If you're into viatology, there's USFR for United States Federal Route. 

[TheHighwayMan3561]

I thought we had a thread for this sort of thing, but that's probably true of just about everything now.

TH - Trunk Highway (most commonly used in reference to state highways, but is used for all classes of state-maintained routes)
CSAH - County State-Aid Highway (county roads maintained partially with state funding)

SR--State Route/State Road

Except in Virginia, where SR is for secondary routes only (those numbered 600 or higher).

NC too at one time used SR for Secondary Routes.

Also I found it funny that Indiana uses State Road for their state designations considering that is a term used mostly in the southern region.

I've been trying to think of topics for which that isn't true, but it's proving rather challenging. That's one of the reasons the increase in forum activity isn't reflected in thread volume - only in post volume.
