There is video data for the first 2000 feet, or 609.6m, of five passing lanes. Four of the location are at rolling terrain. One location is at slightly mountainous terrain. References to terrain are to the terrain at the areas, not to the profiles of the highways. There are not steep prior grades near the passing lanes. The horizontal alignment is adequate for fast or very fast speeds at all of the locations. The approximate average grades along the first 2000 feet, or 609.6m, of the passing lanes were 0.05 percent, +2.02 percent, +3.15 percent, +4.32 percent and +5.05 percent. There was not much traffic data regarding the location where the grade was 0.05 percent. Passing rates for passing of the first vehicles of groups of three or more vehicles along the first 2000 feet, or 609.6m, of the passing lanes along the steeper grades were typically not more than the passing rates along the less steep grades.
