The Arizona Department of Transportation is asking the public about the speed limit along a stretch of Interstate 17 in Phoenix.

ADOT has commissioned an independent study to determine an appropriate speed limit for I-17 between the I-10 “Split” interchange near Phoenix Sky Harbor International Airport and Peoria Avenue.

 The speed limit for that part of I-17 is 55 mph. 

The speed study follows passage of legislation that calls for a minimum speed limit of 65 mph on any interstate highway in counties with a population of 3 million or more people.

SB 1102 also stipulates that a lower speed limit can be set if certain conditions are met, including:

• A lower limit is deemed necessary based on an independent engineering study or roadway assessment.
• The overall system capacity and mobility along the freeway will not be reduced.
• An opportunity for public input is provided.

The I-17 speed limit study is scheduled for completion in mid-October.
