I think that's in Pakistan. Yungas is a little wider (trucks actually pass on it), but probably has had more fatalities due to more traffic. India has some terrifying roads as well.
Not as gnarly but the Sun Road at Glacier National Park, Montana is one road i wouldn't want to lose control on. i was taken back at how high up we were 2-3000 feet in one place without any guard rail.
Some of us were just there this summer.
We rode 89A up to and through Jerome, AZ.
Twas a kewl place and a nice ride!
Not really a scary road, as even Loopy @mexican made it!
You need to name road, Amigo, because I can't make sense of what road you are referring to.
The road that goes UP from Jerome is the "Jerome-Perkinsville Road and it becomes dirt a short way from 89A.
