State Route 89 north of Prescott at Hell Canyon (milepost 345) will be narrowed to a single lane from 8:30 a.m. to 5 p.m. tomorrow, Jan. 13 as crews repair potholes on the existing bridge deck.

The lane closure will provide a safe work zone and drivers will be delayed for up to 20 minutes at a time.

ADOT advises drivers to proceed through the work zones with caution, slow down, and be alert for construction equipment and personnel.
