As a longtime Missouri resident, I am almost a southerner, and I just want to say that i don't believe anybody ever named a road for a copperhead.

Do we name roads for skunks, mosquitoes or poison ivy? No, we don't. And whether we are northern or southern, we don't name them for poisonous snakes, either.

The Missouri Department of Conservation says that nobody has ever died of a copperhead bite in Missouri. Of course they are to be avoided nonetheless.
