'''Interstate&nbsp;11''' ('''I-11''') is an [[Interstate Highway]] that currently runs for {{convert|54.193|mi|km}} on a predominantly northwest–southeast alignment in the U.S. state of [[Nevada]], [[concurrency (road)|running concurrently]] with either or both [[U.S. Route&nbsp;93]] (US&nbsp;93) and [[U.S. Route 95|US&nbsp;95]] from the [[Arizona]] state line at [[Mike O'Callaghan–Pat Tillman Memorial Bridge]] over the [[Colorado River]] within [[Lake Mead National Recreation Area|Lake Mead NRA]] outside of the city limits of [[Boulder City, Nevada|Boulder City]] to [[Las Vegas]].

The freeway is tentatively planned to run from [[Nogales, Arizona]], to [[Fernley, Nevada]], generally following the current routes of [[Interstate 19|I-19]], [[Interstate 10|I-10]], US&nbsp;93, and US&nbsp;95.<ref name="adot1215" /> Planners anticipate upgrading four existing highway segments to carry future I-11: US&nbsp;93 in Arizona from [[Kingman, Arizona|Kingman]] to the Nevada state line, and from Kingman to [[Wickenburg, Arizona|Wickenburg]] and US&nbsp;95 in Nevada from the [[Las Vegas Valley]] to [[Schurz, Nevada|Schurz]], and either US&nbsp;95 (via Fallon) or US&nbsp;95 Alt (via Yerington) to Fernley.<ref> {{cite web |title = Future I-11 Alternatives Analysis - Las Vegas Valley to I-80 |url = https://www.dot.nv.gov/projects-programs/programs-studies/future-i-11-alternatives-analysis-las-vegas-valley-to-i-80 }} </ref> The most recent extension came in 2024, when officials replaced [[Interstate 515|I-515]] signs in Las Vegas with I-11 signs and added I-11 signs on US&nbsp;95 north of [[Downtown Las Vegas]], which extended I-11 northward about {{convert|30.5|mi|km}}.<ref name="I-515replaced">{{cite web |last = Vigil |first = Joe |date = May 22, 2024 |title = Interstate 11 signs going up in Las Vegas; Mexico-to-Canada interstate plans move forward |url = https://www.fox5vegas.com/2024/05/22/interstate-11-signs-going-up-las-vegas-mexico-to-canada-interstate-plans-move-forward/ |access-date = May 22, 2024 |website = www.fox5vegas.com |language = en }}{{cite web |title = Construction of Interstate 11 Moves Ahead in Nevada |url = https://www.roadsbridges.com/highway-construction/news/55054608/construction-of-interstate-11-moves-ahead-in-nevada |website = Roads and Bridges |access-date = June 19, 2024 |language = en |date = May 29, 2024 }}</ref> An extension of the Interstate northward along US&nbsp;95 to [[Mercury, Nevada]], is planned after that. An exact alignment for I-11 south of Wickenburg has yet to be determined; a number of corridor alternatives, however, have been identified for further study and refinement.

The building of I-11 in Arizona as a freeway bypass from I-19 in [[Sahuarita, Arizona|Sahuarita]] to US 93 in Wickenburg is controversial as it is currently facing fierce local opposition and backlash from conservation groups and others citing costs, environmental, traffic, economic and safety concerns as the project is currently on hold pending litigation {{As of|2025|lc=y}}.

The numbering of this highway did not initially fit within the usual conventions of the existing Interstate Highway grid as the whole route was east of [[Interstate 15|I-15]]. [[Interstate 17|I-17]] was already built to the east of the I-11 alignment in Arizona, making it impossible to fit this freeway's Interstate number into the national grid and remain within the traditional numbering convention. I-11 being extended along US&nbsp;95 through Las Vegas and crossing over I-15 remedied this situation since it put a portion of I-11 west of I-15 and thus in line with the national grid numbering conventions.<ref name="I-515replaced"/>
