A 5˚ curve (measured at the centerline of the inside lane) is being designed for a highway with a design speed of 65 mi/h. The curve is on a 2% upgrade, and driver reaction time may be taken as 2.5 seconds. What is the closest any roadside object may be placed to the centerline of the inside lane of the roadway while maintaining adequate stopping sight distance?
