Old (Missouri/State)? (Highway/Route)? 21 is the general form that I can think of.

Legally Union Electric lives on d/b/a Ameren Missouri.

Ameren Missouri is the trade name adopted by Union Electric when it was acquired by Ameren Corporation as part of the merger with CIPSCO, Inc.

It's possibly a candidate for construction in coming years.

I followed this up with a changeset to add access restrictions.

This is the final changeset in a series of changesets I've made specifically to fix up the border of Arnold semantically. It still needs adjustment with the river, but that doesn't impact semantics.

It did not properly take intersection semantics into account, and it did not properly exclude non-roadway areas like islands. It did not properly take sidewalks into account. It was also not edited since its introduction, so I felt it appropriate to remove.

Also Esri Clarity was used here.

Neither StreetSide nor open county records indicate Holzer Drive exists.

I don't know the origin of Holzer Drive in TIGER, but it just...doesn't exist..? There is a driveway with a parallel gated land-access track road here, and the residence to the north has an address on Missouri State Road.

Imagery has not caught up with this yet, so trust me that this is a dirt lot. A bowling alley and a tanning place were torn out. Here's proof of asbestos demolition: https://web.archive.org/web/20230426044600/https://dnrservices.mo.gov/env/apcp/asbestos/demo-details.php?param=11437-2022

By "trace", I meant "align". The ways were already there.

My interpretation of "minor arterial" is strongly highway=secondary, but special circumstances can bump it up to primary or down to tertiary. IMO this is not a special circumstance, though, as Richardson is a commercial corridor that is completely avoidable if your destination isn't along it.

As an Arnold resident I can say we have these street sign anomalies all over the place. AIUI the most "on the ground verifiable" version should be preferred but alternate versions should also be made available for routing et al.

Forgot to cite my source as Bing StreetSide

To clarify: The short trunk stretch was sandwiched between long primary stretches.

This 1.28 mile stretch of North Kingshighway should have the same classification as the rest of the same road. Previously this little stretch was classified trunk even though the speed limit didn't change, its network status didn't change, and it doesn't do anything else functionally. Presumably it was due to this stretch being dual carriageway which is not a valid reason anymore for classifying it as a trunk.

This changeset has a large bounding box due to the relations it touches, but the actual changes are confined to a small area. Sorry for the large bounding box!

This changeset had to touch neighboring Imperial Township, Arnold Township, and the county line.
