Yes, but using opening_hours without giving any times as a way of
fiddling free-form text into a tag would be abusing it, in my opinion.
Especially if there are other ways of doing it.

Indeed. I had to look through the examples for conditions to convince
that free-form text was allowed. If it had been just one example I'd have
worried that it had slipped in by mistake, but there are enough of them
to convince me that whoever put them there believed free-form text
was allowed and that nobody objected to those examples.

If the bridge were usable at certain specified hours then open_hours would
probably be better. But there is no fixed time when it is passable.

Usually they are closed during a rainy season. This bridge isn't always
in the dry season. Also, engineering work on the damn could mean the level
is low at some other time of year. From the description in Wikipedia, it
doesn't feel seasonal to me.
