Looks like some pretty steep and tall slopes on that cut and fill work.
Given the other mud flows in the area, there must have been a lot of rain and snow melt saturating the ground.

Yea, that's going to take awhile to repair ;-)

eh, just toss a Bailey bridge across the gap!
The Casey Jones video does mention the problems Jackson and many of it's workers will have. So many of the employees of the Jackson tourism/adventure/hospitality industries use this road to get to work.
I'm no expert on geotechnical engineering. But I am astounded that the Wyoming Department of transport thought they could reopen this road in a few days and that they already had works begun.
On a slope as steep as this it doesn't take a genius to see that this is a big problem.

How dare the dirt return to the original contour of the land.
In comments on other reports is the observation that Jackson Hole is too expensive for the workers who support the very wealthy.
The big places have dormitories on-site. Many live in essentially group homes, like you get to share bedrooms, or have a place behind the sofa. Otherwise it's a commute.
Fortunately the Feds are going to get involved to repair it.
Here's a map of one route:

I have travelled that pass too many times to count. Went to school in Idaho and used to go to Jackson Hole to ski on weekends.
Late fall 1972, I did a spin in my 1968 VW beetle on that road near the top of the pass where it is sheer cliff up one side and down on the other. Luckily, I stayed on the road when spinning as there were no guardrails in the downhill side of the road at that time.

Full speed ahead, construct before design?

In the video assessment by Casey he said it looked like slopes were in the range of 2:1. It's hard to gauge from the drone footage, but to my eye they look a lot steeper than that. They do seem to vary as well as you move along the curve. [Edit: In Casey's second video he acknowledged that slopes appear greater than 2:1.]
Also, any fix seems to be constrained downhill by a creek as to the minimum slope they can lay without additional measures. Hard to see them proceeding successfully without some kind of geogrid or downhill retaining structure. Here's a link to short PDF put out by the Forest Service on slope stabilization. Link

From the image you posted, the slope of the fill appears to be inconsistent (My apologies, I repeated what you stated. In that case, I agree with you). This could be due to poor construction or years of settlement. Either way, it would only be by luck if the design parameters were being met at the steepest inclination. This road has served for many years (I believe I drove it in 1980) so I would consider this issue as a maintenance concern. Perhaps, as with much infrastructure and technology, upgrades are required.

This seems backwards.

It may be a belt and suspenders approach. Rebuild the road safely, then install some ground improvement elements or compaction grouting. It’s difficult to do the ground improvement first when you have a tall scarp hanging over your head.

It's open again, and with little evidence of the collapse ever happening.
About halfway through the video is something about what caused the collapse.

They did put hydroseed down so they did something...

Does the hydroseed just hide the first signs of the next failure?
