Hommachi Bridge, Bridge in Chūō-ku, Japan.

Hommachi Bridge is a steel three-span two-hinged arch bridge on Hommachi-dori over the Higashiyokobori River in Chūō-ku, Osaka. Completed in 1913, it is 46.5 m long and 21.6 m wide, with stone-column ornaments on the piers and balconies above them.

The first bridge here dates from the cutting of the Higashiyokobori canal after 1585, and it was the site of fighting between the Hachisuka and Ban Naoyuki forces during the Osaka winter campaign. Under the Tokugawa shogunate it was a publicly managed bridge; the 1724 Myōchi fire destroyed it along with several others. The present steel bridge replaced a wooden one in 1913.

The bridge gives its name to the surrounding Honmachi Bridge district, created in 1989 from parts of Uchihonmachi Hashizume-cho and southern Bungo-cho. In the Edo period, oil wholesalers gathered at the east end and cotton, kimono and second-hand clothing merchants lined the west end, making this Osaka's busiest area. The bridge is listed among the 50 Famous Bridges of Naniwa.

The bridge carries Hommachi-dori over the Higashiyokobori River; Sakaisuji-Hommachi Station on the Midosuji and Chuo subway lines is the nearest stop. The Hanshin Expressway Route 1 loop has a Hommachi exit beside the eastern end. The deck is open to pedestrians and road traffic, and Higashiyokobori Park runs along the canal bank.

The original design and building techniques from 1913 remain visible in many details of the structure. This early engineering demonstrates how durable and carefully made Japanese bridges were in that era.
