I also fixed a small segment in U that was still residential.

I also bumped it to tertiary.

The overpass was completely unref'd before this changeset.

It also sneaks into neighboring Lafayette County a bit.

I don't know how they created TIGER initially, but my guess is that 3 looks similar to B especially if they were hand-digitizing paper maps or something similar.

I also adjusted some untouched segments with Bing aerial.

I bumped a segment of WW earlier today, and this was a continuation of that.

I did not actually reclassify anything here. That text was left over in my JOSM history.

And I bumped it from unclassified to tertiary.

I know it's been a few years, but TIGER is wrong about the name of this road. It is not called "County Highway Vv". Technically, the road is a supplemental state route (SSR) designated as "VV". Missouri statutes use the format "State Highway *" for state routes, though, so the most canonical name in my opinion is "State Highway VV".

Thanks

Some of these segment had directional prefixes, too, but that's not something MoDOT does afaik.

Sorry, that should read "primary_link" rather than "tertiary_link".

(I would actually be in favor of using tertiary for numbered county roads, too, but that's another topic.)

The highway=unclassified tag is used for roads/routes that are too minor for systematic designation, and they are usually (not required to be) maintained by local government.

SSRs, on the other hand, are designated, signed with letters, and maintained by the state DOT.

No other objects or tags were touched in order to make this a clean revert if needed.

No other objects or tags were touched.

Edit: No it's not.

See changeset/145394324.

In this location, a single-letter (or even a double-letter) supplemental route would not be used for the purpose. If anything, an unsigned spur of 179 would be used.

On June 15, 2023, I added ref and relation for a supposed MO P in Wooldridge apparently based on Bing StreetSide. I can't verify that now, and I do not remember why I added it.

Also, being a designated county road might make it unclassified rather than track? Something for the future
