On August 8, 2019, the homepage of the online civil engineering museum "Dobo Hirokawa Exhibition Japan River Scenics Twenty Classes-Seggested Country-Like Mountains Similar to Mountains and Rivers" was released.
It's a huge amount of information. If you like rivers and geography, please take a look here.

In this, "River numbering where you can enjoy railway and bridge structures" is introduced. What a surprise, the Sumida River was ranked in the eastern Yokozuna!

There is a commentary on the reasons for selecting each river, and for the Sumida River, "a river where you can appreciate many types of road bridges, such as arch bridges and rose bridges constructed during the reconstruction of the earthquake, in a short section. There are many railway bridges such as the Tobu Isesaki Line of Nakaji Cantilever War Lent Las. "It is said.
Why don't you look at the bridge over the Sumida River again, including the upstream section than Chuo-ku?
