New Zealand's Bridges: Chaney's Overpass in Christchurch (2)

March 2011 (-43.430 Degrees, 172.646 Degrees) Chaney's Overpass

Another look at Chaney's Overpass. There are cracks, holes, and ejected material on the ground from February's earthquake. My friend Kawashima-san (in the yellow vest) is so well-known in Japan that he brings his own film crew on earthquake investigations to record his thoughts. 

The bridge barrier rail is bolted to the underside of the deck overhang. I wonder how effective it is at deflecting vehicles? They painted the bottom half of the pier walls for some reason. Maybe it makes them less reflective to oncoming traffic at night? The barrier rails are pretty close to the pier walls. I wonder if they have rules on how close the piers can be to traffic? 

It looks like the slope paving on the far embankment has slid downward. Also, it appears that the wingwall goes straight out instead of running parallel to the roadway.
