Problem 3 A sag vertical curve connects a -1.5% grade with a +2.5% grade. The PVI is located at station 475 + 00 and has an elevation of 300.00 feet. The design speed is 70 MPH. Compute the elevation of the curve at the even 100-foot stations between the PVC and the PVT and find the station and the elevation of the lowest point on the curve. (2 Points)
