Those are the AHTD districts for highway dept offices. As he mentioned in his original post, there are 6 districts for the Highway Police districts.
To clarify:
Arkansas
Highway Police is a division of the Arkansas Highway and Transportation Department and monitors commercial traffic (but can stop general traffic, too). The districts are different than what the AHTD uses. The AHTD has 9 districts. AHP has 6 (as I understand it).
The Arkansas
State Police has a patrol division that is divided up into Troops that patrols Arkansas highways (general traffic but can stop commercial, too). They also have a CID division that is divided up into Companies and covers different areas than the Troops. There are also some other divisions of ASP but let's not get into those.
This comes up every now and then and seems to always cause confusion - I've seen people argue over and over that this isn't the case but it is. They are completely separate with their own talkgroups on the AWIN radio system, their own dispatchers, offices, etc.
I've searched before, fairly extensively, and not found a map showing A
HP Districts. Plenty for A
SP Troops, and sometimes mistakenly named online, but I haven't found a true AHP map. If someone has one then hopefully it'll get posted sometime.
Hope this clears up some of the confusion but it may not as, quite frankly, it is pretty confusing in and of itself to try and explain it...
