A horizontal curve on a three-lane highway with 12-ft lanes has a PC located at station 10+00 and PT at station 13+70. The central angle is 25 degrees, the superelevation is 4%, and 40 ft of clearance is available between an obstruction and the centerline. Determine the maximum safe design speed to the nearest 5 mph.
