Curb in viewing area

Curb at the north end of the Old Man viewing area where the path meets the parking lot. The path is immediately adjacent to the roadway in the background, and to the parking lot in the foreground. National design guidelines specify a 5-foot separation. The curb separating the path from the parking lot extends above the level of the surrounding pavement on the path side as well as the parking-lot side. Problems: the raised curb directly at the edge of the path and on the outside of a curve will divert bicycle wheels and slam bicyclists down on their side; a motor vehicle which pulls forward until the wheels stop at the curb will extend most of the way across the path. Imagine a bicyclist coming around the blind curve from behind the boulders at the right rear of the photo, a little bit too fast, and facing either of these situations.
