New Zealand's Bridges: Groynes Footbridge in Christchurch (1)

March 2011 (-43.451 Degrees, 172.606 Degrees)
A steel suspension footbridge with concrete cruciform towers in 'The Groynes,' a meandering wetlands a little south of the Waimakariri River. As can be seen in the photo, the deck twisted due to the shaking during the February Earthquake. 

Every bridge has its characteristic way of responding to earthquakes. Fortunately, the shaking during this earthquake was small enough so we could see the initiation of damage at each bridge. This is better (in many ways) than when there is too much damage, which hides the evidence of how it occurred. 

We'll take another look at this bridge tomorrow.
