Akatsuki Bridge, Road bridge in Minami-ku, Hiroshima, Japan

Akatsuki Bridge is a road bridge over a waterway in Minami-ku, Hiroshima, on Hiroshima City Route Minami 4-ku Line 686. Its deck is 13.5 meters wide; the bridge length is not recorded in the source. Joints in the deck suggest the present bridge was widened by building a new span beside the old one.

A first bridge was built here in 1893 after seven local residents campaigned for a crossing between Ujina Shinkai and Ujina Island. Its double doors, which looked like spectacles when open, earned it the name Megane Bridge. In 1942 the army's Akatsuki Butai removed it to widen the waterway for large transport vehicles and built a new bridge, named Akatsuki after Senda Sadaaki, who had worked on Ujina land reclamation. The bridge survived the 1945 atomic bombing and was later rebuilt.

The bridge takes its name from Chida Sadaaki, the Hiroshima prefectural governor who oversaw the Ujina reclamation that created the land here. The earlier structure was nicknamed "Megane-bashi" (Spectacle Bridge) because its arched reflection in the water resembled a pair of glasses.

The bridge carries Hiroshima city road line Minami 4-ku 686 and is 13.5 m wide. Joints in the deck suggest it was widened by building a new span beside the old one. It stands over the water of Hiroshima Bay in Minami Ward, near the Ujina district and the stone monument at its foot explaining the bridge's origin.

The bridge's name comes from Sadaaki Senda, who led the reclamation of Ujina; the earlier structure was called "Megane Bridge" because its open sluice gates, seen from above, looked like spectacles. A cracked stone monument at the bridge's foot explains the crossing's origin; it once vanished, leaving only its base, before being found and re-erected.
