The design speed for a two-lane highway (lane width=12 ft.) is 60 mph. The local jurisdiction governs 8% superelevation. The central angel of the curve is 40 degrees. The PI station is at 452+50. What is the curve radius to the travel path (R)? What is the curve radius (R)? What is the curve length (L)? What is the station of PC? What is the station of PT? What is the SSD? How many feet must be cleared from the lane's shoulder edge to provide adequate stopping sight distance?
