If you mean Hwy. 89, I drove on it with my motorhome from Hwy. 64 all the way to Page a few weeks ago. The road is somewhat rough close to Hwy. 64 but gets much better going north.
I've driven it a few times, last was probably a couple years ago. It's a good and easy two lane road through desolate (and stunning in its own way) Indian reservation land. No problem at all.
gemsworld....Nolan has the road numbers correct. There is also Hwy 89 that runs through AZ.

98 is the route we always take when visiting the 4 corners area. Road is always in good repair.
