The idea of an Interstate 11 is not new. The Canamex Corridor, as defined by U.S. Congress in the 1995 National Highway Systems Designation Act, was a joint effort involving Arizona, Nevada, Idaho, Utah and Montana. It prompted the development of a continuous four-lane highway from Mexico through the U.S. into Canada to facilitate trade among the three countries and minimize traffic and congestion.
Next, the U.S. Congress, with its passage of the Moving Ahead for Progress in the 21st Century Act (MAP-21) in 2012, designated the planned freeway between Las Vegas and Phoenix as the Future I-11.
Phase 1 of I-11 in Nevada was a 2.5 mile long, four lane interstate freeway between Silverline Road and Foothills Drive. This project was completed in early 2018.
Phase 2 of I-11 includes construction of 12.5 miles of a four-lane access-controlled freeway around the southern and eastern perimeter of Boulder City from I-515 to US-93 is underway. It is expected to be completed and open to traffic in 2018.
The “Intermountain West Corridor” was a congressionally designated High Priority Corridor from the vicinity of Las Vegas north along US 95 terminating at Interstate 80. In 2015, the FAST Act extended the official designation of I-11 from Las Vegas to I-80 along US 95. This study will help advance the planning efforts for this next segment of I-11.
I-11 is also advancing through a Tier 1 Environmental Impact Statement in Arizona from Nogales to Wickenburg.
