Welcome to the jungle ...
... this was life in the late '70's & early '80's in NYC.
Recession, money mis-management, political corruption.
The City of New York asked President Ford & the federal gov't for help bailing them out of a fiscal crisis that was basically a problem they had created themselves promising too many people too many things, prompting the now infamous headline in the 'Daily News':
"Ford to City - Drop Dead".
So, somehow, the budgets were figured out every year. And the city survived the financial gauntlet.
Nobody really bothered to ask how it was that these seemimgly insurmountable budget challenges were miraculously solved.
And in the '80's and '90's we found out.
When entire sections of the infrasturcture had to be closed simultaneously for emergency repairs. The choice of phasing the work to cause mininum disruption was not an option because everything was falling apart all at once. Many bridges had limited to no service. And, going north out of NYC, every single interstate and parkway had construction closures going on for at least two years running, all at the same time.
And why?
Maintenance.
Maintenance is the easiest thing to cut out of a budget on any given year and not have anyone notice. Just dump the problem in somebody else's lap.
So it's obvious to see how "unexpected" tragedies like the recent bridge collapses in North America are possible.
It has nothing to do with technical ability to deal with the problem, only bone-headed politicians dealing with funding the solution.
And you have to remember that building something new is alot more glorious-looking on their personal resume than doing simple "maintenance" work on something old, even when that's all that's required. Plus they can attach their name to the new structure.
If politicians had their way, the Brooklyn Bridge would have been replaced by a much more economically maintainable concrete overpass by now.
Every government, nationally and locally, needs to be held accountable for all of their decisions regarding the maintenance & upgrading of our public infrastructure.
If you don't think so, there's some people down in the city of New Orleans who may beg to differ.
PS - They don't make Roeblings anymore, do they?
