What I find kind of weird is how long it took us to get up to 65 in the city. For a long while, it was stuck at 55, and I think we got the bump up around....2001 or so?
That's correct, and I remember it well, because of a ticket I received in December 2000 at Mile Marker 196(Idaho Road Exit) on US 60. I ended up writing an angry letter to the Governor's Office of Highway Safety pointing out how ridiculous it was to have a modern urban freeway posted at 55, while the older, narrower, non-access controlled segment just east in Gold Canyon (this was before all the stoplights) was much more dangerous and had a speed limit of 65. The speed limits were altered shortly thereafter, so perhaps they listened... or had been planning to do it for a while anyway.
