OH: why does US127TrkCin go the way it does?

[neroute2]

There currently don't seem to be any signs in the area of ColAve_N, where US27TrkCin splits. Historically, the whole thing was a large one-way circle on Dooley-Elmore-Colerain, so the way we have it was southbound only (northbound used Dooley to Elmore). Given the utter lack of signage in the current configuration, I see two logical ways to map it:
1. Keep it as it would have been pre-reconfiguration, with a single US27Trk_N point either in the middle of the circle or on (then as now two-way) Dooley halfway between Colerain and Elmore
2. Use the shortest route, which is the old northbound route, splitting the two truck routes at WilDooByp

There was a US 27 cutout up until at least 2012 here - https://maps.app.goo.gl/8nyzkDHLGoFdH8b3A - before they deposted nearly everything in this area.

A 2016 article about the reconfiguration has zero mention of the truck routes - https://www.cincinnati-oh.gov/manager/capital-acceleration-plan-cap/news/avenue-and-elmore-street-near-spring-grove-avenue-in-northside-now-two-way/

There is also apparently a VERY poorly signed US 52 Truck.  Hopple St has explicit shield back to at least 2007 - https://maps.app.goo.gl/4MTNE6Mj6cE1AThb9 - and I-75 SB to Hopple where US 52 gets off 75 has a LGS that says Truck Route.

Also curious is that there are a couple US 42 ALT shields on the TRUCK route near the south end...

Honestly I am not sure. Signage is pretty bad. I reached out to Cincy traffic engineering and asked for clarification. I'll see what I can find out about 52 and 42 as well (I found one ALT 42 sign plus a TO 42 sign).
