A horizontal curve on a two-lane highway (12 ft lanes) has a PC at station 123+80 and PT as station 129+60. The central angle is 30 degree, the super-elevationis 0.06 and 22 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum sate speed (assuming current design standards) to the nearest 5 mi/h.
