Two solutions:
1. Select more points for the road to make it fit better to the heightfield.
2. Add some base to the road and place it slightly higher. Lots of roads 
have some gravel or such to the left and right, slightly elevating the 
road above the usual ground. Additionally, water running down the hills 
wouldn't necessarily run straight across the road with all the mud, but 
instead, just hit the banking and seep through underneath it.
