Reverted, please look at this: https://www.nps.gov/rocr/learn/news/upper-beach-drive-will-remain-closed-to-vehicles-year-round.htm

Thank you for these changes, upgrading these routes to primary make sense to me considering they're part of a shunpike route to avoid the Greenway. I will point out that I did extend the Battlefield Parkway primary route a bit just to connect it to major highways a bit more.

I think this should be reverted, since some parts of Beach Drive are permanently closed to automobile traffic and have been repurposed as a bike trail.

What was the reason for changing an English street name suffix in the US to a Polish one?

I've reverted this and the edit made prior to this one by the user. Apparently, they were copying Google Maps data: changeset/131891902

The presence of two different state route networks- primary state routes (prefixed by 'VA' on OSM, numbered 599 and below) and secondary states route (prefixed by 'SR' on OSM, numbered 600 and above and equivalent to county routes seen in other states)- rarely ever dictate the classification of roads, as primary state routes' classifications can range from freeways like VA 267, the Dulles Toll Road, all the way down to access roads like VA 399 at the Virginia Museum of Science.

Secondary state routes, which account for nearly every other road in Virginia minus those in cities and some counties and privately-maintained areas, are loosely classified in a similar way too, as the majority of them are residential streets, collector roads, or rural farm roads but can often times be major thoroughfares or even expressways like SR 606/607 northwest of Dulles or the aforementioned Belmont Ridge Road, which jumps between tertiary, secondary, and primary in different places.

It would be quite difficult to have a road classification scheme based on highway numbers in Virginia (or anywhere in the US really) for those particular reasons.

Belmont Ridge might still also meet secondary criteria for the meantime due to the roadwork all over the area, but my other reasonings for this change are:
- Northstar Boulevard is being extended down to Stone Ridge to form a single consistent roadway between Lansdowne and Stone Ridge and can even be followed down to Catharpin in Prince William County (making it possible for primary classification in the future), while the Brambleton segment of Belmont Ridge Road will only connect to Arcola.
- Northstar also has commercial developments along its route, whereas Belmont Ridge appears to be intended to serve as a collector road for the residential subdivisions in the area.

Most of these edits you're making look good to me and seem to make sense relative to the universal agreement of what the road classification hierarchy is used for. I would make a quick note for future reference about tertiary roads:

Most roads that lead to a dead end or closely parallel other tertiary roads probably shouldn't be tertiary- however- roads that loop back to themselves or are planned to be extended in the future as well as frontage roads or minor roads that are or are part of an alternative route to nearby major roads might also meet such criteria, but it really comes down to the specific road.

Anyways, I do thank you for helping out with working on some of these roads around here and the input you've given!

I think having both 14th and 15th Streets between K Street and Constitution Avenue primary is fine, as they are both equally-important routes, making it difficult to decide which one should be primary and the other secondary if both are not the same classification, my justifications for each being:

14th Street is the most direct route between US 1 and and 16th Street, making it most useful route for through traffic. It also links to The Mall.

15th Street is the first major through road heading east from 16th Street, and connects to the White House and monuments as well ass Maine Avenue and I-395 Southbound ramps, making it an important route for local traffic.

I would, however, keep 14th Street through Columbia Heights secondary and the street tertiary through 16th Street Heights. 14th Street is a quite important through CH, and through roads like 14th north of the area, which cross paths with many other major roads and/or lead to other major roads at both ends are typically good candidates for tertiary classification.

If I recall correctly, I reverted some of these highways to their previous classifications as a result of a Slack US discussion started by me regarding various functional classification edits to highways throughout Kansas. These particular highways weren't talked about but were just a few of the ones covered by the topic. Most of the highways were reclassified by Stretch Longfellow, however.

The 18th Street Expressway does appear to meet all the requirements to be classified as a motorway, as it's a freeway with a speed limit of 55 MPH, a central barrier, and 5 freeway interchanges before it meets the signalized interchange at I 35.

I've reverted these changes again. If you want to rearrange things, please start a proper discussion regarding them on Slack or the OSM Wiki. Thanks.

Please, do not make major rearrangements to the Washington DC road classification, like I stated in DMs. I've already explained that it is considered rude to undo work that the locals spent a lot of time working on and discussing. OSM is a collaborative project, so it should be less about "I think [x] road should look like this" but more "The locals of the DC region have agreed that [x] road should look like this". I along with many other users in the past have rearranged everything to their current state based on community consensus and input from people.

Please keep in mind, road classification on OSM is not about the amount the amount of lanes, the length of the roads, how much traffic uses the roads, or anything else like that, but rather how the road works and how important it is relative to the roads in the rest of the area.

I cannot find where in the article this is quoted, but for the US trunk criteria, it states:

"As the top non-motorway classification, highway=trunk should be applied in the following cases:
In areas of high population density, to expressways that meet most, but not all, of the requirements for highway=motorway, and provide connectivity between motorways and other trunk roads. These roads should also be tagged expressway=yes.
In areas of medium to low population density, to the most important non-motorway roads that provide principal, long-haul connections between population centers of regional importance.
Historically, trunk in the US has been defined based on physical construction, but the 2021 US highway classification project has moved to a definition based on network importance."

It's also the fastest and most-important route through the city of Miami Beach, connecting I 195 to the MacArthur Causeway, which are also important routes.

Traffic counts should rarely have an affect on the classification on a road because it's not useful for navigational purposes. Trunk classification is for important highways that connect different cities and regions like an Interstate would, and not every expressway or highly-traveled road can be trunk. There is the expressway=* key for high-speed and/or limited-access roads and there are AADT maps to show the traffic counts of roads. Minus motorways, the highway hierarchy on OSM is all about how important the road is relative to the surrounding roads setting aside how many vehicles use it. 25th Street itself is technically more important than the viaduct I'd argue, considering it connects to other secondary roads whereas the viaduct is really only useful for traffic to bypass the surface streets to reach other roads of lesser importance.

Why so? If FL 997 should be trunk, FL 998 should be just as well to form a thorough connection to US 1 without leaving an awkward disconnected trunk route.

It's still a dead-end road though, just like the MIA access road, and for that reason it shouldn't be a trunk road.

In the US, trunk classification is for major inter-regional highways, ring roads, and any other non-freeway road that may be just as important as Interstate highways. The viaduct is a very short expressway that doesn't serve anything other than cargo trucks bypassing the surface roads to get to the airport. Secondary might even be too high of a classification for this road, as per what this road actually is used for and why it exists.

Not sure why I linked a nonexistent Wikipedia article, must be a force of habit. For some odd reason there doesn't appear to be a GNIS entry for this place, but I do know it's a control city for the nearby exit (which was my reason for adding it). Must be an extinct community or very non-notable unincorporated community, which do sometimes lack Wiki articles and GNIS entries. Searching on the internet, some business sites list this as its own community while others describe it as if it's part of Ruther Glen. Perhaps this might be better fit as a place=locality?

Hello, this section of road should not be a motorway as there is an at-grade crossing between the grade separations. I've reverted this bypass back to trunk.
