The Verrazano Narrows Bridge towers prove you wrong...
First - the Wikipedia website is one of Satan's best tools today for altering the true meanings of things as well as recorded history. I would never trust it [blindly] to be telling me the [complete/full/total] truth about anything. I would recommend to anyone to use the highest possible amount of scrutiny when reading anything on that site.
The only thing it is actually good for is to observe the modern view - what people currently think or are being led to believe.
Second - the bridge towers could have sustained error in construction while being built without any 'curvature' calculations.
Show us an affidavit from those who did the construction declaring the use of 'curvature' calculations.
Show us the actual construction plans with clear evidence of 'curvature' calculations.
Third - even if someone were to use 'curvature' calculations on the construction of something, it does not automatically follow that it is 'proof' of any actual 'curvature'.
In this particular example, 1-5/8" is not a make-or-break amount of distance. (Even if true, it will not cause the bridge to fall down.)
Fourth - were the top and base distances actually measured with accuracy? (Or, is it just an assumption based on a calculation?)
This [article/idea/suggestion] has 'multiple fallacy' written all over it...
