The Hit The Trail site stated that there was a "geologic event" on this stretch of hwy 89. The road "broke and shifted", unknown when it will reopen. Photos on this site show how much damage was done.
" We had an exciting even occur on the highway that takes you from Flagstaff/South Rim to Lake Powell/Page and at the junction to the North Rim (Hwy 89 and 89A)! 150 of roadway shifted, broke and settled leaving it impassable yesterday morning. They are saying it was a geologic event! Wow! You've got to check these photos out. Amazing!!! They don't know when the road will be fixed and reopened, but it is obvious that it will be quite some time! Road collapse closes Highway 89 south of Page azdailysun."
