One might comment that a fairly large number of bridges, that

Locally, the current hot problem is a historic and well-loved pedestrian
suspension bridge in a park.

One know-it-all claims he talked to one engineer who said "It's reached
the end of its useful life" and offered to design a replacement for
several thousand dollars, which would require many tens of thousands of
dollars to build. Know-it-all wanted the village to hire the guy on the
spot.

When there was skepticism, the know-it-all (a marketing guy, BTW)
brought in another engineer. Know-it-all claims this engineer said "I'd
close it immediately for safety reasons." No details from either of
those engineers on what might possibly fail. In fact, no direct
communication from them at all. All we have is know-it-all's version of
their views.

Meanwhile another registered Professional Engineer examined it and
reported in detail, saying that there is no danger at all, that safety
factors are in the hundreds, that only minor repairs are needed, and
that those can be done by volunteers.

I'm a retired PE, and I agree with that guy. But we'll see which way the
politics go.
