US 89A in Arizona north of Flagstaff (and AZ389 to Utah border)

I know utah 20 has a couple 9% grades going from 15 to 89...

 

I'd never want to take a truck over 89A.

Poor signing, some steeper grades, abrupt ups and downs and blind turns. Not to mention the switchbacks are seriously tight. It's also quite rough in places, too. Not to mention dawdling motorhomes, gawking tourists, wildlife, and tired travelers.

I drove it once, and wouldn't take it again unless I wanted to go to the north rim, not even in a car.

 

Too late now to help you this time but this is my observation. You ask for advice and they will treat you like grandma's grandmother. Try to get a straight answer from them. Ask them if you will get ticketed for going that way. And if you don't have the nerves of a log truck driver and can't stay between the lines in your lane on the highway then DO NOT TAKE THAT ROUTE!

 

6% and there's only one.

 

like i said, i'm a frequent flyer on that road. and it's NOWHERE near as bad as you make it out to be.

 

since the hill out of page is out of commission. it's going to be the ONLY road to take till who knows when. my understanding is that the hill AND road fell apart.

i'm wondering if that little arizona scale shack will open back up. since the page scale won't be getting used other then local driver license and plates.

 

I take 6% all the time around the country....20 has been the only time i've actually semi freaked out about a grade, so I'm pretty sure there was a 9....

I know you live up there and probably take it a lot, but i'm 90% sure I saw a 9...

 

6 seems to vary state to state though. and i don't see anything to freak out about on that hill. speed limit is only 35. but there ARE a couple of curves that i tend to SLEEP through. LOL.

 

Oh for heaven's sake, there is no problem with either 89A or Utah SR 20. I've run 89A up through Jacob Lake many times with a 53' both directions. And the only time I ever hauled oversize, it was over Utah 20. I used to run it with a 53' all the time too.

Sure those highways are not interstates, but so what. Neither one has curves or grades that any experienced mountain driver should have a problem with.

 

Arizona has a 48' limit on trailers off the STAA routes. 89A isn't an STAA-route. Just because you ran it, or just because an officer on that road doesn't catch you, doesn't mean they CAN'T catch you doing it. Just like US550, US60, etc. If you're with a 53' then you're over length and if they want to get edgy, they can. And with a detour in effect, I'm sure enrichment... ahem, enforcement, will be up.

If you have a 48' or less, no problem. But, with a 53' better to just stick to the roads you're legally allowed to be on. Your motor carrier atlas defines what the state regs are in the front, the STAA regs by state.

Did you know Nebraska allows more than 80k on roads EXCEPT on interstates? Know the state you're running in. If you stick to STAA with a 53' you won't have any problems.
