“Of the five great metropolitan bridges it was Shinohashi that remained in its original wooden state the longest. How I miss the days when all five of them – Umayabashi, Azumabashi, Ryogokubashi, Shinohashi, and Eitaibashi – were old-style, Edo-style wooden bridges. When I think, as a further example, that there are said to be hardly any old-style covered boats left in Tokyo nowadays, I realise just how much the city has changed.”

Shin-o-hashi [new great bridge] was first erected in 1673 downriver from the Ryogokubashi and rebuilt of wood numerous times — mostly recently in 1885 (the image above). In 1911, the wooden Shinohashi would be replaced by a modern iron truss span (below). In 1910, only five bridges spanned the Sumida River (there are now 14). Shinohashi was the last of the great wooden spans built during the feudal Tokugawa Era that crossed the waterway dividing Tokyo’s Low City [Shitamachi] of workers’ housing and shops from the High City, Yamate [mountain hand], of daimyo estates and Edo Castle.
“Shin Ohashi, ‘New Great Bridge,’ built on the site Hiroshige’s Ohashi in 1911. was the last Meiji bridge, the strongest and the most technically advacned, using, like late Meiji buildings, Carnegie steel.
“It had the usual three-span Pratt trusses but unlike the others had a steel-plated roadway instead of a wooden deck. Decoratively, too, it outshone the others.
“To the basic bridge a pedimented portal topped with airy scrollwork and globes made of steel ribbons had been added. Electric scones projected from the portal posts. Curving granite obalustrades illuminated by lights mounted on granite obelisks led to the walkways on either side of the bridge. And the steel railings displayed the sinuous curves and circles of a new Western style just now entering Japan – Art Nouveau.
“… The splendid Shin Ohashi did not succumb to the  quake and was not replaced until 1974 when it was moved to Meiji Village [Nagoya], which found space across a pond for one span, roughly one-eighth of its original 173 meters. ‘Carnegie’ can still be read on the members.”
