OK... you can blame me (possibly like W2R's"weeee"?)
We'd canceled our Yellowstone trip a few weeks ago, (we had two long (60 ft) pull-through sites for a week!! those take very early reservations to get!):
-- sibling that we'd planned to be with couldn't go, as they'd lost their house in the Boulder area fire end of last year
-- we also sold our trailer and then the truck
That's probably what did it
As far as repair.... we'd closed out the season a few years ago at Fishing Bridge, which then took much longer to finish than expected. I can't imagine road and bridge work would be anywhere near as easy, as I know that some of the areas washed out have no real alternative routes. I'm reminded of that I-70 corridor just east of Glenwood Springs in CO, and how many years it took to complete.
We'd planned on the Cody side for entry, as that's the easiest to get to Fishing Bridge, but with the damage that also means that there's nothing available north of it (those roads going from the Lake Yellowstone Hotel on the Grand Loop Rd to Tower Junction would all be potentially damaged) and that's a long way to get to the other side if the Norris Canyon Rd can't be used.
As far as the Idaho side- -
we've stayed in Victor before, after the park, as it's a not-to- difficult trip into Jackson (but the road is a 10% grade, with switchbacks and you need the proper equipment (heavy duty, which we had) to pull a load up - - it's closed to truckers part of the year and during really bad weather. There's just no way that you are going to make a commute into the park from there (Tetons are possible, but not the park). ...and I'd also say that Victor itself is very small with few services, including camping sites... hence the trip to Jackson, and the road to Swan Valley (on 26) is not difficult ... otherwise it's a long way out of the way to get to Rexburg.
West Yellowstone has far more availability, with more services... but much more pricey (as would be expected). It's got a lot more sites, a lot more traffic, and delays into the park appear to also be increasing; it used to be the "easy way" as others used the main south entrance, with its noted very long lines, after getting off the plane at Jackson airport.
[edit: in the last trip a few years ago, we also wanted to head up back to Glacier NP... but it had a very big fire that took out a number of campsites (Avalanche, Sperry) and affected others and it was closed. I assume that they might be in operation now... but you need to confirm ]
