This is awful. Reports of at least one fatality, several injuries as a concrete pedestrian bridge crushes several vehicles.

It was just installed and opened on March 10th.

The 950-ton section of the $14.2 million bridge at Southwest Eighth Street and Southwest 109th Avenue was installed Saturday. Workers at the scene told Local 10 News reporter Carlos Suarez that the bridge was undergoing some sort of stress test when it collapsed. Suarez reached out to the construction company for comment, but hasn't heard back.
Miami-Dade Fire Rescue officials confirmed that at least six people were injured. Authorities said one was taken to Kendall Regional Medical Center as a trauma alert.
Eighth Street was closed from 107th Avenue west to Florida's Turnpike after the collapse.
FIU officials previously told reporters that the bridge was being built using Accelerated Bridge Construction methods. The university said the modular construction method reduces potential risks to workers, commuters and pedestrians and minimizes traffic interruptions.

The main part of the 174-foot span was assembled at the side of the road while support towers were built at either end. The 950-ton bridge was meant to connect the City of Sweetwater directly with FIU's Modesto A. Maidique Campus.
I wanted to note that the bridge collapsed onto US 41 (which is 8th St here).

The bridge span was installed on the 10th, it was not open yet. The access to it was not yet completed, and we don't know at this point if the bridge was fully fastened. Initial rumors are a crane cable snapped during a stress test on the bridge, but this is a rumor at this point.
My understanding is that it wasn't open to pedestrians yet, and it occurred during the school's Spring Break.
Saw the note about the stress test, and wondered if that's standard operating procedure while traffic is passing under it?
CNN reports four confirmed fatalities.
The construction company has apparently been cited in the past for shoddy work.

The haste of assembly is somewhat questionable just hearing about how fast the bridge went up. Obviously the structure wasn't complete given it wasn't open to pedestrians but it really calls into question the construction method used. Apparently it only took a week to put the bridge in place over US 41.

That was one of my initial thoughts, that they may have moved too fast &/or taken shortcuts to speed things up.
Don't be too quick to speculate. Accelerated construction methods are very popular now. Just because it went up quick, doesn't mean it's dangerous.

Actually, it only took a day to install the bridge.
However, it took a lot longer to construct the bridge. Just like a modular house, it was built elsewhere and then when ready, it was put into place. This type of construction method is completely normal, and used on roads and bridges and in buildings we all use every day.
Clearly, other design factors are at fault here. The basic technique though is sound.

Didn't Alps link over something about one or two cables stays being installed on bridges board? The fatality count was up to six this morning when I was watching the news.
Edit: Copied the link from Alp's thread:

Definitely looks like something snapped between the end and center modules
What was the point of the giant sunshade thing along the length of it. Looks like completely unneeded weight on there.

Probably for shade for pedestrians, it's hot as balls in Miami most of the year.

Also don't forget the summer thunderstorms. Most colleges and universities in Florida have covered walkways

That's right, it's 64-66 inches of rain a year in Miami if recall correctly?

In the summer, it's generally short but strong showers or storms every day.
