Well, this probably says more about your choice of search terms than
anything else, but it might also reflect just what Google happened to do
when you tested. Rumors say that Google search logic or at least some
essential parameter there is changed daily or several times a day,
mainly to disturb dishonest "search engine optimization".

To deal with the problem of getting so high, I presume.

Probably.

Cool URLs don't change.
You could use HTTP redirects (or could you?), but why _would_ you
a) change the directory structure
b) let such a change affect _URLs_?
URLs are not filenames. If your web server environment does not let you
define the mapping between filenames and URLs as you like, then you have
a very good specific reason not to change the directory structure or
filenames.
