I-11 & Intermountain West

With the I-11 & Intermountain West Corridor Study complete, the I-11 efforts now move to the next phase, with projects and studies continuing in both Arizona and Nevada.

Arizona is continuing the process by beginning a Tier 1 Environmental Impact Statement (EIS) Study to identify a Selected Corridor Alternative between Nogales and Wickenburg, Arizona. More information on the Arizona study, click here.

In Nevada, the Regional Transportation Commission of Southern Nevada (RTC) is leading the effort to complete I-11 from US-95 to US-93 near the Hoover Dam Bypass Bridge, approximately 12.5 miles (Phase 1), while the Nevada Department of Transportation (NDOT) is constructing the portion of I-11 from Railroad Pass to US-95, approximately 2.5 miles (Phase 2). Both phases will be built simultaneously beginning in the spring of 2015 with construction expected to be complete in 2018.
