“who are sufficiently trained that they can be brought in to inspect “
Uh huh. Brought in by who? Or are they just out “walking the earth” and looking to right the crack-challenged structures of the earth?
EVERY bridge in the Midwest, whether a big Interstate job like that one (and there are several) or a country culvert was examined for signs of bed and footing erosion, visible cracks, rust, corrosion, etc.
ALL OF THEM.
They had everybody who worked for the federal government who had the slightest ability in any matters regarding or affecting bridges out looking. Same with the state and local governments.
Sorry you missed it all! Lots of fun I've heard.
