Interstate 17: Anthem Way to Cordes Junction/State Route 69

ADOT has initiated a study to prepare a design concept report and environmental documentation for improvements to the segment of Interstate 17 between the Anthem Way Traffic Interchange (TI) (MP 229) and the State Route 69 TI near Cordes Junction (MP 262+). This section of I-17, designated the "Arizona Veteran's Highway" in 2004, currently consists of two lanes in each direction, traversing rolling terrain in the southern and northern segments and mountainous terrain in the middle segment.

I-17 is part of the National Highway System and connects I-10 with I-40, two of the nation's principal east-west interstate highways. I-17 also provides the major connection between Phoenix and communities in northern Arizona. This project is exploring various means of adding capacity and improving operational safety to I-17.

In recent years, the study has focused on long-term solutions between Black Canyon City (MP 245) and Cordes Junction (MP 262+).  However, the current effort focuses on adding capacity in the near-term between Anthem Way and Sunset Point (MP 252).

The study segment is located in a rural area of Maricopa and Yavapai counties. The Agua Fria National Monument, administered by the Bureau of Land Management, is located immediately east of the I-17 right-of-way from approximately MP 245 to MP 260.

Study Update: Recommended Build Alternative

Anthem Way TI to Black Canyon City TI (MP 245):  The Recommended Build Alternative includes adding a lane in both directions, widening the northbound roadway toward the median side and widening the southbound roadway toward the median in some segments and toward the outside in other segments.

Black Canyon City TI to Sunset Point TI:  The Recommended Build Alternative includes constructing two flex lanes next to but separated from the southbound roadway by a concrete barrier.  The flex lanes would be open to either northbound or southbound traffic depending on the peak traffic direction.  Access to the flex lanes would be controlled by gates or a similar mechanism.
