Edobashi is a bridge with a lot of traffic because Showa-dori passes, but how many people can think of the shape? The only point you can see is to look downstream from Nihonbashi, so it may be a bridge that is hard to remember. By the way, if you take a boat and pass under Edobashi, it's a pretty good view. In Edobashi, repainting work is currently underway.
Edobashi is a steel arch bridge with two diameters (that is, one pier in the center of the river), that is, a bridge made of iron. Painting is essential on the surface because iron will rust if left alone, but coating will deteriorate over time, so repainting is necessary to make the bridge last longer. The construction is now underway in Edobashi.
Speaking of repainting of iron, Tokyo Tower is also made of iron. At the Central FM "Doboku Radio", a coating expert told us in "Painting Technology to Protect Tokyo Tower" (broadcast on June 21, 2021). If you are interested in painting iron, please listen to the broadcast sound source.
