A few from my locality:
Hatcher Pass East (as seen in its own suggestion thread)
http://www.gmap-pedometer.com/?r=6299125
Real name: Fishhook-Willow Road/Hatcher Pass Road/Gold Cord Road
Length: 9.36 miles
Difficulty: 8/10
Default direction: Uphill/northbound
Reverse access: turnaround at top, come over top of pass on dirt road
With narrow, incredibly bumpy pavement (Alaska can't into good roads), several deceptively tight corners, many cliffsides lacking any sort of guardrail or fence, and runoff area nowhere to be found, this is a road on which you are taking your life in your hands. I haven't had many problems with dirt and gravel getting tracked onto the road surface, but that's a small comfort as you still have to look out of bad hops that could throw a stiffly-suspended car sideways or even off a cliff.
Lazy Mountain

Real name: Clark-Wolverine Road, Wolverine Road
Length: 2.45 miles
Difficulty: 8/10
Default direction: Eastbound
Reverse access: turnaround at end
This is a very short snippet of road, but what a rollercoaster! At the second corner, the road pitches steeply downhill into a gully. From there it crosses a bridge and climbs out the other side, which is the location of the double-apex hairpin thing seen on the map... and boy is that a doozy. The elevation chages are still playing tricks on your mind, and the road may even be banked to the inside (don't remember) to add to the confusion. It is also a very slow corner, and ridiculous amount of dirt and gravel tend to accumulate on the outside edge - enough to get my real-life Sunbird to go sideways at about 35 MPH with just a little braking when coming back the other way (which is downhill on that particular corner). At the end it transitions to some kind of semi-paved surface, then to really nasty dirt - I tried to end it before that point.
