Smooth slope road

I have used the drape tool to add a road to my landscape. One of the roads is in a slope so i can’t use the stamp tool. Problem is that the road is follwing the topography to much and is bumpy, and leaning. How do i get my road to look more like reality. I guess the .dwg data is not accurate but is there a way to fix this?
