When quality American companies are used, our construction is good.

Yes, this is the kind of news we USED TO ONLY hear coming from Third World Countries.

Design/engineering problem. Prayers for the victims.

Thank you, that was my point. The cure time prior to removal of support, expressed in a number of days, was no doubt included in the specs. It is possible some eager beaver...etc.; that has happened before.

Even a child building a bridge from popsickle sticks would be uncomfortable with the idea of no support underneath or overhead, whether a crane dropped on it or not.

It's a bit more complicated than that. There are different safety factors for dead load (the weight of the structure itself), live loads (the occupants), and environmental loads (wind, snow, earthquakes, etc.). And these safety factors vary for buildings and bridges, too.
Very few applications in civil engineering would use a safety factor of 5. In fact, structures tend to have lower safety factors than many other applications like mechanical systems, aircraft, etc. because the loads tend to be very predictable.

Whoa! I think I’ll only walk across bridges built prior to say, 2000.
Does NOT inspire confidence.

Well, there's your answer.
It was designed as a suspension bridge, but there was no "suspension" going on after they installed that section over the road.
Usually you build the supporting elements (the suspension tower, in this case) FIRST.

Dade County construction inspectors are notoriously corrupt. As is the entire construction industry. Inferior concrete, insufficient rebar, and paid off inspectors. Especially when it is a public funded project.
This will be the case here, mark my words.
To: Romulus
That is probably not rebar, but the ends of post tensioning steel. Ah ... good point.
How ya been, Rom?

The bridge was designed by the engineering firm of Oops & Mybad.
To: Ronald_Magnus
That's not a bad theory.
With precast concrete, the sections are often subject to more rigorous loading during installation than after they're in place.
In this particular case, it looks like it could just be a simple (pathetic, in fact) matter of the bridge having insufficient support without the suspension tower completed. Who the hell thought this was a bright idea?

If you haven’t come across the posts yet, a witness said that something fell from a crane and that caused the collapse. And other reports that the crew was conducting stress tests when it collapsed.
Nothing confirmed yet, AFAIK.
