The reverse curve is composed of one compound curve, from point A to C, and one simple curve, from point C to D. Point A is located at the Point of Curvature having Station 12+810.02, point B is located at the Point of Compound Curve, point Cis located at the Point of Reverse Curve, and point D is located at the Point of Tangency. The back tangent of the reverse curve is having an azimuth of 383 degrees and the forward tangent is having an azimuth of 741.1 degrees. The common tangent for the reverse curve has an azimuth of 314.3 degrees from south. It has been found out that the long chord of curve A to C is thrice the value of the chord in curve C to D. The common tangent of the curve A to C is having an azimuth of 251.2 degrees from south and the chord of curve C to D is 174.6m long.
