Also good to know is what each talkgroup covers:
26992/Troop-A - Southern Terminus to South of Exit 7A
53264/Troop-C - Exit 7A to Exit 14
27024/Troop-B - North of Exit 14 to Northern Terminus
You'll probably notice that north of Exit 4 you lose the signal of the Troop A system, so the 26992 talkgroup is simulcasted on the Troop C system (as is the 27024 talkgroup).
