A sag vertical curve connects a -1.5 percent grade with a +2.5 percent grade on a rural arterial highway. If the criterion selected for design is the minimum stopping sight distance, and the design speed of the highway is 70 mi/h, compute the elevation of the curve at 100-ft stations if the grades intersect at station (475 +00) at an elevation of 300 ft. Use L = KA to find minimum curve length for this problem.
