If it is a long road, I would use a single or two bottom plow. To get my 1/4 mile driveway in shape across a pasture, I disced where I wanted the road then used a 3 bottom plow to "throw" the dirt to the middle of the road, effectively pulling a ditch. After that I smoothed it w/ the boxblade, spread my gravel and smoothed some more w/ the boxblade. I still wish I had a pull type blade w/ hydraulic tilt to crown it though. My 10' wheeled boxblade works great but you end up w/ a basically flat suface that doesn't shed water well enough. I can usually get the county to blade it w/ a maintainer a couple times a year then I just handle the touch up.
