Interstate 11
Interstate Highway in Arizona and Nevada in the United States
Interstate 11 (I-11), officially known as the Purple Heart Highway, is an Interstate Highway that runs for 54.193 miles (87.215 km) on a predominantly northwest–southeast alignment in the U.S. state of Nevada. It runs concurrently with either or both US 93 and US 95 from the Arizona state line (at the Mike O'Callaghan–Pat Tillman Memorial Bridge over the Colorado River within the Lake Mead National Recreation Area outside of the city limits of Boulder City) to Kyle Canyon Road (SR 157) and Sunstone Parkway in Las Vegas.
The freeway is tentatively planned to run from Nogales, Arizona, to Fernley, Nevada, generally following the current routes of I-19, I-10, US 93, and US 95. Planners anticipate upgrading four existing highway segments to carry future I-11: US 93 in Arizona (from Kingman to the Nevada state line and from Kingman to Wickenburg), US 95 in Nevada (from the Las Vegas Valley to Schurz), and either US 95 (via Fallon) or US 95 Alt (via Yerington) from Schurtz to Fernley. The most recent extension came in 2024, when officials replaced I-515 signs in Las Vegas with I-11 signs and added I-11 signs on US 95 north of Downtown Las Vegas, which extended I-11 northward about 30.5 miles (49.1 km). An extension of the Interstate northward along US 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 to US 93 in Wickenburg is controversial. It is currently facing fierce local opposition and backlash from conservation groups and others, citing costs and environmental, traffic, economic, and safety concerns. The project is on hold pending litigation as of 2025.

Why this record matters
The phrase “interstate Highway in Arizona and Nevada in the United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q807242. Authority coordinates are 36.175, -115.148. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2024 and 2025.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
