Construction Activity Increases on I-17 at Happy Valley and Pinnacle Peak in February

The Arizona Department of Transportation is reconstructing the Interstate 17 traffic interchanges at Pinnacle Peak and Happy Valley roads in north Phoenix. Work is continuing at Pinnacle Peak Road, and construction activity at Happy Valley Road is scheduled to increase beginning in February 2020. ADOT advises those who live, work and travel in this area to plan for impacts that will require motorists to use alternate routes and could increase travel times.

 

Closures and restrictions of I-17, Happy Valley Road over I-17 and/or the on- and off-ramps will begin in February 2020. The first full closures are currently scheduled for Feb. 21—23, when ADOT demolishes the old Happy Valley Road bridge over I-17.

  • Closures and restrictions will occur as needed through fall 2020. ADOT will provide specific information by email and on the project webpage at azdot.gov/I17TrafficInterchanges once schedules are confirmed.
  • Work is scheduled overnights from 10 p.m. to 5 a.m. and on weekend days and nights. However, some long-term, continuous ramp closures will be necessary as crews remove the roundabouts at Happy Valley Road and construct on- and off-ramps for the new diverging diamond interchange.
  • Alternate routes will include Pinnacle Peak or Jomax roads to enter and exit I-17 when ramp closures are in place at Happy Valley Road.
  • Businesses and homes on Happy Valley Road east of I-17 will be accessible from 19th Avenue when I-17 and/or Happy Valley Road over I-17 are closed.
  • ADOT will maintain access to the Park-and-Ride, however detours may be in place at times. ADOT encourages transit users to subscribe to receive email alerts for updated information and allow extra travel time to and from the Park-and-Ride.
  • ADOT will not close Happy Valley and Pinnacle Peak roads at the same time.
