I will caution that I know Waze TTS sometimes doesn't handle those perfectly or even guaranteed to be consistent (The "let's take blah blah" initial announcements vs. "turn right on blah blah" for example; sometimes those pronunciations can differ. I have an "A St" which is pronounced as both a long "A" sound and as "uh" depending on where Waze is using it).
"Fire route one ninety nine point one" and "Fire route one ninety nine one see" (no "point") are what I get on a quick test. I'd call that good enough for a Wazer to understand though.
