State Route 89A is closed at the Oak Creek Canyon switchbacks due to a sinkhole which appeared on the roadway during the weekend. The highway is closed in both directions between mileposts 387-390, between Sedona and Flagstaff. Motorists can use Interstate 17 as an alternate route.

The closure is expected to remain while investigations regarding the cause of the sinkhole and repairs can be made. An announcement will be made once the situation has been remedied and the switchbacks are available for use. Investigations are underway and are expected to continue through the week.
