I appreciate the back and forth we have had but it hasn’t settled my opinion.
The one thing I believe to be true is that the blue bridge needs work. The assertion that the bridge needs to be seismically upgraded doesn’t seem based on a concrete legal and economic basis but rather on less-than-expert opinion and anecdotal comparisons. I think you may very well be right in your assumptions of economic liability but I would like to hear from those with more experience and training in that field.
This isn’t meant to diminish your analysis which has been detailed and nuanced but to encourage additional time and resources to answer the fundamental economic questions surrounding the issue.
