Re: Guano and Bridge Failure

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I missed this one.  It all appears to come to the issue of maintenance.  I wonder if any new technical information on that collapse is available.
A couple years ago, I saw some steel bridges in NYC that were in a very bad - to say the least - structural shape.  Even Verrazzano did not look that good with rust showing through old paint.  I wrote about that on the List trying to get attention of NYC engineers, but did not get any response.
This last May I was in NJ again, and did not find whole lot of changes with the Verrazzano bridge.  Other city bridges - on the way to JFK - looked freshly painted, but I was not able to see if the holes (sic) in the girder webs were properly repaired.
