A two-lane freeway is designed for mountain terrain. G₁ = +3.5%. G₂ = -1.5%. It is determined that the vertical curve length to be 600 ft. The horizontal alignment for the same freeway involves a circular curve, of which PC must happen 50 ft. before the highest point of the vertical curve. Suppose the station of PC is at 100+00. Use a superelevation rate of 4%. Find the station of PVC.
