Interstate 11 alignment, though Vegas and points north

[Plutonic Panda]

I refer to state and US road in their respective name, but not interstates. SO YOU REFER TO THE FIVE as I-5? I'll still call CA—99 exactly that. It's just like how when Vincent shot Marvin in the head. He doesn't know why the gun went off. It just went off. Maybe he hit a bump.

Nevada has the same north-south division as California.  Nobody up here refers to "the 80" or "the 580", but as Scott alludes to that's the norm in Vegas.

I wouldn't say it's necessarily the norm, since a lot of transplants hang on to whatever the style was in their hometown. So it's not like nobody says "I-15" (and I think I've even heard a Kansas City-style "95 Highway" a couple of times). But there are a number of things working in favor of the "the" convention—the number of SoCal transplants, the fact that "I-11" has two consecutive vowel sounds which is kind of awkward, and the split nature of I/CC-215 that makes it sort of impossible to refer to the whole thing in any other way. So it's probably at least a plurality using the "the" convention.

I'm from Michigan and the villainous minions of a particular college to the south phrase things with "the" before the name.  It has forever killed my perspective usage of the slang.

That's not just a Kansas City thing.  It's ubiquitous down in the Ozarks.  Official addresses might refer to the road through Bull Creek as "State Highway F", for example, but you'll never hear a local refer to it as anything other than "F Highway".  Likewise, the road from Branson to Forsyth is commonly called "76 Highway".  There might be a limit of two digits (or letters), though, because I've never heard anyone refer to a three-digit route number that way.

Of course, I-80 says hello.

Well, I wouldn't expect them to call the highway "the 11" just yet.

Good lord, the interstate's not in California...It's I-11.

I've got bad news...

Blasphemy. CA can have their "the 405," and Austin, Texas can even have "IH-35," but that is where I draw the line.

Probably after they get everyone to stop calling it "the 95".

That's never going to happen. My lady and my two best friends (all three raised in Vegas) said Vegas people are stubborn. They'll never call the road anything else but the 95.

That is correct. Reno follows NorCal namings for freeways and Vegas follows SoCal namings.
What's a 580? Up in these parts, we call it 395. 🤣

Route 215?  Highway 215?  215 (no other qualifiers)?  Just calling all of it I-215 even though it's not quite right?

I've run into a couple of those. Funnily enough when you ask them if they still call it San Francisco Avenue instead of Sahara Avenue or Bond Road instead of Tropicana Avenue they change the subject.

Vegas is transient enough that in 5 years there will probably have been enough new people moving in and out of the valley that there will be a decent population who has never known it as anything but I-11.

I mean, yeah, you could. But "Route" definitely marks you as a transplant (I don't think that's in common use anywhere west of the Mississippi for anything not numbered 66).

I'm sort of trying to hang onto calling things with their prefixes, but it's hard since my wife is from San Diego and fell straight back into the "the" hole the moment we got the keys to the apartment.
