I noticed that your road was set "down in" a bit. With water the old saying is "It's not the volume but the velocity" that causes the erosion. Water bars run at an angle to the center line of the road. We typically make them about 120° off the center line (90° + 30°). Too steep of an angle 135*° + will speed the flow and cause the water to start the erosion you are trying to defeat. You want to slowly remove the water from the road. The water bars them selves want to be more of a large "speed bump" size, not a ditch per say. Since your road is set in you will either have to bring in fill to raise the surface up or run the water bar well off to the side, cutting into the side bank. I would not dig a ditch parallel with the centerline of the road to remove water, you will end up with a lot of erosion that you are experiencing now.
