Interstate 11
Interstate 11 (I-11) is an Interstate Highway that currently runs for 54.193 miles (87.215 km) on a predominantly northwest–southeast alignment in the U.S. state of Nevada, running concurrently with either or both U.S. Route 93 (US 93) and US 95 from the Arizona state line at Mike O'Callaghan–Pat Tillman Memorial Bridge over the Colorado River within Lake Mead NRA outside of the city limits of Boulder City to 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) 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 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[update].
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 I-15. 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 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.
The highway currently begins at the Arizona state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge, then runs along the 15-mile (24 km) Boulder City Bypass around Boulder City, which opened on August 9, 2018. It is signed concurrently with US 93 throughout. An at-grade intersection just north of Buchanan Boulevard overpass is for emergency vehicles only. At mile 14, I-11 intersects and joins with US 95 heading north. Continuing northwest, the highway runs along the former I-515 around Henderson to the Henderson Spaghetti Bowl interchange with I-215 and State Route 564 (SR 564).
In 2024, I-11 was extended through the Las Vegas Valley along US 93/US 95 (the rest of the alignment of former I-515) to Downtown Las Vegas and I-15, then running concurrently with US 95 northwest to SR 157. When this segment was designated, I-515 was decommissioned. Studies to extend I-11 from SR 157 northward to Mercury were started in late 2023.
From I-15 to Elkhorn Road, I-11 and US 95 have HOV lanes that are currently enforced by both LVMPD (aka Metro) and NSP (formerly NHP).
As recently as 1997, US 93 was mostly a two-lane road between Wickenburg and Hoover Dam and was known for its dangerous curves and hills in the stretch between Wickenburg and I-40. In the late 1990s, the Arizona Department of Transportation (ADOT) began widening US 93 to four lanes and, in some areas, building a completely new roadway. In other places along the route, ADOT simply repaved the old highway and built two new lanes parallel to it. ADOT also began studying the possibility of adding grade separations to US 93 near the Santa Maria River to make the road a full freeway.
