Minor nitpick...US:TX:RM really should have just one member with the rest
in US:TX:FM, Texas is just weird on how they sign that network.

The freeway trailblazers might be useful in this case, since they're white
horizontal rectangles.

Honestly just using the yellow TOLL banner from the MUTCD is probably an
easier goal that communicates the message clearly if toll roads aren't
going to use their own color.

I feel like we should nail down the hierarchy a bit... it's
US:ST:County:City, right?  If not, that makes more sense than just
US:ST:Locale just to cover the edge case potential for two towns with the
same name in the same state (rare, but not unheard of) or a county with the
same name as a city within it that both have their own networks.
