g A horizontal curve on a two-lane roadway has an intersecting angle of 37o and designated maximum superelevation of 6%. The lane width is 12- ft and the design speed is 55-mph. The radius for the horizontal curve has been set to 3,040 ft and the PI is located at station 150 03.44. Determine whether a transition spiral is needed for this curve (make sure to show step-by-step your process).
