A large grain elevator is located 40 feet from the centerline of a two-lane highway (55 mph speed limit, 12-ft lanes and level terrain). The elevator is situated on the inside of a horizontal curve with a radius of 500 feet measured to the centerline of the highway. Assuming that the elevator is the only sight restriction on the curve, what is the available sight distance along the curve (measured to the center of the inside lane)? Does adequate stopping sight distance exist?
