Because yes, Future I-11 has been signed (at those four signs that I added) and designated by the Arizona DOT.

Here: osm.wiki/MUTCD/W#W19:_End_of_Controlled_Access_Highway
The "FREEWAY ENDS" sign is, indeed, yellow.

Okay. I got these instructions from the wiki, specifically the entry for that yellow "FREEWAY ENDS" advisory sign, which says, word for word, "End highway=motorway at this point."

I used Google Maps Street View because I can't think of any other good, updated street-level imagery source. I'll admit that the street view images of that road are about two years old. Also, what's a GIS, and how can I access it for future reference?

Hey. Please don't arbitrarily retag roads like that. There is an at-grade intersection to the east, meaning it's not a motorway. Thank you.

Hello, why did you change the road names and numbers? I used the street signs (on-the-ground rule) for the classification of those roads. There's literally a sign that says "EXPRESSWAY ENDS," so the roadway east of that should not be tagged with highway=motorway.

Hello. Where did you get the name "East North Belt Road" from? According to Google Maps Street View, at the intersection with Tropical Parkway, the street is signed as "Centennial Parkway," and the on-the-ground rule takes precedence.

Alright, I'll keep this in mind. I still find it strange how there's no primary road in Summerlin West, though that might be because it's relatively new.

Well, Galleria Drive intersects Boulder Highway, which is the west–east demarcator for this part of Henderson. Once in a residential neighborhood, Galleria Drive curves from being west–east to north–south. Since Henderson tends not to add directional prefixes to street signs, I could not figure out where Galleria Drive would stop being "West" and start being "South." I hope this info helps.

Hello. Why did you change the name of these roads? I used the on-the-ground rule for the road's names and classifications. Is there something I'm missing? Thank you.

Why did you retag the roads from primary link to tertiary road? They would be better classified as links, mainly because they're only one way.

Hello. Why did you remove the English transactions of the roads? The names are in Spanish. Thank you.

Okay, thanks for informing me!

Okay. (Sorry I didn't respond to this earlier.)

Okay, thanks for informing me. Again, where can I get sources for traffic info? I'll need to check it out before retagging roads again. Thanks once again.

Alright, thanks for informing me. My source for that western boundary was Google Maps, which seemed to make Warm Springs bold at zoomed-out levels until somewhere halfway between Lindell and Decatur. Where could I get sources for traffic numbers? Thanks again.

Okay, thank you for informing me. I won't do it again.

Hello, Joseph R P. Why did you downgrade Warm Springs to a secondary road? It goes all the way through the whole valley and, therefore, should connect to many places. (Examples: Southwestern Las Vegas, the airport, and Henderson.) Thanks.

I've seen JOSM in the edit menu, but it says I need something external, and I'm not sure what it does.

As I said before, I thought it would be better to list cities as areas rather than using points and relations. After I was emailed the consequences of this, I realized that it would make searching for cities harder, so I won't do it again.
