A horizontal curve on a four-lane (two lane in each direction) highway (11-ft lanes) has PC at station 128 30 and PT at station 134 55. The central angle is 35 degrees, the superelevation is 0.06, and 29.10 ft 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.
