Osaka Prefecture, Japan's Bridges: Dojima River Bridge

November 2013 (34.6896 Degrees, 135.4849 Degrees) Dojima Ohashi
The Aji River splits into the Dojima and Tosabori at Nakanoshima, an island and the city center.  The Dojima Ohashi is a single span steel through arch bridge that carries Amida ike-suji Road. It was built in 1927 and supported at the abutments on hundreds of timber piles. This bridge was reportedly bombed during WWII although I couldn't see any signs of damage.
This bridge is so close to the water that river taxis and tour boats can't go under it. Therefore a plan to raise the bridge is underway that involves using shallower floor beams and a thinner bridge deck. The resulting smaller depth will provide an additional 1.25 m vertical clearance which is apparently for boats to pass under the bridge.
Looking downstream (in the photo above) from the Dojima Ohashi is the Hanshin Route 3 Kamifunatsu Bridges with utility bridges on either side. Looking upstream (in the photo below) is the two parallel Tamae Steel girder bridges on pier walls.
