US Route 89 Landslide


In the early morning hours of Feb. 20, 2013, a landslide ripped through a section of US 89 along a mountain slope about 25 miles south of Page, buckling more than 150 feet of the roadway and tearing the pavement up in six-foot-high sections.

The significant roadway damage forced the Arizona Department of Transportation to immediately close a 23-mile-long stretch of the highway (at mileposts 523-546) between the US 89A junction near Bitter Springs to the State Route 98 junction near Page.

ADOT is working to rebuild the highway as soon as safely possible. Construction is currently underway, and is anticipated to be completed by late spring 2015.


In late 2013 ADOT opened the 44-mile-long US 89T route, which runs parallel to US 89 from The Gap to LeChee. The detour is accessible from US 89, approximately 17 miles north of the US 160 junction (Tuba City exit). Previously a Navajo Nation roadway, US 89T will be maintained by ADOT while it is in use as a detour.
