PAGE, AZ - A northern Arizona roadway is closed after the pavement collapsed Wednesday.
The Arizona Department of Transportation says a 150-foot section of US 89 buckled this morning about 25 miles south of Page, Arizona.
Officials say the cause is not weather related and may be a "geologic event."
Drivers trying to get to Page are having to take alternate routes that put them about 45 miles out of their way.
Photos show the road cracked, buckled and dropped below pavement level.
ADOT says it doesn't know how long the road will be closed.
Crews are on scene and are using geotechnical engineers to investigate.
