The Arizona Department of Transportation is advising drivers, area residents and businesses that a 3-mile section of State Route 89A in Oak Creek Canyon will be intermittently closed overnight on Monday, May 2.

SR 89A will be closed intermittently to traffic through the switchback portion of the roadway between the Pumphouse Wash Bridge and Oak Creek Vista (approximately between mileposts 387 – 390).

The 15-minute, non-consecutive full closures will occur twice per hour from 9 p.m. Monday, May 2 to 6 a.m. Tuesday, May 3.

Drivers should be prepared to stop and use caution around construction personnel and equipment while the overnight closures are in place.

The restrictions are needed so crews can place traffic-control barriers on the roadway for the SR 89A Oak Creek Canyon Improvements project, which includes rockfall mitigation, erosion control and a bridge rehabilitation.
