ADOT will reduce traffic on a three-mile stretch of State Route 89A in Oak Creek Canyon Monday. Officials say the highway will be restricted to one lane only of alternating north and southbound travel between 7 a.m. and 5 p.m. The area is just north of Sedona going for three miles. Crews will be performing maintenance work along the shoulders of the highway. Drivers should slow down and proceed through the work zone with caution and watch for construction workers and equipment. The speed limit will be reduced to 25 miles-per-hour.
