Who Broke The Bridge?

[Jchonline]

The break looks rusted at the seam...probably been that way for at least some time before detection. Lucky.

It was broke for quite a few years if go backwards looking at older posts here. The bridge inspector was fired but it seems the state inspection system in need need of some updates...

Crack was not complete through the box beam. Bottom plate was only 20 percent cracked.
Fired inspector add job of looking entire tie within arms reach. He lied about completing entire length. He deserves to be fired. Video has same cause for crack as my original opinion

I just watched practical engineering video again and that beam sure looked completely broke off in it. Of course it is a high tension member which confuses me how the bridge could stay up, if it was severed*.

They do not show the bottom of the beam in the video. Top and sides were completely cracked.

Photo of the bottom of the beam in the article here. There is a reason why it is described as cracked: The bottom seems mostly intact despite the 1.5" gap and 2.5" displacement at the top.

An Ar-DOT 2019 photo makes it look like the crack started at the bottom edge.

All the best,

A little drywall mud and some paint, no more crack.

Easy peasy, huh. Such cheerful music, blech.

I'll weld that thing right up for a case of beer. Here's my latest work.

Not a little grinding couldn't fix.

Exactly the point of Grady: This was a failure of the Quality Assurance system because it let a single human being make a mistake (or failed to do their job) and the QA system didn't catch it.

Good video by Grady.

It takes awhile to catch that someone is lying about doing their quality control checks

But, it shouldn't. Because you should have a team do the inspection, with a supervisor on the bridge watching the primary person who is inspecting it. Can't just have one dude submit a checklist and trust him implicitly.

Your welding is almost as good as my caulking.

We had to replace a bridge in my area over the last few years.
A popular rumor is that inspectors drilled for concrete core samples and cut thru the rebar.

Just a month ago a major highway bridge was closed due to a similar incident.
Guess that one was caught in time as they re opened a week later.
Heck can't Xray scan for rebar locations?

Heck I once had a metal detection device that actually could locate the wire mesh in my septic tank and that tank was buried 5 ft down,

Our Mud Dauber Wasps do better than that.
