The Las Vegas Valley is a major metropolitan area in the southern part of the U.S. state of Nevada, and the second largest in the Southwestern United States. The state's largest urban agglomeration, the Las Vegas Metropolitan Statistical Area is coextensive since 2003 with Clark County, Nevada. The Valley is largely defined by the Las Vegas Valley landform, a 600 sq mi (1,600 km2) basin area surrounded by mountains to the north, south, east and west of the metropolitan area. The Valley is home to the three largest incorporated cities in Nevada: Las Vegas, Henderson and North Las Vegas. Eleven unincorporated towns governed by the Clark County government are part of the Las Vegas Township and constitute the largest community in the state of Nevada.
Interstate 11 (I-11) is an Interstate Highway that currently runs for 53.9 miles (86.7 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 U.S. Route 95 from the Arizona state line and Boulder City. 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 Las Vegas Valley to Tonopah. 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 has yet to be determined outside of these sections; a number of corridor alternatives, however, have been identified for further study and refinement. The building of I-11 in Arizona is also facing local opposition from conservation groups.
