A sag vertical curve joins a -6% grade and +5% grades. If the PVI of the grades is at Station 355+50 and at an elevation of 156 ft., determine the station and elevation of the PVC, PVT, and the low point for a design speed of 60 mph. Sketch the curve and label the PVI, PVC, PVT and the low point with their stations and elevations. Note: You should check the stopping sight distance criterion and riding comfort design criteria, using the one that controls. 2.
