ADOT crews will be working this week in the Prescott Valley area, which could mean travel delays for some. Crews will be doing crack-seal work in the overnight hours on State Route 89A between Willow Creek Road and Robert Road beginning Monday night and lasting through Thursday. Crews will be doing the work between 7 p.m. and 5 a.m. State Route 89A will be narrowed to one lane in each direction while work is underway. Speed limits will be lowered from 45 to 35 miles per hour in work zones. During work, drivers should proceed through work areas with caution.
