ADOT is limiting traffic to one lane this week on State Route 89A during the overnight hours between Flagstaff and Sedona. Restrictions will be in place through Friday morning between 7 p.m. and 7 a.m. as work crews perform striping work on a 11-mile stretch of highway south of Flagstaff. State Route 89A will be restricted to one lane only with alternating north and southbound travel. If you take 89A for a daily commute, you may want to plan for extra time, or use I-17 as an alternate. Drivers should be prepared to stop, proceed with caution and watch for work crews and equipment.
