Alrighty, that's very informativea, and I appreciate it. But, if I recall correctly (edits to Washington Avenue, Bonanza Road, and Casino Center Boulevard), you told me that state highways don't actually tell people about the road's importance in the network. I could make a list of Nevada State Highways, but the list will (likely) only get smaller as the Nevada DOT relinquishes control of state highways. Where could I make such a page, and how (if possible, like you're implying now) could this list help with road classifications?

Okay. Who even comes up with these rules anyway?

Got it, thanks!

(Late response, but...)
Alrighty then. I don't know if these are signed since street-level imagery is limited here, so I might have to wait a while. From the pictures I was able to obtain from the street leading into the area, the private drives don't appear to be signed, so I could at least change those. This area in particular is a gated community, which could explain the lack of street-level imagery inside the area.

Alright, I see what you're saying now. I've now restored the secondary classification to Hualapai Way. Once again, thanks for sharing this information with me!

Oh, okay then. Thanks for informing me again!

Hello, why did you remove the old alignments of the roads? They're there to prevent users—including myself—from remapping them.

Oh, okay then. In that case, what would happen to Alta? It sees no freeway connection whatsoever despite its connectivity to... a newly-built neighborhood?

Oh, okay. I noticed you did something similar to Buffalo Drive north of some interchanges.

Oh, okay. But wouldn't that be what trunk roads are for, rather than expressways? I'm a bit confused now.

Are you sure Blue Diamond Road is an expressway inside the Valley? Blue Diamond Road has at-grade intersections with many side streets and provides direct access to parking lots. Compare this to Wilbur Clark D.I. Road and Sahara and Flamingo near I-15: They have only one or two at-grade intersections each and provide no direct access to parking lots.

Okay, thanks for informing me! I'll check them out.

Hello, why was Spring Mountain Road under I-15 downgraded to secondary? For that matter, why is this part of Spring Mountain Road primary at all?

Okay, thank you for informing me! I would have never known the difference between those two types of collector/distributor roads, especially when online queries don't help at all. How could I learn such things in the future?
P.S., when I search for the reference code of such a road (i.e., IR15SCD01, which means "Interstate Route 15 Southbound Collector/Distributor Road 1"), all I get are news outlets saying "ramp from Russell Road to Blue Diamond Road is closed due to traffic or an accident," none of which actually explain this category of road. I only know about these classifications thanks to the Nevada DOT's official list/map of state-maintained highways.

Okay. Well, they are classified as collector/distributor roads, which would usually be classed as tertiary roads in the US.

Okay, thanks!

Wait a second. If the 215 were to be tagged as trunk due to its importance rather than its physical characteristics, wouldn't that make Lead Mead Parkway between the 215 and Eastgate Road a trunk road as well? I'm confused; am I overthinking this?

Alright, thanks for informing me!

One more thing: Taking everything you said into account, why is Summerlin Parkway (West of the freeway segment) a trunk road? That's definitely something I did not do; plus, it's exactly like Lake Mead Parkway and Paradise Road: expressways tagged as trunk roads because they're the end of freeways. The only difference here is that this part of Summerlin Parkway/CC 215 is under construction, and since the roads are closed to traffic going to and from Summerlin West, it barely sees any traffic at all. Any and all information helps.

Alright. I'll go ahead and fix these.
