Steepest grade you ever pulled or went down.....

Highway 20 in BC East of Hagensborg there's a stretch of 6 Km of 18% with about 15 km of constant 8%-14%. They improved it, used to be you would have to pull a set of B-Trains down 1 at a time because of the switchbacks.

 

Dave you talking bout Salt River Canyon in Arizona...Yeah that a good 8% i think with some switchbacks and a couple of tite curves...

 

I don't remember for sure... might not even be US60. It was up above and east of Phoenix where the mine was.

Just looked at a map. Was 60 and I guess that was the Salt River....

 

All my yrs driving were true over the road all 48. I used to always leave the big road avoiding scales n loved flying under the radar. I never stressed over weather condition, however, 1 day I said I'll take 147 in colorado w a load of acid at 79000 lbs during January. I don't think it was the steppest but defiantly one of the memOrable. I think it took me 4.5 to go 160 miles. I realized I made a mistake after I didn't anyone after 2 hrs n only passed a total of 5 vehicles. Do anyone else know about 147?

 

I had a friend who went out to Colorado (in a 4 wheeler) and took 147 for part of the drive...and she found it scary. Since this particular friend is normally very much the thrill seeker and was only driving a 4-wheeler, I guess it's enough said about 147 if SHE found it frightening.

I remember being a teenager and having to get off the interstate one memorable time in North Carolina because traffic was backed up and I needed to get my friend home. We ended up on this 2-lane highway with steep grades, no street lights...oh, and did I mention--about several thousand deer that insisted on standing by the road and at least 20 who decided to bolt in front of the car? Funny thing about it was that I was one of only three vehicles to get off on that particular exit, too...and the other two vehicles turned off on local streets

 

It is either 18% or 20% when you turn off of rt 118 to go up to Red Rock past Rickets Glen state park on rt 487 in PA. Was on a jobsite on top the hill hauling loaded up and empty down one winter. Good times.

 

As many other's have said, mine was a State Hwy in PA, 13% I believe... combine that with a 43K load, that was a blast...

Back when I was freshly solo, made the same mistake too once.

Went down a backroad in WV that (with the Full Jake and in 2nd gear), if I didn't have the brake pressed hard, gravity would take my RPMs from 1K to 2.5K in a second...

"4H Camp Rd" in Morgantown, WV, will never forget it... Most challenging road I've ever driven. Gotta swing out and take up the whole time, no guardrails and a deep ravine right at the edge.
A 1.5 lane, twisty, steep road that Had to be done in 2nd all the way... At a couple points, my trailer bumper actually scraped the hill I just went down...

 

driving tow truck, I used to always go to the South 180th street hill in Tukwila Washington just south of the mall. Always seemed that trucks would try to go up the hill and wipe out the clutch, or driveline.

So I would take my 30,000 plus tow truck up there and hook up to them on the hill and then get first gear and crawl up the hill and shift on the semi flat spots.. I think by time I hit the top of the hill I might have been in 3rd and doing about 15 mph...

 

Steep enough to know the importance of finding the right gear.

 

On US60 that I posted about, it was told to me by a guy at the mine that it would save me time. It may have saved miles but took a year or so off my life!

Hard to believe at very close to 80,000# that I made it unscathed!
