We’re very fortunate that the train which crossed only seconds before the collapse made it across safely. The underlying piers the viaduct is built upon dates back to the mid 19th century. Yesterdays tides were approximately 15 feet high, which is stronger than usual. High tide was at about 1 in the afternoon and lowest tide was shortly after the collapse. These photos show how it appeared before, in October 2008 and just after the incident on 21 August 2009. I wonder if there is a better way of monitoring the erosion under such structures. Underwater cameras? Laser interferometry?
