context_page_description: Interstate 11 is an Interstate Highway that currently runs for 22.8 miles on a predominantly northwest–southeast alignment in the U.S. state of Nevada, running concurrently with U.S. Route 93 between the Arizona state line and Henderson. The freeway is tentatively planned to run from Nogales, Arizona, to the vicinity of Reno, Nevada, generally following the current routes of I-19, I-10, US 93 and US 95. Planners anticipate upgrading two existing highway segments to carry future I-11: US 93 in Arizona from Wickenburg to the Nevada state line on the Mike O'Callaghan–Pat Tillman Memorial Bridge over the Colorado River and US 95 in Nevada from the edge of the Las Vegas Valley to Tonopah. An exact alignment for I-11 has yet to be determined outside of these sections or through the Las Vegas Valley; however, a number of corridor alternatives have been identified for further study and refinement.
  As originally proposed in the 2012 Moving Ahead for Progress in the 21st Century Act, the highway would only run from Casa Grande, Arizona, to Las Vegas. This was to provide a Las Vegas–Phoenix freeway link.
context_section_description: The southern terminus of the freeway would be at Interstate 19 Business Loop in Nogales, Arizona, concurrent with that of I-19 proper, or follow Arizona State Route 189 from its intersection with I-19 to the Mariposa Port of Entry where it continues south as Mexican Federal Highway 15D, creating a Nogales, Arizona/Nogales, Sonora Metro Area Bypass for high-density CANAMEX Corridor traffic. As originally envisioned, the freeway would then join I-10 in Tucson and continue to Casa Grande. However, corridor alternatives were studied, and the draft tier 1 environmental impact statement selected a recommended corridor alternative that would split from I-19 near Sahuarita and travel around the Tucson Mountains as a Tucson bypass route, then travel parallel to I-10 until Casa Grande. The two interstates would be within miles of each other, and a short connection to I-10 is proposed in Marana.
  At or near the interchange with I-8 and I-10 in Casa Grande, the freeway would split from I-10 and travel in a generally westward and then northward direction as a bypass route around the Phoenix metropolitan area. Two general corridor alternatives have been identified for this bypass section. One recommended alternative would have the highway running concurrently with I-8 west to Gila Bend, turning north to its interchange with I-10 in Buckeye or Tonopah. The second recommended alternative would have the highway run concurrently with I-8 east to an intersection with either Loop 303 or the Hassayampa Freeway, and then follow some combination of those highways, Arizona State Route 30, or AZ 85 to an intersection with I-10 in or near Buckeye.
  North of I-10 in Buckeye or Tonopah, the study has identified a general corridor roughly parallel to the Hassayampa River with two more specific corridor alignments. The first would create a new highway running north to the US 60/SR 74 intersection in Morristown before turning northwest to run concurrently with US 60 to its intersection with US 93 in Wickenburg, thereafter running concurrently with US 93 to the northwest. The second alignment would follow the alignment of the Hassayampa Freeway as proposed by the Maricopa Association of Governments to an intersection with US 93 northwest of Wickenburg in Yavapai County.
  The highway would then run concurrently with US 93 through northern Arizona, including a concurrency with I-40 in and near Kingman. The highway would then cross the Mike O'Callaghan-Pat Tillman Memorial Bridge into Nevada.
