Drivers should anticipate delays and allow extra time, or adjust travel to avoid closures and restrictions. ADOT appreciates your patience as we construct improvements on I-17.

While ADOT and its construction contractors strive to inform the public about planned freeway restrictions, during any complex construction project, there is always a possibility that unscheduled closures or restrictions may occur. During I-17 construction, plan ahead for unexpected restrictions - and remember to slow down in the work zone. The speed limit on I-17 has been reduced to 55 mph from Happy Valley Road to Carefree Highway for the project duration. The speed limit on the frontage roads has been reduced to 25 mph. The reduced speed limits are intended to protect you and your passengers, other drivers and workers in the construction zone.

For information on construction activities, contact Lars Jacoby at 602.712.7176. For general information about I-17 improvements, contact the project email or hotline at 480.890.3055.
