If you are planning to drive between Eastern Idaho and Jackson Hole (Teton Park) Wyoming, plan on a detour. This may take some time to repair. . . .
There is also a dirt road that goes from Ashton to Flagg Ranch. We did it 30+ years ago in a suburu wagon and didn't think it too bad. Now they recommend High clearance vehicles.

Nope. You'll simply take US 20 directly from IF airport. Easy-peasy. It's possible there will be a skosh more traffic because Teton Pass may or may not have a repair by then, but you'll be fine.We are traveling to Island Park, Idaho, in August. We are flying to Idaho Falls, and driving to Island Park. Is that route going to be impacted? (Dumb question, I know, but we've never been to this area.)
