Hwy 22 west out of Jackson to W. Yellowstone
We will be moving in a couple of days from Jackson, WY to W. Yellowstone, MT. My mileage guide says it is approx the same mileage going up thru the Grand Tetons + Yellowstone as it is taking Hwy 22/2...

We take our dually up and down that pass minus the 40' fiver. Since I'm the head mechanic on this machine, we use it hard but I wont abuse it. We see some rigs from time to time with overheating situations going up and stinking brakes coming down. Don't know what you have but if a diesel you better have an exhaust brake. And with info that Cloud Driver gave about the re-route in Yellowstone, the directions he gave are excellent. If the pass is the only way that is one thing but there are two options. Also you really don't have to go back into Idaho Falls, you can take off 26 at Ririe and cross over to Rexburg with is on US 20 to West Yellowstone. It will save a couple of miles. We use it if doing what you want to do.
