A horizontal curve is to be designed for a two-lane road in mountainous terrain. The following data are known: Intersection angle: 60 degrees, tangent length = 813.10 ft, station of PI: 2,700 + 10.65, fs = 0.12, e = 0.08. Determine the following. The design speed was found to be 65 mph. a) station of the PC (Enter the first answer exactly, and round the second answer to at least one decimal place.) b) station of the PT (Enter the first answer exactly.) c) deflection angle (in degrees) and chord length (in ft) to the first 100 ft station
