Can anyone give me a list of some steep downgrades and where they are?

I-5 NB & SB at the CA-OR border -- Siskyou summit

Loveland Pass, US 6 in Colorado, especially in winter when they've just finished shooting avalanches up there. There's three parts to the YT clips. I've just linked to Part 2.

I-70 EB just west of Green River, coming down off the San Rafael Swell. I-70 EB down from Vail into Denver. I-70 WB from the Eisenhower tunnel. I saw a JB Hunt go into the truck ramp.

I-17 SB down from Flagstaff to Camp Verde and then right up again from Camp Verde. Saw a guy take the ramp there too.

Yeah, Sandstone and Monteagle too.

US 58 WB out of Tehachapi, CA. First time I did that hill the Jakes went out on a brand-new Freightliner.

I don't recall any steep hills in Florida.

 

The steepest seems to be vail.

 

Say what? I think vail is only 6%. Might be a 7% patch. But Vail isn't that bad, just stinks climbing to 11k feet.

 

If you haven't been west "you ain't seen nothun yet"! Monteagle is a bump in the road. Hitting Wolf Creek, Co. Donner, Pipestone, Mt. and even Cajon outside of LA. Tehatchapi, Ca. Cabbage Pass,Or, and Snoqualmish (sp). Oh yeah, can't forget Parley Summit going into SLC. Don't worry, there are plenty of places to get stupid and dead out there!!

Keep the dirty side down!!

 

I live near it and can't spell it.

 

I84 in PA, NY, and CT, can be fun if heavy. U.S. 44 in CT towards Storrs, OH 7, going to Wintersville with the construction, the whole state of WV.

 

Not that bad? NOT THAT BAD!? I make 3 trips over Vail Pass a night and I agree, it's really not bad at all. When I get stuck in traffic because of an accident my first thought is "FedEx" and I'm right at least 50% of the time. Follow the speed suggestion signs and you'll be okay.

 

I usually think the same thing (and more often then not I am right). But you are right, follow the speed suggestions and you will be fine. I am going down cabbage in a couple of hours. Weather is great, roads are dry and with my weight I get to do a whole 18 MPH! (Yes the speed limit is based on the actual weight of your truck) and I won't complain. I'll start downshifting at the warning signs, turn on the jake and won't touch the brakes all the way down. Hopefully I won't get run over by a FedEx crash machine.

 

I just picked up the East Directory...looks pretty good and accurate for the areas I know in PA.

 

After hitting some of the really beautiful mountainous areas like Vail CO, Truckee CA, and some of the surprisingly steep areas in VA, SC/NC, AL, KY, TX. What I can tell you is that no guide is complete, and even if it were you'd never be able to remember them all. BUT, there will be signs to warn you of Grades. And there will be speed advisories on the worst ones. If you are heavy, trudge down; don't gallop. If you're going to ignore a speed advisory just remember that the overwhelming cause of accidents in the mountains is to much speed. It never hurts to slow down a bit more, but that little bit of speed may be what breaks the horse's back.

Hit those 4 ways and slow'r down hoss.
