...known by a handful of various names it seems. My Gazetteer called it “Old Highway 8”. GoogleMaps calls it “Lyle White Salmon Road” and “Old Highway” and switching to “Canyon Road” on the eastern end.
A lot of names for such a small road. The views from up top are anything but small though, and the corners are tricky and banked. Highway engineers don’t really seem to like banked curves that much anymore, but this old road still has them where it threads in between a stone formation and a bounder perched atop the edge of the ridge.
