Niigata, Japan's Bridges: Bridges over the Omigawa (6)

August 2007 (37.343 Degrees, 138.482 Degrees) Omigawa Bridges
A last few photos of the Yoneyama Bridge. This bridge is supported on two tall four-legged towers, two shorter two-legged piers, and seat type abutments. Note in the photo above, the rain from the bridge deck is allowed to pour onto the concrete foundation. The bridge went through an elaborate retrofit after the Kobe Earthquake that is credited with protecting it from serious damage during the 2007 Kashiwazaki Earthquake.
The retrofit included the vertical restrainers (above) that kept the superstructure supported on its steel roller bearings (below).
