A vertical curve has an incoming grade of +4.4% and an exit
grade of -2.2%. The length of the curve is 450.00 ft. The
intersection of the grades is at 10+00 and the elevation at that
point is 440.00. Compute the elevation of the +00 points on the
curve. Then determine the location and elevation of the highest
point on the curve. If there is an existing bridge at this location
over the proposed road, and the elevation of its...
