Niigata, Japan's Bridges: Yonahime Bridge on Route 8 (4)

August 2007 (37.3247 Degrees, 138.4513 Degrees) Yonahime Bridge
Another post on the Yonahime Bridge. Note the wind sock at the approach to the bridge. Perhaps drivers are cautioned not to drive across the long span bridge on windy days?
The purpose of today's blog is to show the cross-bracing damage that occurred during the 2007 Kashiwazaki Earthquake. In the photo above we can see that the bridge has racked, putting the cross-bracing into compression, which buckled.
Although not a serious problem, it is indicative of the movement the bridge experienced during the earthquake.
