OAK CREEK – As the battle against the Slide Fire in Oak Creek Canyon winds down, the ongoing highway-improvement project along the “switchbacks” section of State Route 89A will resume this weekend.

The previously-scheduled closure of the three-mile stretch of SR 89A between the Pine Flat Campground and the Vista scenic overlook south of Flagstaff will remain in place for several weeks while crews remove loose rocks above the switchbacks, complete other safety improvements and resurface the highway.

SR 89A will reopen to traffic before the Fourth of July weekend.

The full closure of the highway had been scheduled to start on Tuesday (May 27) but crews were temporarily pulled off the project more than a week ago (Tuesday, May 20) due to the Slide Fire.

DETOUR INFO: While the switchbacks section along SR 89A is closed, ADOT recommends drivers use Interstate 17 and State Route 179 to travel between Flagstaff and Sedona.
