A 150-foot section of U.S. 89 south of Page that buckled and sunk four feet Wednesday might have been caused by a "geologic event," according to the Arizona Department of Transportation.
The road collapsed at mile post 526 just 2.5 miles north of the intersection with U.S. 89A, about 25 miles south of page, according to an ADOT spokesman. He said the incident was not related to the weather.
The road was closed in both directions and there was no estimation when the highway would reopen, said an ADOT spokesman.
ADOT officials said northbound U.S. 89 was closed at the U.S. 89A junction, which takes motorists west toward Jacob Lake. In Page, U.S. 89 was closed at the junction with State Route 98.
Northbound motorists were being routed to U.S. 160 east to State Route 98, and north on SR 98 back to U.S. 89 in Page. The detour is about 45 miles longer than the direct route, the spokesman said.
The Coconino College campus in Page was also closed because of the road closure.
DPS reported a number of collisions within the collapse, but none appeared to be serious. No injuries were reported.
No other information was immediately available.
