Alright, I think it's about time for me to make a topic on this.
So one thing that I've noticed about highways in Arkansas is the fact that almost every single numbered highway is split into more than one route. Take AR-74 for example:
I just can't figure out what the reasoning behind why there's multiple highways with the same number here. I don't know if anyone here would know, and I'll probably even ask ARDOT if there's a reasoning for it sometime later.
I believe 74 was once a continuous highway. Over the years, parts of it have been relegated to county road departments. 74 to Devil's Den was
not part of the original 74, but appeared later.
45, another discontinuous highway, was also one route from near Clifty, AR to Hartford (possibly to the OK State Line). Over the years, it has been chopped up, truncated, and realigned. US 62 west of Fayetteville was once part of AR 45, as was AR 59 south of Evansville, and US 271 and AR 253 south of Ft Smith.
