What to Expect
Lane restrictions may be used at times on SR 89A throughout the duration of the project. However, to complete the work in a safe and timely manner, a full closure of SR 89A through the switchbacks, which have steep grades with little to no shoulders, will be necessary for up to five weeks following the Memorial Day holiday and prior to the July 4 holiday (May 27-July 2).
Access to Oak Creek Canyon and Sedona will be maintained throughout the project via I-17 and SR 179. During the full closure, signs and message boards will be used along I-17 and SR 179 to direct travelers to their destinations. Access will be maintained at all times for emergency vehicles.
