Tucson Freeways

[Roadwarriors79]

One thing I will never understand is how come the Tucson area, which is very anti-freeway, gets state route numbers like 210 and 410, while the Phoenix area seems to have a lot of random numbers for current and future freeways?

As far as the signage goes, if/when ADOT replaces all the Clearview signs on I-10 and I-19 (and maybe SR 210), it will look better and be more consistent.

Since they can't designate them Interstates 210 and 410, this might be the next best thing.

"Can't" or "won't?"  ADOT (or its predecessor) had already used I-410 and I-510 in Phoenix in the '60s, and had assigned I-710 to that infamous never-built freeway in Tucson in the '70s.  I thought that for whatever reasons, they just prefer to not use 3DIs anymore.
