I bid jobs for a paving contractor in Oregon. I could give you a ball-park figure about what it would cost if you were building the driveway in Oregon. But you have to know the distance, the width, the average grades--how many feet up or down the road goes from point A to point B--and what the drainage situation is.
               Does it need culverts? Would it have a bar ditch on the uphill side, or would the road be "out-sloped." And is there a place for run-off water to go?
               Maybe I'm a little over sensitive to drainage, being in Oregon.
