The design stopping sight distance of a circular highway segment is 370 feet. The travel lane width is 12 feet and the radius of the highway centerline (R) is 290 feet. There is an obstruction blocking drivers' eyesight. Calculate the minimum required clearance distance (C) between the travel lane edge and the obstruction, as shown in the figure below. (Round UP to the nearest foot and fill in the blank with a number only.) -G.. C sight obstruction R 12 ft
