It's possible that the road through Gardiner, Montana in or out of Yellowstone National park may have reopened

 I'm not sure about this but it is possible that they could have repaired the road enough so that travel into Yellowstone National Park from Livingston, Montana through Gardiner or out that way could be possible now. When I checked on Google Maps I couldn't find any road closed signs on the Google Maps icons so it is possible that way is open again.

Here is another thing I found regarding all this:

We are booking reservations again for Yellowstone Forever Institute summer 2022 Private Tours based out of Gardiner, Montana! Access via the north entrance to Yellowstone National Park is only open to tours at this time. Book an experience with one of our Yellowstone Forever field educators here.

Yellowstone reopened the north loop on Saturday, July 2 to all visitors. Visitors can now access:

• Norris Junction to Mammoth Hot Springs
• Mammoth Hot Springs to Tower-Roosevelt
• Tower-Roosevelt to Canyon Junction (Dunraven Pass)

Visitors can access the south and north loops via the East Entrance (Cody, Wyoming), West Entrance (West Yellowstone, Montana), and South Entrance (Grand Teton/Jackson, Wyoming). Services in the north loop will include general stores at Tower and Mammoth Hot Springs, and gasoline in both locations. Additional services may open in upcoming weeks. As of July 2, visitor entrances from East, West, and South returned to normal entrance procedures. Park staff will continue monitoring visitor use data, traffic counts, and the condition of infrastructure over the upcoming months to ensure visitor usage is not overwhelming capacity. The ALPS may be reinstituted if this becomes the case. Visit Yellowstone National Park’s website for the latest information.
