As the creator of that page, I didn't take living streets into consideration at the time due to how little of these roads there were in the state. They do seem to be on the rise however in more urbanized areas, so I'll add a section regarding them to the draft at some point.

Yeah, I would have taken another quick look at this edit, since the road also wasn't connected to the other ways that it crossed, but I have fixed all that.

Good move. I'm sure there's a way to add proper tagging to the roads themselves to indicate when they are accessible to motor vehicles, but I wouldn't know of it.

Hello, living street in the US is mostly used for roads that are designated to be shared between pedestrians and motor vehicles. If it has not changed since I've been, these roads are publicly open to motor traffic from night to the morning and has a low speed limit for the road to be shared with pedestrians and cyclists. Pedestrian street tagging is used better on a street that is completely blocked to public traffic and only accessible by authorized vehicles, like Merchants Square.

No worries! It can sometimes be helpful to create new trunk routes without prior discussion but removing them- especially if they're ones that were created through a formal proposal- can create contention, but it's not something anyone can get banned over (I'm also not a DWG volunteer). As far as I know the reason you made the change was likely due to trunk tagging only applying to high-speed, high-capacity/controlled-access highways in the past, but it's shifted to refer to primarily non-freeway trans-regional highways that may be as important as Interstates.

Hello, may I ask why this trunk route was removed? This serves as a major corridor linking Billings, Cody, and Riverton.

Hello! Please remember to use the fully-expanded 'Road' and 'Lane' rather than the abbreviated 'Rd' and 'Ln' as this is the format that OpenStreetMap officially uses for road name suffixes.

Hello, just for future reference, be sure to tag footways across roads as unmarked/marked crossings (depending on which it appears as) rather than sidewalks, as well as to connect the pathways that dead-end before connecting to roads to the roads. This allows everything to be properly routable/rendered across different services that use OSM data as well as within OSM itself and avoids close junction errors in the editor.

Hello, I wouldn't call this a "full-fledged freeway" - same for any of the other roads you have edited recently. Several factors can disqualify a road from being tagged as a motorway on OSM. For instance, a road someone would call a freeway or controlled-access in real life may have a small median, low speed, sidewalks, at-grade intersections, or very short length, or may simply be a limited-access highway that coincidentally has two consecutive interchanges.

TN 381 near Johnson City isn't so much a "freeway" to begin with and is rather a short bypass/connector route for trucks/through traffic to have easier access to and from the Interstate and US 11/19W.

The US 221/NC 226 Marion bypass does look like its intention was to have some sort of controlled-access bypass around the town, but it's only accessed by two parclo interchanges where you'd have to make a full stop and a sharp right turn to enter, enough so that you might as well call it an at-grade intersection.

I'm debating whether US 278/Cross Island Parkway on Hilton Head Island makes sense as a motorway considering it doesn't have any factor that would necessarily disqualify from being a freeway, however it simply looks like a limited-access highway that just so happens to have two interchanges along its route.

US 29/South Church Street should've been automatically assumed to not be a freeway considering it has 'street' in its name, as well as that it has a 35 MPH speed limit, a very narrow/low median, and sidewalks. It's more of an elevated/sunken arterial road intended to bypass part of downtown Greenville. Roads like these (low speed roads that appear to be freeways because they are elevated/sunken and access by ramps) are very common throughout the US and are tagged to match the road it's a part of (in this case, it should be primary) with expressway=yes to indicate that it has several qualities that could make it a freeway although a few factors that disqualify it.

Well I'll be damned! I'll clean everything up. Thanks for the notification.

I have reverted the edits that you have made around here. Based on the interactions you've had with other users in Vietnam, it's been made clear to me that the basis for your road edits are projects that you want to exist rather than ones that have actually broken ground. I could not find any proof whatsoever that this was a project poised to happen, let alone one that was already under construction.

As far as I know, parts of it have opened around the southern terminus and within the residential subdivisions to provide access to offshoot roads, and the remainder should be open by the end of this fall. The entire roadway is complete though. I've just added access=no to the sections I'm not 100% sure are open.

Yeah I think you're right. I downgraded these highway sections back to trunk/primary.

place=city has evolved less to refer to places that simply have high populations and more to imply regional importance. Western PA is a very sparsely-populated region compared to the eastern side of the state. Outside of Pittsburgh, New Castle, and some satellite cities of Pittsburgh that are a bit closer to the city than Indiana, there aren't really any other places that would surpass a population of 20k. I think that in a region like this (a mostly-rural area within an otherwise very-urbanized state), I would tag places on the basis that they have at bare minimum 10k population and other factors like how regionally-prominent/notable the place is relative to the region and surrounding settlements. I would use a similar criteria for places in heavily-urbanized areas - if a place has a high population (say, at least 50k pop.) but lacks any sort of centralized commercial area or general regional prominence, then it makes sense to classify that as a town rather than as a city.

I upgraded it to city as it's the highest-populated city in the area. It's common for places tagged as cities to have low populations just as long as they are the most prominent in the region.

Which roads in the changeset are you talking about?

I upgrade roads based on their importance because that's what the highway classification hierarchy is intended for. The road number, especially for state highways like these, is typically meaningless since what road has a number can vary between a short dead-end driveway all the way up to a freeway and can mean nothing more than how the road is funded. These particular roads are part of the Kentucky supplemental route system which is generally minor collector roads like these. Better fit to be classified as tertiary unless it is a major route like Route 1193 which serves as a link between Somerset and Corbin.

These roads in particular here will inevitably be the most important area since they are practically the only major roads in this vicinity, but the "most used routes in the area" criteria should stretch out as far as the county line or even cover this section of the state, or else you'll end up having very minor, narrow, dead-end roads that serve farms be classified higher than they should be simply because they are the most important in that area. Certainly Route 769, which dead-ends at a boat ramp, isn't as important as a road like Main Street in Somerset or Murphy Avenue in Ferguson.

Hello, these roads should not be classified higher than tertiary, as they only serve to connect to scattered rural properties rather than any towns or villages and are not viable routes for passing through to reach other major roads.

Aside from that, I'm wondering as to how the motorway links were changed to tertiary links. The link roads should correspond with the roads (or road of highest classification) that they connect to. The I 275/SR 32 ramps should remain motorway links in this case since they link to motorways rather than tertiary roads. Apologies if I came off as harsh at first, I was surprised to see all the roads in such a localized section be all tagged as primary and to have some of the things I worked on broken, as it does take a while to fix things since reverting edits can create several errors.

Primary highway classification is reserved for major arterial roads or highways that connect other significant population centers. Secondary at highest is what I would classify some of these roads, but a lot of very minor roads like dead-end streets were tagged as primary so I was caught off-guard and confused. It's good to observe the surrounding area to see how everything else is classified or read into what you're working with before changing the classification of roads, as how roads are classified on the map can affect the routing of OSM-based navigation systems or simply be a rendering eyesore.
