As a professional civil engineer, I feel compelled to point out something no one else is asking concerning the state Route 16 debacle.
The real question is not about the engineering mistake, or why the state Department of Transportation kept quiet about it. The real question is why the conflicting ramps were constructed.
I would be amazed if the surveyors did not notice the grade conflict before anything was actually built. The contractor was allowed to build according to faulty plans when it must have been plainly apparent early on that there was a serious problem in the design.
