Via ADOT: Motorists using SR 89A between Sedona and Flagstaff should allow extra travel time as work resumes on improvements between Vista Point Overlook and JW Powell Blvd intersection starting Monday, March 6. SR 89A will be reduced to one lane through the project work zone (milepost 390 - 398) weekdays from 7:30 a.m. to 4 p.m. Flaggers and a pilot car escort will provide alternating travel through the work zone. Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
Starting March 20, this stretch will be closed nightly from 8 p.m. to 5 a.m.
The SR 89A improvement project, which began in 2016, will widen the highway and improve safety on 8.4 miles of SR 89A between Vista Point Overlook and the JW Powell Boulevard intersection. For more information on the project, please visit the project website at: azdot.gov/89A
