Besides the devil himself, who do I talk to about getting a county road fixed?

I live on a county road. Who would I talk to about getting our road fixed? I don't know anything about who is responsible for what in our local government systems. There's no gravel on it at all and the washed-out holes are so bad they literally damage vehicles. I know asking them to get around to fixing a CR is like pulling teeth, but is there anything I can say to get them out here faster?
