The other criteria I used was the suffixes "Way", "Place", or "Alley" -- these are complimentary to main streets with the same name.

I downgraded this to trunk a while back because of all the turnoffs into sideroads -- something a full motorway wouldn't allow.

It's all good, I fixed it a few days ago.

Meaning you reverted a change I made from my own local knowledge.

I spent a lot of time and effort on the new configuration of Route N and Weiss Rd. None of the various aerial imageries are up to date enough to reflect the recent change.

Please make smaller changesets. Preferably less than 50 miles in any direction.

Ok, how about something like MO 79?

Could that apply to high-use arteries like K and Lindbergh?

I'm guessing that even though it's not a divided highway, there's no need to split it up precisely?

Ignore that note about Marcus Theater. That was an old autosaved message from another edit.

Ok, Byrnes Mill is incorporated, all the others are CDPs. I'm not attached to this edit, so whatever you want to do is fine.

Sorry if I reacted harshly.

Everything I listed are CDPs, and all have boundaries on OSM. Usually the tags indicate that they are in fact CDPs and not cities -- that can be updated.

With Defiance, I added the boundary, and the residential area I expanded has nothing to do with the relation. If you'd like to tweak anything, including re-adding the Walnut Spring neighborhood, that's fine.

Should I delete all the other CDP's mapped here?

Spanish Lake
Old Jamestown
Castle Point
Affton
Sappington
Concord
Lemay
Mehlville
Oakville
Murphy
High Ridge
Byrnes Mill
Imperial
Barnhardt
All the other countless CDP's mapped around the country.

If you're up to that task, feel free.

Are you referring to the node being moved or the boundary? I'll move the node back but the source for the CDP's boundary is here: http://www.city-data.com/city/Defiance-Missouri.html

Not opposed to this, if indeed the school did name these routes. Do you have any type of documentation to confirm this? If so, please link.

Yes, it appears to be a driveway.

Just curious, is this from local knowledge?
