tony lee, the Dempster is the road to Inuvik. There are three grader stations along the road, with two graders at each. All six graders are out every day, so we were told and we saw graders all 4 days we were driving on the Dempster.
I remember a little bit of washboard right at the start, for the first 1/4 mile, but then it "smoothed out".
The worst part of the road is actually the paved portion just as you enter Inuvik! Frost heaves and pot holes that would be easy to fix if it were still gravel. The locals laugh at the paved roads, but because it is near the airport, somebody thinks it has to be paved.
