MIAMI (CBSMiami) — Florida International University’s massive new pedestrian bridge collapsed Thursday afternoon in West Miami-Dade.
The bridge, located at 109th Ave and 8th Street, collapsed on a number of cars.
There are reports of numerous people injured in the collapse. At least one person was taken as a trauma alert to the hospital, according to Miami-Dade Fire Rescue.
The 950-ton bridge went up on Saturday. It was then lowered into its final position, just west of 109th Avenue that day.
The main span was built next to Southwest 8th Street.
MCM - Munilla Construction Management 1 hr · Our family’s thoughts and prayers go out to everyone affected by this terrible tragedy. The new UniversityCity Bridge, which was under construction, experienced a catastrophic collapse causing injuries and loss of life. MCM is a family business and we are all devastated and doing everything we can to assist. We will conduct a full investigation to determine exactly what went wrong and will cooperate with investigators on scene in every way.

This bridge didn't come close to meeting its' intended purpose...
I’m embarrassed. The USA badly needs infrastructure.
We should be good at it ...
Apparently this section of the pedestrian bridge was installed within the last week or so. The likely cause of this collapse is one of the following:
1. Error(s) in the design.
2. Error(s) in the construction procedures (maybe more likely than a design flaw, with a precast concrete bridge).
3. Materials that didn't meet the design specs.
Of course, this is all based on the assumption that the bridge wasn't struck by an oversized truck or something of that sort.
You were spot on!
Oh, gad. Bill Nelson has found his way to a camera....
“X” is a chromosome. Being male, you got shortchanged and only got one. Women have all the luck.
Couldn’t agree more. That there aren’t cranes there says everything you need to know about that corrupt county.
When they peel this back, this ‘family company’ who won the bid is going to be connected to a pol. I’m more sure of that than I am the sun setting tonight.
Imagine this during a class change with 75 people inside of it. See how it crushed down on itself?
Yep. Crazy. This bridge will be a prime example of total failure in architect/engineering classes for years to come.
Especially since it was designed to be supported by a suspension system. Concrete is great under compression but cannot withstand tension. The cantilevered section could not withstand the tension over it’s length.
No center support either...................
Probably a good call.
Except they can’t call it “infrastructure rebuilding,” can they?
We used to worry about bridges over 50 years old, now we worry about bridges over 50 minutes old. Trump is right, we're falling apart at the seams.
Y?..................
That is probably not rebar, but the ends of post tensioning steel. Prestresed concrete includes steel elements.
He looks like death warmed over. Labeled as an “authority”.
Don’t know if it’s been mentioned yet, but maybe some unnoticeable damage was done when they had to twist the structure 90 degrees to line it up for installation.
