Zion National Park: Hwy 9 Closed "Long Term"
Highway 9 through Zion, aka the Zion-Mount Carmel Highway, is completely closed - including the tunnel, due to a rockslide that has caused major damage to the foundation of the road. This means there is virtually NO access to the National Park from the east, and people heading to/from Bryce Canyon or the North Rim of the Grand Canyon are looking at significant detours.
