| March 2012 (38.769 Degrees, 141.507 Degrees) Koizumi Bridge |
The Koizumi Bridge had been retrofit with viscous dampers to absorb energy and protect the superstructure during an earthquake. However, the bolted connections to the girders must have broken when the waves overtopped the bridge. The pit around the pier (in the photo below) suggest that some scouring of the foundations took place at this bridge, perhaps resulting in the loss of the midspan pier.
