Not a little grinding couldn't fix.

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...
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.

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,
