We have been fortunate in that NY has done extensive work on structural issues before collapse. I can think of some real issues on the 7 line, both on the steel and the concrete that had the potential of causing a disaster if not dealt with. Remember the timber shoring at the turn towards Quuensboro Plaza just before the Thompson Ave Bridge? |
