The Ted Williams Tunnel, running under the harbor from South Boston to East Boston, was the first part of the Big Dig to get underway. On Dec. 22, 1992, workers lay steel rebar inside the tunnel tube in preparation for the pouring of the concrete floor. Globe Staff Photo / David L. Ryan
Good photo. I'd like to see one of a section JUST before it's poured, though. I think there's probably more steel in place at that point.
Still, looking at this, it's easy to see how they could have installed hangers at this point, or at least hanger anchors. I mean, it would be a regular grid, so it could have been dealt with in the support under the rebar used for pouring.
Amazing that they didn't do this, it seems to me. Bad engineering...no question about it.
