A level rural two-lane highway has a horizontal curve with a deflection angle of 35oand a length of 1,150 feet as it passes through an area where a historical fence is located 26 feet from the centerline of the highway. To provide adequate stopping sight distance, the speed limit along this curve needs to be adjusted due to possible obstructions from the fence. If the lanes of the highway are12 feet wide, determine the speed limit to be posted (operating speed rounded down to a multiple of 5 mph). Assume a perception-reaction time of 1.5 seconds and a friction coefficient of 0.20.
