Japan's Bridges: JR Natori RIver Bridge in Miyagi Prefecture (1)

June 2011 (38.206 Degrees, 140.883 Degrees) JR Natori River Bridge
A nice thing about Japanese bridge owners and engineers is that they are often adventurous in their choice of bridges. For instance, this railway bridge over the Natori River in Sendai is a five span, 512.2 m long extradosed bridge with a 108.2 m main span. The diagonal elements are prestressed and support the girders in tension, allowing for spans that are a little longer than a girder bridge and a little shorter than an arch bridge.

I think I must have taken this photo from the bullet train on the adjacent bridge. Note the many other bridges crossing the Natori River. Japan seems eager to spend money on their infrastructure.
