The road appears as though it completely gave way and detached from the slope.
The Navajo Division of Transportation is advising motorists traveling to and from Page to avoid driving on U.S. 89 south of Page.
The division currently is working with the Arizona Department of Transportation and the Bureau of Indian Affairs to address repairs.
None of them yet know how long the repairs will take.
Motorists are advised to travel an alternate route to Page, which will take drivers east on U.S. 160 to SR 98 (about 50 miles) and north on SR 98 to Page. The detour is about 45 miles longer than the direct route.
There is no time frame for when the road will be opened to travelers.
The departments currently are analyzing the road and are trying to figure out what kind of geological event caused the damage.
