"An equal-tangent sag vertical curve connects a –1.5% initial grade and a +1.25% final grade. The design speed is 70 mi/h and the station and elevation of the PVT are 138+70 and 851.5 ft, respectively. A storm drain is to be installed at the low point of the curve. What is the station and elevation of the low point?"
