Grades on US 12 in Washington

[bukhrn]

I've been looking on google maps at US 12 in Washington, we will be heading to Packwood from Yakima, in our 29' Class C with toad, looking at the street view, I can see a grade sign, west of White Pass, but I can't make out the grade, any idea what the grade is & for how long? I assume, (I know I shouldn't do that) that it is a main road in the area, any other problems to look for?

A beautiful drive. Not a lot of traffic on White Pass (US12) as opposed to heavy traffic at certain times on Stevens Pass (US2) and Snoqualmie Pass (I-90). US12: wide shoulders, especially when coming down the west side, and awesome Mt. Rainier photo-opts at/near summit. US-12 and WA20 (North Cascades Hwy - way far north) are my favorite routes over Washington Cascades.

Just did it in the opposite direction. Just a good two lane road with curves and hills that are not extreme. Be sure to fill the tank before leaving town.

Did this route last fall pulling a 30ft. 6500 lb. tt with a Silverado 1500 5.3 V8 with no problems. I thought it was a pleasant drive actually. Don't be intimidated.

I couldn't give you the exact number, but as is typical with these Cascade passes, the climb from the east is more gradual than the drop on the west side. I believe heightwise US12 is lower than US2 (Stevens) but higher than I90. I've only driven it in a car, but it doesn't have a bad reputation.

And what's your alternative? I82 to I90 has a pass, not high, but generally high speed, followed by I90, and a long drive down to the Rainier area. And in the Rainier area, White Pass is the easiest - except for continuing west down the valley of I5. You'll do a lot more climbing in the tow/toad to see the Rainier sights.
