Okay, I guess that makes sense.
Unrelated, but a long time ago, I downgraded Desert Inn Road west of Rainbow Boulevard to secondary. A few days ago, I upgraded Sky Vista Drive to primary because: a) It is the westernmost arterial (for now) of somewhat high importance, similar to how Hollywood Boulevard is the easternmost arterial of the Valley; and (b) it has a freeway connection, making it (IMO) more important than other arterials in the region, like Desert Foothills Drive and Park Drift Trail.
Between these two, I upgraded a small portion of Sunset Road with connection to CC 215 to primary. Are these classifications okay? If not, what's the best way to reclassify them (and Desert Inn Road between Durango Drive and Town Center Drive)?

Retagging Grand Teton Drive and Losee Road to track roads instead of under-construction tertiary roads will leave behind some tertiary stubs at 5th Street and Sandstone Ranch Parkway. What should be done about this?

I know, right?! I would have added all three to name=* if it weren't for the fact that it would cause validation errors and it would be too long of a string. Which of these names should apply to the whole freeway? In other words, which of these three designations would be best fit for name=*?

The official_name=* key is already occupied by the value "Korean War Veterans' Memorial Highway." Adding that would make two names for the highway, which I don't think is possible (or true).

Okay, I guess that makes sense. I was thinking of changing Summerlin to be something like place=community since Wikipedia states that "Summerlin is a master-planned community..." instead of calling it a city or town or something else. Would this tagging scheme gain approval from anyone?

Oh, okay. I guess that makes sense. When I get the chance, I'll fix these road links (and fix the shoulders of the Beltway as well).

On a related note, why is SR 146 (St. Rose Parkway) tagged as highway=trunk? It doesn't link to any cities outside the Las Vegas metro area and isn't a bypass either (IIRC).

Hello, why did you downgrade Summerlin to place=suburb? Summerlin South, which is part of Summerlin (according to the Summerlin website), is outside of the city limits.

Okay. The first part makes sense, but for the second, the wiki says, "roads that can be used by non-motorway drivers should not be tagged with highway=motorway_link." Technically, it is possible to go from Decatur to Valley View and from Rancho, MLK, or Pinto Ln to Charleston or Sahara, all without having to use I-11 or I-15. You did something similar at the Centennial Bowl, where slip roads caught up in the junction were tagged as either highway=primary_link (for Ann Road and Rancho Drive) or highway=secondary_link (for Oso Blanca Road and Sky Pointe Drive). What's the difference between the _link roads in the Centennial Bowl and Spaghetti Bowl junctions? Any info helps here.

Some of these already had a tag of "alt_name= Deputy Bruce Lee [Memorial] Highway".

Adjusted interchange*

Route relations aren't the same thing as turn restriction relations. Continuing forward on Craig Road (onto Fitzgerald Boulevard) leads you straight into the Nellis Air Force Base, which is restricted territory. The "No right turn" relations are for the slip lanes.

Hello, why did you randomly disconnect numerous road and bus routes at the Las Vegas Boulevard and Craig Road intersection? SR 604 and 573 meet at that intersection according to the NDOT's list of state-maintained highways. RTC Routes 113, 603, and 604 also use that intersection, according to the RTC's official website.

Why did you change these roads' classifications to trunk? highway=trunk is used for major, nationwide or statewide routes or bypasses, like SR 160 (which connects Las Vegas to Pahrump) or US 95 (major cross-country highway).

Apparently, it was designated by a law: https://en.wikipedia.org/wiki/Interstate_5_in_Oregon#Route_description

I feel like I would be repeating myself for the 100th time by saying something like, "name = Highway 79 is redundant because there's already ref= SD 79".

Well, I did try to add shoulder=* to some of the ways. Maybe I'll do it once I have more time.

Why did you upgrade this portion of Nimitz Boulevard to trunk? It doesn't connect to any other trunk roads south of I-8.

Okay... Well, how do I tag these, then?

Oh, okay then. (The "splitting" of CA 56 confused me; this seemed to clear things up for me.) I went ahead and added Ted Williams Fwy back to the CA 56 relations and removed Carmel Valley Rd from them.
