A stretch of U.S. highway 89 in northern Arizona is closed in both directions because of a pavement problem about 25 miles south of Page.
The Arizona department of transportation says traffic will detour around the closure by using U.S. 89a and other U.S. and local highways.
ADOT says what caused a 150-foot section of pavement to buckle shortly after 5:30 a.m. is not related to the weather and might be what the department calls a "geologic event."
According to ADOT, it also isn't known how long the stretch of U.S. 89 will remain closed south of Page. ADOT crews are on scene and are deploying geotechnical engineers to investigate.
An ADOT spokesman suggested the department may be working on the stretch of road for some time.
