Problem #5[10 points]
A sag vertical curve connects a -4% grade to a +4% grade. The curve goes under a pedestrian
bridge at PVI. The vertical clearance under the bridge should be 15ft and the required sight
distance is 984ft. The height of driver's eye is 6ft and the assumed hazardous object is a manhole
without a cover. What should be the length of the curve? Assume S>L.
