A horizontal curve is being designed through mountainous terrain for a two-lane road with
lanes that are 10 ft wide. The central angle is known to be 40, the tangent distance is 520ft
and the stationing of the tangent intersection (PI) is 2600+00.
what is the maximum design speed and superelevation you would recommend?
