Roads on ledges

[texaskdog]

What are some of your favorites you've driven on?  Million Dollar Highway one of my favorites.  Trying to think of where other good ones are.

[webny99]

Whiteface Memorial Hwy, Wilmington, NY (note the road snaking down the mountain)
Skyline Drive, Manchester, VT (no Street View, sadly)

Going to the Sun Rd, Glacier NP, MT (haven't been on this one, but hope to someday)

[Max Rockatansky]

Blackrock Road and Kaiser Pass Road in Sierra National Forest come to mind for immediately. 

Those in Pacific Southwest know this is my thing, I'll have a lot more examples when I get opportunity to post.

The Road to Hana on Maui.

[CoreySamson]

Most definitely the Mt Lemmon Highway in Arizona:

CA 180 east of Grant Grove to Cedar Grove.  The Generals Highway from the Foothills Visitor Center to the Giant Forest.  All of Mineral King Road.  Hume Lake Road from Hume Lake to CA 180.  CA 190 on the Tule River watershed.  Balch Park Road/County J37 when it becomes a single lane.  All of CA 155 east of Glennville.  Nine Mile Canyon Road/County J41.  Horseshoe Meadows Road/Old CA 190 and Onion Valley Road/Old CA 180.

Does the Moki Dugway count? (Picture I took in September 2015.)

[paulthemapguy]

^ I was just going to bring up the Moki Dugway!  I had designs on driving it since I was 17, and finally got to do it at 22 (then again at 27).

Other memorable cliffside roads include:

Sections of UT-12 east of Escalante https://goo.gl/maps/wXYMMLCCBqRCDJLRA
Sections of CA-120 west of Yosemite https://goo.gl/maps/wJrMVFci32g5NJVE8
Stevens Canyon Road in Mt. Rainier NP: https://goo.gl/maps/UYK4qoapaQnfGpaf9

Hell's Backbone in Utah one ups UT 12 if you have the means to travel it. 

Old Priest Grade is way more hellacious than New Priest Grade (modern CA 120) west of Yosemite.  Most people think of Lee Vining Canyon and the cliffs descending Tioga Pass when CA 120 comes up. 

Another for Washington that is NPS related is Hurricane Ridge Road in Olympic National Park.

[dkblake]

This is a great list. It's not as dramatic, but I think I-81 between I-78 and I-80, which literally follows the top of a Pennsylvania ridge, is pretty neat.

Skyline Parkway, Duluth: https://www.google.com/maps/@46.7742291,-92.1246332,3a,75y,89.59h,90.73t/data=!3m6!1e1!3m4!1slORp6TzfoXmYSHlwE86AmA!2e0!7i13312!8i6656

The dirt part of AZ 88 east to Tortilla Flat.

Catalina Highway above Tucson.

I always thought that CA-89 on top of the ridgeline between Emerald Bay and Cascade Lake was rather fun and interesting to drive on:

It's a long way down either way with no shoulders or guardrails...

I use it as my cover photo on Gribblenation's Golden State Highways page:

Related to CA 89 there is a couple other noteworthy ledge segments:

-  Implied CA 89 on Lassen Park Highway mostly follows the south flank of Lassen Peak from the cliff-face. 

-  CA 89 descending Monitor Pass is mostly upon a ledge.

Blue Ridge Parkway

Skyline Drive

(although perhaps more "ridge" than "ledge", except for the pull-offs)

[Max Rockatansky]

Historic Columbia River Highway in Oregon.

[CtrlAltDel]

Would something like this count?



(I-278 and other roads in New York City)

[Max Rockatansky]

The Old Ridge Route (Old US 99) and much of CA 18 (Rim of the World Highway).

There's some quite busy ones in So Cal.

CA 74 west of Lake Elsinore
CA 74 again south of Palm Desert (best known for the opening scene of It's a Mad Mad Mad Mad World)
San Diego County Road S22 west of Borrega Springs
CA 243 entering Idyllwild
I've driven all these. Most of the bigger climbs into the mountains - Idyllwild, Big Bear, and the San Gabriel Mountains - have a few scary cliffs on one side of the road at some point. And that doesn't even count driving to Big Sur on CA 1.
