Must be nice to have the luxury of taking 12-18 months to evaluate the cause. I wonder if these folks get “paralysis by analysis” or they’re just slow.
I’m no engineer, but if a bridge functioned perfectly well UNTIL some construction began and heavy equipment was parked on it, it’s a good bet the load limit was exceeded. Shouldn’t somebody have approved the architectural/engineering plans for this bridge when it was built? That’s the only other potential smoking gun.
The NTSB is the most thorough investigative unit outside of Scotland Yard. As there are tens of millions of dollars in liability, they are going to make sure the true root cause is known. They have only named two incidents as “unexplained” in their history.
I do agree with you that the heavy equipment and construction seemed to be the only big changes.
