Once called "Tomidachobashi" and later "Toibashi," this bridge over the Nishiyoko Canal appears as "Shinanobashi" in records from the Genroku era (1688–1704). At that time, it was described as 13 ken, 1 shaku long (approx. 25.9m) and 2 ken wide (approx. 3.9m). It's said that the Nishiyoko Canal was dug by the first-generation lumber tradesman Nagase Shichiroemon. It flows from the Tosa Canal to the Dotonbori Canal, flowing north to south through the heart of Osaka. Along the shore, there was a great deal of commerce: the canal was lined with porcelain merchants and lumber dealers. As the streetcar network expanded in 1913, Shinanobashi Bridge was replaced by a triple-span (with two piers constructed in the middle) simple steel-plate girder bridge (length: 23.0m; width: 22.0m), but that vanished as well when the Nishiyoko Canal was filled between 1964 and 1971 for the Hanshin Expressway. All that remains now is a stone monument.
