How Las Vegas Is Slowly Building America's Next Mega-City

Las Vegas began with a land auction in 1905, and more than a century later it still grows one federal land sale at a time. In September 2026, the federal government sold the city of Las Vegas about 940 acres in the northwest valley for 94 million dollars, enough for up to 6,000 homes. In a metro of nearly two and a half million people surrounded by open desert, that small purchase was big news. Most of the land around the valley is federal, its water comes from a shrinking Lake Mead, and its high-speed train to Southern California is still waiting on a six billion dollar federal loan. This is the story of how a railroad stop became one of America’s fastest-growing metros, and why its next stage depends on approvals from Washington. It covers a land boundary Congress drew in 1998, a city that cut its water use by about forty percent while adding hundreds of thousands of people, and new Colorado River cuts that pushed Nevada into a federal lawsuit. It also covers a 1958 interchange on Interstate 15 and a second airport planned for a dry lake bed. Forecasters expect Clark County to pass three million people by the mid-2050s. Las Vegas could grow into something much larger if the train, the highway and the new airport tie it to the eighteen million people of Southern California. How fast that happens will be decided mostly in federal offices, not in Las Vegas. Subscribe for more documentaries about how cities grow and change. #LasVegas #Nevada #Infrastate
