You are designing a highway to AASHTO Guidelines (Height of eye = 3.5 ft and the height of object = 2.0 ft) on rolling terrain where the design speed will be 65 mph. At one section, a +(X4/2) % grade and a -(x3/2)% grade must be connected with an equal tangent vertical curve. Determine the minimum length of the curve that can be designed while meeting SSD requirements. (Hint: 1 mile = 5280 ft). (if X4 OR X3 EQUALS O USE 1)
