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 30degree, the super-elevation is 0.06 and 22ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
