A blind horizontal curve has a length equivalent to 54 meters. If the the design sight distance is equivalent to 67 meters, and the middle ordinate is equivalent to 8.2 meters, Calculate the minimum radius of the curve so it can be classified SAFE.

3 Horizontal curves You are asked to design a 5-degree horizontal curve with an intersection angle at the center equals 60°15'. The station of point of curvature is 155 + 26.5 ft. Calculate the following: A. Length of the curve B. Station of the point of tangency (PT) C. For first two whole stations next to PC, calculate the degree of deflection from the PC and chord length from the previous point along the horizontal curve.
