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.

Interesting discussion. I learned something new today!

Interesting. I did not consider the difference between local traffic and other traffic when upgrading these roads to trunk roads. I now wonder if Rainbow Boulevard would be classified as a trunk road or primary road. On the one hand, locals tend to use it more than other primary/secondary roads around the area, such as Buffalo and Jones. On the other hand, Rainbow Boulevard doesn't link Las Vegas to any other cities outside the Valley, if you exclude its freeway links (Summerlin Parkway, US 95/I-11, CC 215/Future I-215). What would be the correct classification for Rainbow Boulevard?

Interesting. I have read somewhere on the wiki that giving motorways their own classification is technically an inconsistency, as expressways are also classified by their physical characteristics. Not to mention that expressways don't appear at all in most renderers (except AmericanaMap.org). Once I'm on PC, I'll fix these.

I think this might have been a mistake, as I don't remember ever adding those tags.

I felt like a transition between motorway, trunk, and primary would make more sense than motorway directly to primary. I would assume these expressway stubs from the end of freeways would receive more traffic than a normal primary road. Is there a specific reason why it would be better to go from motorway to primary than to go from motorway to trunk to primary?

I got the alleys' names from OpenWeb and the Private Drives' names from an accessor's parcel map, also provided by OpenWeb. Just zoom in to the appropriate areas, and they should be there.
