At 174 feet with no arching to transfer the load to the end points, I am in no way surprised it collapsed. Even with an arch I would expect a central pylon over that length. A cable-stayed bridge of this size is not "to look pretty". Those cables are an integral part of supporting a span like this. The tower should have been the first element erected, and then cabling attached as the span is moved into place for this type of bridge.

I mean, it's been decades since I've taken Statics, but this much I remember.

I feel like I learned this from Bridge Constructor Portal.

Apparently one of the crane operators was overheard saying that they accidentally dropped a "Big Blue Box" on the bridge, causing the collapse.

Construction Firms Behind Collapsed FIU Bridge Faced Accusations of Unsafe Practices

quote:

The FIU project isn't the first major bridge built by Figg to collapse in recent years. A Figg-assembled span in Virginia fell apart in June 2012 while under construction. Workers were installing a 90-ton concrete portion of the South Norfolk Jordan Bridge when it dropped 40 feet onto railroad tracks below, according to the Virginian-Pilot.

Four workers suffered minor injuries, but state regulators later said it was pure luck that no one was killed.

Has anyone seen a model of what this finished bridge was supposed to look like? Just seeing the proportions of it across the road, I don’t know how anyone could have felt comfortable on that jobsite putting that up and just letting it be.

Looks like just spectacular incompetence at the intersection of design and construction: This was supposed to be a cable stayed bridge.



Usually those are built in short sections starting at the tower and working toward the ends, so each section can be connected up to the cables that support all of its weight.

Here, to minimize the amount of time the road had to be closed, the entire span was built next to the road and then moved into position and supported on the landing structures at the very tips, unsupported at any point in the 200 feet in between.



If it was capable of holding itself up in that configuration, it wouldn't have been designed as a cable bridge in the first place.

The Concord has to use afterburners too. Super cruise just wasn't possible back then.

The Concord fleet spent more time in supercruise than all other aircraft put together.

It turns out that using afterburner to quickly reach cruising speed actually consumed less total fuel than doing it dry.

this is definitely what happened

there's a video going around of the immediate aftermath, and you can see the crane at the collapsed end, hook still swinging

they dropped it a good long ways from the looks of it too
