State Route 89A Improvements (Project Resumed)

SR 89A Switchbacks Now Open

Drivers traveling between Sedona and Flagstaff received welcome news when the Arizona Department of Transportation lifted restrictions and opened the "switchbacks" section of State Route 89A to motorists, well ahead of schedule, late last night.

Originally, the roadway was due to be closed until July 2. However, by allowing the contractor-restricted access to the work zone, a three-mile section of SR 89A (mileposts 387-390) between the Pine Flat Campground and the Vista Point scenic overlook, crews were able to safely complete paving, bridge repair and rock scaling work in an expedited manner that would not have been possible without the full closure of the roadway.

The project began on April 21, with single-lane restrictions in place along the switchbacks. The five-week full closure of the highway had originally been scheduled from May 27 to July 2, but crews were evacuated from the project on May 20 at the start of the Slide Fire.

Work on the project resumed on June 1, shortly after local authorities lifted wildfire-related restrictions near the highway.

ADOT will need to return next month for three weekdays to complete final lane striping through the project corridor. A single-lane restriction will be required and flaggers will be present to guide traffic through the work zone.
