Bill is correct. It was totally demolished, re-designed, and constructed as new. |

The presentation I went to concentrated on the failure of the existing sign - I don't recall much being said about the new sign, although I had the "impression" that the entire original sign had been demolished.

I attended a talk by Finley Charney about this sign back in 1998. My notes indicate that a Principal Engineer sealed the drawings but two young engineers with Masters Degrees and with relatively little experience performed the detailed design. A Peer Review had also been done - but the forensic review team found numerous errors in the design and detailing.
Another suggested contributor was the fact that the sign was designed for Exposure Class B (questionable for some quadrants) and a one-third increase was taken for wind. These served to reduce the safety margin against wind, estimated around 60 mph that day.
Form what I remember the top part fell off and removed another 10-20' and that it was redesign at that height and that is what we see today or did thaey add some more height back ??
