bridge, you can see that the design on the back side also differs greatly.
※At present, many bridges, such as Kiyosu Bridge, Eitai Bridge, and Kachidokibashi, are being painted by the Tokyo Metropolitan Construction Bureau to increase longevity, making it difficult to see the appearance of the bridge.

（４） Sumida River Ohashi
（５） Eitai Bridge
（６） Chuo-ohashi Bridge

● Since there is no sidewalk under Tsukiji Ohashi, which opened last November, Hashimoto's design could not be confirmed in detail. .
※If you want to go under the bridge of the Sumida River mentioned this time, including Tsukiji Ohashi, we recommend sightseeing by boat.
