Midoribashi Bridge spanned the Sengen River, a canal that once linked the western Hirano River with the old Naka-Koya Kaido highway (located along the present-day municipal boundaries of Higashi-Osaka City). Until construction to fill in the canal began in 1967, the 1,800-meter long Sengen River flowed across the region and was busy with boat traffic going to and from Higashinari and the city center. At the time, there were more than 20 bridges across the canal, and Midoribashi Bridge was one of them. At present, the route of the Sengen River is the Ryokuin Doro pedestrian path, and “Midoribashi” remains as a monument and the name of the intersection on what was once its south end.
