On collapse, members #12 base was knock out by member #11 and pulled down from pylon together with member #11, by north deck fall.Stephen Nuchia (Electrical) said:... I note that the remaining portion of 12 seems to have a "chair" shape, the outside surface extends to somewhere above the location of the drain pipe while the spanward face ends higher, around deck level, and there seems to be a roughly rectilinear transition between the two cleavage planes. ...
