So this isn't really about the bad state of our infrastructure (which is really bad, I know), but more about the incompetence of either the engineers who supervised the work or the workers themselves. They are the ones that should have realized the dangers associated with what they were doing.
Yep, vibrations = fundamental frequency/resonance = bridge collapse REGARDLESS of bridge strength/condition. Metro isn't collapsing either wtf is this **** about, a lot of non-engineers commenting on things they don't have a clue about. Not arguing the provinces incompetence/corruption though, contracts need to go to the right people, we pay the most for the least and it's not because we don't have good engineers/construction workers.
