Same phrase as the paywall version which caught my eye:

:...inspectors spotted a “significant fracture” in one of
two 900-foot horizontal steel beams. "

900 foot beam? [Non USAians note that's 275 meters!]

Is that a thing? Maybe welded like 'continuous rail'?
otherwise how can a 900 foot beam be made at all?

I'm not an engineer but that doesn't look like a crack to me; it looks like a break. One side is higher than the other.

Cheers

Yup, but CNN and I think others referred to this break repeatedly as a
"crack." What's the engineering equivalent of illiteracy and innumeracy?

Good observation.
Still and all how does one make a 900-ft steel object? Even
ship keels are many pieces.

Here, it might be necessary to dive deep into the engineering
terminology: Does a "beam" in bridge building necessarily have the
proberty of being one continuous piece of metal, or is the bridge
builder's "beam" only restricted to the meaning 'carries the forces of
the road in a certain way', in contrast to a "frame"?

As I never took any Engieering courses, I don't know the answer to this one.

Caveat as I can not seem the images, but yes, you can 'construct' a
'beam' to what ever length you can manage.

Bridges are commonly constructed with supports made from sections of
"box beams" which are constructed from other lengths of 'steel'. Heck,
they even make them out of concrete these days.

Basically the same method, except these days they can build those in
parts and ship them to the final assembly ship yard. Hint, there are some
ewe tube stuff showing 'cut and insert' jobs to lengthen cruise ship.

Something sort of related; to ships.

Easy if it came by sea.
Otherwise, you just join short sections.

Oh, we just love playing spot the howler in movies.

Most people that had half a brain would know that most steel mills take a lot of water and are situated on or near water supplies. They would also know that since that bridge goes over a river that a steel mill situated on a river would move capital beams via barges. It would never even occur to a normal brain that someone would move something like that on a road.
