I-17 Alternatives Study

Project Summary:

The Interstate 17 (I-17) Alternatives Study is a preliminary assessment of the need and feasibility for a new transportation corridor that would provide an alternative to I-17 between Phoenix and Flagstaff. I-17 has limited practical alternatives available. Incident-related delays, as well as those associated with capacity and operational deficiencies, have made roadway reliability a major concern for I-17 users and have prompted ADOT to undertake this very preliminary study. This study is not intended to recommend a specific alignment. Rather, its intent is to recommend whether a more detailed study is warranted. This initial study will address three fundamental questions:

1) Do current and forecast conditions suggest the need for alternates to I-17?

2) Are there feasible alternates to I-17 that can address the needs associated with current and forecast conditions?

3) What additional planning studies, if any, should be done?

Project Update:

The I-17 Alternatives Study as been incorporated into the Statewide Transportation Planning Framework effort, being undertaken by ADOT and regional planners.

ADOT thanks all of you for devoting your time, energy and attention to the I-17 Alternatives Study during the past year. The study effectively identified a number of critical operational issues on I-17 and confirmed a very strong public sentiment to address those issues. It also became evident during the study that these issues should be addressed within the broader context of regional mobility. We now have the Statewide Transportation Framework Studies underway, which are focused on regional mobility. This consolidation of planning efforts will ensure a more unified approach to the corridor and reduce confusion among members of the traveling public.

The information collected as part of the I-17 Alternatives Study will be incorporated into the ongoing statewide studies which are designed to help quantify transportation needs statewide and identify the full range of options to address those needs.
