In May 2014, I took AZ 64 out of the east entrance of Grand Canyon National Park, then US 89 south from Cameron to Flagstaff, much of AZ 64 was relatively freshly repaved, portions of US 89 were freshly repaved, and I passed contruction zones where they were repaving more of it.
Farther north on US 89 (past where we actually were), in the area you describe, there was a landslide/road collapse a year or two back. It shut down US 89 between Bitter Springs and Page. As a result, portions of US 89 were rerouted onto US 89T, a quickly-paved section of one of the Navajo roads (Indian Route 20, IIRC) until the US 89 reconstruction was completed. Then US 89T reverted to being a Navajo road, but instead of the dirt road that had been there a couple years ago, they get a paved (if slightly used) road. And amazingly, the government of Arizona, the Federal government, and the Navajo all came to agree on this pretty quickly, and US 89T was paved and open within a few months.
