Due to the public safety threat posed by the Delta Fire, visitors and tourists will not be granted access through the soft closures to these communities.
UPDATE: Interstate 5 north of Redding remains CLOSED. A second shelter is also operating the National Guard Armory, 618 Everitt Memorial Hwy in Mount Shasta, California.
