A vertical curve crosses a 4-ft diameter pipe at right angles. This pipe is located at station 110+85 and its center, where it crosses the road, is at elevation 1091.60ft. The PVI of the vertical curve is at station 110+00 and elevation 1098.4ft. The vertical curve is 600ft long and connects an initial grade of 1.2% and a final grade of -1.08%. Determine the depth, below the surface of the curve, of the top of the pipe and determine the station of the highest point on the curve. Does the curve in provide sufficient stopping sight distance for a speed of 60mph? Assume a deceleration rate of 11.2ft/sec2.
