Design the vertical alignment (i. e., the sag curve followed by a constant grade connection, followed by a crest curve). Assume that we are provided with the elevation of Point I as 34.5 ft. Note, if the calculated curve lengths are too short, please pick reasonable values for them and justify your choices.
