No worries, thank you for response and reverts. Happy mapping!

Hello, please do not downgrade trunk roads to primary based whether or not it is access controlled or how many lanes it has. The definition of a trunk route in the US has shifted from controlled-access or high speed roads to simply major highways that connect significant towns and cities as well as other important highways like these. If a road is controlled access, the expressway=yes tag can be added to it to indicate so.

A Reddit post isn't a sufficient enough source for verifying something like this. Do you know of an FDOT document or news article confirming the construction in this section? I was in this location back in October - after you made these edits - and do not recall noticing any sign of construction here.

Hello, it looks like you created a duplicate node for Centralia. One previously existed here: node/158546647

Dammit, thanks for letting me know. I'll fix it.

Normally I catch myself just before I add objects to the super relation, but the one time it was a big edit I slip up.

I tagged Page as a city for the reasons that it is the largest city in northern Arizona away from the I 40 corridor (aside from Tuba City, which isn't really a city) and that it also serves as a major hub for all of the national parks/forests and other nature reserves and recreation areas in the region, as well as a major highway junction in general.

I'm well aware that trunk routes can just "dead end", like CO 82 to Aspen or US 1 to Key West, considering they have nowhere else to go, but in many cases the dead-end trunk routes simply exist just because they are expressways, like the ones around Tucson. NM 264 didn't exactly connect to the Arizona border so I assumed it was just a leftover of trunk = expressway tagging but that as I went over wasn't the sole reason I extended it. I also do recognize that not every place tagged as place=city can or should be connected to each other by trunk routes directly, like Carson City and Ely or Winnemucca and Klamath Falls because the roads linking them have even far less traffic or population along them than the ones criss-crossing the Navajo Nation. Places like Tuba City and Window Rock aren't exactly trunk route connection points on their own, let alone worthy of place=city, but they do add to the importance of the route between them, because they're relatively significant in their respective regions and serve as major junctions and commercial centers for the local areas.

The NM class. page appears to still only be in the draft/proposal stage according to the banner at the top, and I don't assume those have yet been completed or are set in stone so I take them with a grain of salt. If this is outdated then I can remove that tag and put in the reasoning for making NM 90 trunk (which is to link Silver City to Tucson and places in that general direction).

AZ 264 is the most direct connections between the population centers of Gallup and Page plus further areas like St. George and Albuquerque. Functional Classification maps aren't very relevant to how roads should be classified on OSM because they vary by state which often leads to over/under-classifying roads. Same can kind of go for AADT stats, which can be more useful in urban areas to decide which arterial are the most important to drivers, but out in the middle of nowhere, roads will always have traffic counts significantly lower than those of sections that serve to adjacent towns such Window Rock and Gallup, which is as busy as it is because travel between two closer towns is significantly higher than travel between two distant ones.

As for consensus, I didn't start a discussion for reclassifying this highway because I figured I didn't need to start one. It's only extending an existing trunk route to connect with others, so I considered that the intention of it should've been clear. I've never really understood why time should be spent on starting a discussion thread on a subject relatively minor to something like undoing edits that were the result of a prior discussion or mass edits like reclassifying a bunch of roads or imports. It seems easier to me to just make an edit and quickly revert it if it were to be unanimously objected or contradicts specific statewide guideline regarding it or simply discuss it on the changeset if only one person objects.

Hello, while I do think VA 122 should be upgraded from secondary, it's still a quite lightly-traveled route and doesn't serve much trans-regional traffic between larger population centers. Bedford and Buena Vista are also relatively small towns, so tagging the highway as primary instead might be best.

Hello, I don't think 7th/9th Streets should be trunk since it is fully-bypassed by I 264 and I 65, which link the downtown area to the outside highways. This route's best fit as a primary road.

Hello, Corridor Q shouldn't be a trunk road yet as it is currently disconnected from other trunk roads and it will be a while before the extension past Elkhorn City and the one to Grundy open up. Major highways, especially primary and trunk highways, should be classified based on the other highways that they connect to in the present day rather than what they eventually will connect to in time. This is unless the trunk route along the current alignment of US 460 is rerouted via VA 83/SR 744/Corridor Q/KY 80, which the OSM routers suggests to be more direct than staying on 460.

That was my assumption actually, since I've seen roads like these used this way all over the place in various cities and small towns I've been in around the country. I believed tertiary was sufficient enough for a local street that serves as a de facto bypass of a traffic light, since compared to Bridge Street (which serves as 'main street' for businesses and connects the rest of the town to them) it's just a minor downtown collector road.

For Longmont, the criteria was that it has a population of 100k+ which is the point where places of this population are best tagged as cities in most circumstances. As for the rest, these are all the highest populated/most prominent cities within their respective pockets of the state. I made this edit as a result of a discussion on the OSM US Slack.

A road number shouldn't really dictate how a road is classified unless it's something like a US Route or Interstate (but even those are debatable in some cases). Virginia is a great example of this as there are some secondary/unsigned highways tagged as trunk because they serve to connect other major highways or cities, such as Parham Road, Nimmo Parkway, and Liberia Avenue and vice versa with primary state highways being simple driveways to state buildings.

As for the road itself, regardless of its route designation, it makes sense to have Liberia as a trunk road because it's what you need to use if you're coming from somewhere along or north of the 28 corridor down to SE PWC or vice versa, and it provides a direct connection between two major trunk routes. I myself have used it for getting from Harrisburg, PA or Frederick, MD down to where I live.

Hello, I have reverted this changeset. I live in Leesylvania just between Woodbridge and Dumfries. Both 234 and 294 are just direct as each other if you're coming from the area I live around and take basically the exact same amount of time to use. Aside from that, the two routes serve different purposes:

234 connects Manassas and areas towards Front Royal down to Dumfries and areas towards Fredericksburg, whereas 294 serves to connect Manassas and areas towards Centreville down to Woodbridge and areas towards Alexandria.

Regarding Liberia, this serves as a bypass of Manassas to connect VA 28 to VA 234/I 95.

I have talked to you about reclassifying trunk roads in Virginia, specifically NoVa, stating that they are complete for the time being. Unless any new roads that would meet trunk criteria are built (or any existing roads are upgraded or realigned to a standard that would make them qualify as a major trans-regional route) or if a current trunk road is removed or downgraded to where it's not useful for long-distance traffic, there shouldn't be any more trunk road changes in the area. Same might apply to primary too.

There might still be some roads that could be upgraded to/downgraded from trunk or primary out in other parts of the state, but road classification in Northern Virginia for the most part is complete.

I wouldn't really make a judgement on highways on OSM based on what the state considers them to be because how highways are classified by state is inconsistent with other states. Some maps have 2-lane controlled access roads shown as freeways while some show roads like Corridor Q as not. The allowance of bicycles or any low-speed vehicles to travel in the shoulders also shouldn't indicate the classification of road (unless there is something like a pair of bike lanes along it that frequently cross ramps) since what's allowed on freeways also varies by state, especially since some states let bikes in Interstates. It all comes down to whether the road is a controlled-access, high-speed, and divided highway. Corridor Q may not meet Interstate standards or even freeway standards in most if not all states, but it serves as such and doesn't really feature anything that many freeways don't have as many other freeways around the country have minor driveways or even sections to make U-turn.

Hello, I upgraded the road to motorway because it is a controlled-access road, with the only at-grade intersections being some track/service roads for maintenance/construction vehicles plus a RIRO with what looks to be a house at the end of the road. It's quite common for some freeways (including Interstates) to have very minor at-grade intersections with median breaks to provide access to maintenance lots or properties that were not removed or grade separated from the ROW when the roadway was built, and for some non-Interstate freeways to have RIROs with minor public roads. I think that if there were more houses with driveways directly connecting to the highway or if the intersections with median breaks were roads that led to other roads or more properties, then it wouldn't be a controlled-access road and shouldn't be a motorway.

Hello, I'm not sure when exactly it was rerouted (maybe within the past year?), but it can be confirmed that it follows this new route here: https://www.virginiaroads.org/datasets/VDOT::lrs-route-master/explore?location=37.287111%2C-82.284677%2C14.28

Hello, welcome to OpenStreetMap! Please be careful when you modify objects, as you either intentionally or accidentally removed place=city from Columbia node, which removed the city's placemark from the map.

Not sure why this edit was made but I have reverted it. Custis Memorial Parkway is exclusively a 55 mph 4-lane toll road.
