Beginning June 12, 2022, unprecedented amounts of rainfall caused substantial flooding, rockslides, and mudslides within Yellowstone National Park. Historic water levels caused severe damage to roads, water and wastewater systems, power lines, and other critical park infrastructure.

Less than three weeks after this major flood event, the south and north loops of the park opened to the visiting public, accounting for 93 percent of the roadways in Yellowstone National Park. The Alternating License Plate System (ALPS) which was implemented on June 22, 2022 was suspended on July 2.

The North Entrance Road (Gardiner, Montana to Mammoth Hot Springs) and Northeast Entrance Road (Cooke City/Silver Gate, Montana to Tower-Roosevelt) remain closed to visitor vehicular traffic while temporary repairs are completed. Visitors may access the park on foot through these entrances in order to recreate (fish and hike) in areas not identified as closed. The park will evaluate authorizing bicycle use through these entrances up to damaged road sections in the near future.

Reconnecting the park to Gardiner and Cooke City/Silver Gate remains Yellowstone's highest flood recovery priority. These communities are open with access to the park as described above.
