This is what it was to have looked like when complete. The collapsed section spanned from the abutment on the left to the pier to the right. The column for the support cables was yet to be constructed, as well as the second span from the pier to the abutment on the right.

Yeah. They'll probably do it different next time.

Apparently the construction crew was post-tensioning the members for the anchor point nearest the pier (to the left in the video below), which is a perfectly normal operation. Supposedly something broke (not known at present if post-tension member, crane cable or something else) causing a resultant overloading of the structure. You can see in the video the collapse originates in the area where the crew is working.

Video explanation (CAUTION: a little bit of salty language).

Maybe I should have said "their design/construction concept needed more work". I stand by my statement. They should not design a bridge that requires a lot more work while in a "weak state" to complete the project and final strengthening of the span.
-
Maybe the trucks hauling the beams to the job site drove faster than normal because of elogs and stress cracked them, thus elogs caused the bridge to collapse.

What ever construction company that was working on the bridge is toast.

It's the school 's baby and pressure for expediency in construction. Make them 75% liable for all future judgements. And the USDOT (or whoever sponsored and funded this project) and the sub contractor who was on site at the failure can split the other 25%Last edited: Mar 20, 2018

Update:
No crap Sherlock
'Design errors' faulted in Florida bridge that collapsed: agency
Concrete tested was at engineer's spec -
Turns out the upper (central) pylon and "stays" were not structural, but were design elements only.
Quite a bit of progressively bad decision making.
