  After watching Seconds from Disaster and Air Crash Investigation for many years, USCSB videos are now my favorite accident investigation documentaries.

  I don't get this. There were large, steadily growing cracks in supporting elements, observed and documented over multiple days. Why on earth wasn't the street closed down? The bridge slowly and visibly announced its impending collapse, which - as I understand it - is exactly what engineers want. The thing nobody wants is a bridge like the Morandi bridge in Genua, where the signs of impending collapse were hidden under thick layers of concrete, until the structure suddenly and unexpectedly gave way.

    Something should have been done about the street, but I sure wish it could have been a sign such as: "WARNING Cracking bridge, proceed at own risk, age 18+ only, do not stop near the bridge." We need a way to have something like that be viable from a legal perspective.
