A childs cry for help


Among the survivors of the bridge crash is 10 year old Kaleigh Swift, who was travelling across the bridge on a schoolbus as it gave away. She called her mother and left this message on her voicemail.

  2. My heart goes out to the City and it’s people.

    But Also to the Engineers whose design and stewardship of the bridge is suspect until proved otherwise.

    It is quite possible that the design of the bridge structure itself, and its condition were not at all at fault. The failure looks like situation similar to an earthquake-induced failure, which attacks the earth zone supporting the bridge piers, but apparently there was no earthquake, so suggest look for indicators of deterioration of the earth-to-pier footing environment of the pier at the river edge at the river end of the first section to fall. Perhaps river got you. River action (permeation, scouring, hydraulic pressures, bad mud characteristics, shale permeation) which altered the pier footings environment, or something changed in the underlying strata. Is there porous limestone down there? It would take only a few inches shift in footings system to dislocate the supports of the first span and then the domino effect follows on the rest of the bridge. Could be no fault will be found with the design of the bridge or inspection program. With respect to traffic impact on the bridge, with all the mass of the bridge that the design supports, and how much greater the bridge mass is in comparison to the live loads, hard to think that the live loads caused failure. There have been cases of cross wind taking out a bridge with wind-induced harmonics in the bridge spans, but this bridge has a long history and I haven’t heard anything about weather being a factor.

    God give you strength, and please forgive me if I’m being presumptuous.
