West Yellowstone to I84 in Idaho?

There is - or at least last month there was - major construction on Ashton Hill. Narrow lanes, rough no-pavement areas, etc. It's not a huge issue, but was certainly interesting to tow through! It's possible it's better now, but just a heads-up. Otherwise, 20 is a great road, and very scenic.

Ditto. Check with DOT Idaho. Or you can take the Scenic Mesa Falls Byway that bypasses Ashton Hill. Turn to the East in the town of Ashton.
