High winds are eroding the slopes on northbound Interstate 17, causing rocks to fall onto the highway between Black Canyon City and Sunset Point, according to the Arizona Department of Transportation.
ADOT has stationed equipment and personnel in the area to monitor the situation and keep the roadway clear of hazards.
ADOT advises drivers to slow down and exercise caution on the steep climb northbound from Black Canyon City.
Drivers planning trips are urged to monitor travel conditions by calling 5-1-1 within Arizona, (888) 411-ROAD outside the state or visiting www.az511.gov.
Because weather conditions can quickly evolve, drivers are encouraged to regularly check in with ADOT’s Traveler Information Service. Motorists should delay or detour travel plans if necessary.
