Transcription: First, the road is drawn from A to B. Because the level of the road is 120 meters, the cuts and fills begin there. The ratio of the cut is 1 to 1, so the cut lines are drawn 5 meters out from the road for every 5 meters increase in elevation. The ratio of the fill is 1 to 2, so the fill lines are drawn 10 meters out for every 5 meter decrease in elevation.
