The curious case of WY 370

First, a bit of background: Wyoming maintains a set of routes as Service Roads (marked in logs as 80SR, 90SR, 25SR, etc.). These are unsigned and can be gravel.
Now, I pulled up the Sweetwater County GIS (here) just because. This does us the confusing service of marking the service roads as actual highways (It also marks the part of US 30 west of Exit 75 as US 30N... boy is that out of date). Before I zoomed in to WY 28, I noticed WY 370 seemed to have two branches. So I did some digging and found out the part of WY 370 that goes to the airport is actually 370SR, while 370 proper goes down Middle Baxter Road to WY 430. There is no signage as such that I could find, but the logs indicate this change occurred in 2011, and GMSV is only from 2009. To make all of this even more confusing, the airport's address is given as 382 WY 370.

Does anyone have any info on this?

I have nothing to add on this yet, but it is on my list of things to check out in a future visit to Wyoming. Your understanding of the situation matches mine with the sole addition that I think the intent is for the airport road to be transferred to local control (county) at some point. I think the link between I-80 and WYO 430 is the intended final route for WYO 370.
