Unless it's changed from around 20 years ago, I also found it a pretty hairy route. The road edges are marked either by a cliff face or a cliff drop, and on the drop side only a low concrete kerbstone with breaks in it (to allow rainwater to escape over the cliff).
Not an especially difficult route, but you certainly don't want to overcook it on this road. Course, it may have armco by now (if that's any better). Traffic the more likely problem.
