Traffic Alerts - SR 89A Oak Creek Canyon Improvements

Plan for intermittent overnight full closures of State Route 89A near Pumphouse Wash Bridge in Oak Creek Canyon on May 2 

Drivers should plan for delays

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.

Construction on SR 89A Oak Creek Canyon Improvements to begin April 18

Plan for lane, vehicle-size restrictions and delays 

The Arizona Department of Transportation is advising drivers, area residents and businesses that work is beginning on the SR 89A Oak Creek Canyon Improvements on Monday, April 18. 

The improvements, which will be constructed at various times through the end of 2023, include rockfall mitigation, erosion control and a bridge rehabilitation along portions of the roadway between Flagstaff and Sedona.

Drivers should be prepared to slow down, stop and use caution around construction personnel and equipment while the following around-the-clock restrictions are in place seven days a week:

  • Portions of SR 89A will be reduced to one lane only of alternating north- and southbound travel between the Pumphouse Wash Bridge and Oak Creek Vista (roughly between mileposts 387 - 390). 
  • Flaggers and temporary traffic signals will direct motorists through the work zones.
  • 8-foot vehicle width and 30-foot vehicle length restrictions will be in place. Due to the narrow roadway, drivers will have to turn around if their vehicle exceeds the width and length restrictions.
  • The speed limit will be reduced in the work zones.
  • The restrictions will be in place through the duration of the project.
