There was a gap in 86. Signage is clearly visible on Bing Streetside indicating 86 occupies the same road as do U.S. 60 and MO 59.

This changeset also added some surface and lanes tags to affected roads which inflated the bounding box

I kept the part of T to the west of 54 as secondary, as it forms a bypass on Old 54.

For some reason, the northern terminus of Z was part of the Z relation but had no tag.

When making road surface gravel, or when adding bridges to gravel roads, make sure to verify the surfaces of bridges

Huh, I don't know why JOSM didn't autocomplete the source field. I used Bing Aerial Imagery and MoDOT's public domain travelway data from MSDIS.

I also moved it north of Chestnut Street because the GNIS import 15yrs ago had it wrongly placed.

I also bumped Route NN to tertiary since it connects to a 2-digit numbered state route and serves as a main street of Parnell.

This is motivated by the idea that you don't need to enter the asphalt road (which Route C follows) in order to, say, make a right turn from Throop Street onto Vanson Street.

I bumped the state route to tertiary out of habit, really, but I don't feel like unclassified is a good fit anyway. If it shouldn't be tertiary, just let me know

Hi, welcome to OSM! Should there be a space in the name between the words "East" and "Throop"? Thanks

I renamed the way from "Trenton Post Office" to "United States Post Office" for consistency with others (that's what it usually says on the building, but Bing StreetSide isn't available here). Feel free to switch it back, though.

I also used Bing StreetSide to locate where on US54 the speed limit changes.

I also added stop signs.

This one also used USGSHydroCached layer for name of Upper Castor River

I also used USGSHydroCached layer for Wolf Creek name

I also switched "State Route H" to "State Highway H". The former is used by MoDOT, and the latter is used by state law. I think the latter is also more acceptable for USPS mail, but idk.

It doesn't matter that it doesn't show up on OSM Carto.

Semicolon delimiters can go in alt_name.

I also added the Hazelgreen Access slipway, but I didn't tag the state park area yet.
