Aren't bridges supposed to withstand the maximum trafic 24/7/365? So tying the collpase to the increased traffic is very far fetched. Or bogus. Trying to blame Nafta superhighway for political reasons.
BTW, I heard that the superhighway is needed to bypass west coast ports where union workers make $120K or more and constantly demand raises. I have a question: how a union differs from racket? Why can't an employer hire workers for less money? Is it free country or what? Why not to outlaw the unions altogether except rare situations when a company employs more than, say, 20% of population of a county.
