I-11 & Intermountain West Corridor Study

In the summer of 2014, the Arizona and Nevada Departments of Transportation completed the two-year Interstate 11 (I-11) and Intermountain West Corridor Study. Congress recognized the importance of the portion of the Corridor between Phoenix and Las Vegas and designated it as future I-11 in the recent transportation authorization bill, Moving Ahead for Progress in the 21st Century Act (MAP-21). The study included detailed corridor planning of a possible interstate link between Phoenix and Las Vegas, and high-level visioning for extending the corridor south to Mexico and potentially north to Canada.

Some sections of this corridor will be constructed or enhanced in coming years, while the majority of the corridor remains in the long range planning phase. The results of this study will need to go through environmental, funding, design and right-of-way reviews before potentially being constructed in phases.
