Control cities that aren’t reciprocated

[JayhawkCO]

Some New Mexico examples:
I-40 west in Amarillo is signed for Albuquerque. I-40 east in ABQ is signed for Santa Rosa.
I-40 east in Flagstaff is signed for Albuquerque. I-40 west in ABQ is signed for Gallup.
I-10 east in Tucson is signed for El Paso. I-10 in El Paso is signed for Las Cruces.

I'm pretty sure Arizona only has 8 control cities for 2dis in the state- Phoenix, Tucson, Nogales, Flagstaff, San Diego, Los Angeles, Albuquerque, and El Paso.

Also Las Vegas and Salt Lake City.

Dang, forgot about I-15

Easy to do. It's still very strange that Yuma isn't used for I-8.

Las Vegas is also used on I-40 along the US-93 concurrency.

I guess that technically counts, though in that case the control city is really not for I-40, it's for US 93.

You can't prove that.

Yes, I guess you could take I-40 to I-15 to get to Vegas but who would do that?

[Scott5114]

Someone who doesn't want to sit in I-15 traffic on the weekend, probably.

I-15 to I-40 to US-95 is a common enough itinerary that US-95 north has a control city of Las Vegas.

I meant I-40 to I-15 from Arizona. No reason to do that.

Perhaps you should say what you mean.

Another one I don't think I've seen mentioned.

I-84 East in Ontario, OR is signed for Boise. I-84 West in Boise is signed for Nampa.

I-84 East in Ontario, OR is signed for Boise. I-84 West in Boise is signed for Nampa.

Neither Ontario nor Nampa should be signed, should just be Boise and Portland.

And another one in this neck of the woods:
I-84 West in Hermiston, OR is signed for Portland. I-84 East in Portland is signed for The Dalles.

Arizona has a good utilization of control cities.  Only picking the largest cities in the area.  Relatively well known cities in the region.  Good for Arizona!

(More states should follow this example.)

Arizona has to be the only state where I can't think of a single disagreement for what they post. Up in the Northeast all the states are trash. New York might be the best and even they sign Saratoga Springs over Montreal on I-87 north in Albany. New Jersey and Pennsylvania are trash, Massachusetts is ok but butchers I-495 badly.

I still would argue that Yuma would be good for I-8. Metro area is 200k+ and larger than Flagstaff's metro area. No one seems to have a problem with Flag being signed on I-40, and not just being skipped for LA.

[kphoger]

Yeah, I'm surprised to hear Yuma isn't used as a control city in Arizona.  If you remove Phoenix suburbs from the list, then Yuma ends up being the third-largest city in the state.  Plus, it's at the state line and the junction with US-95.

Then again, Yuma only surpassed Flagstaff in population in the 1980s.  In 1970, the city proper hadn't even cracked 30,000 yet.

I feel like as an out of stater Flagstaff is slightly more famous then Yuma due to the Grand Canyon, but I have no clue how famous these cities actually are.

Flagstaff is more famous because of the song Get Your Kicks on Route 66.  But that's not the point.  The point is more that Yuma deserves to be a destination in its own right, more so than Flagstaff.

The main thing Flagstaff has going for it that Yuma doesn't is an Interstate-to-Interstate system interchange—which, in the world of control cities, isn't exactly nothing.

But, at the same time, there's an international border (or close enough) at Yuma as well, and the it's the first one heading westbound on I-8 that's within 15 miles.

And, for the record, California uses Yuma on I-8 eastbound. And also California uses Kingman for I-40 eastbound. Two more candidates for this thread's OP.
