Introduction to Interstate Highway 93: The Hoover Dam gave birth to the emerging city of Las Vegas and can be said to be the mother of Las Vegas. This was originally a barren and uninhabited land. When the Hoover Dam was being built, a large number of workers gathered here. Water, electricity, and railways provided conditions for the birth of a new city. Today, near the Hoover Dam, you can still find a small, dilapidated and desolate village with broken walls and "Old Las Vegas" written there, which is where the workers camped when the dam was built. . Las Vegas developed from a small desert village. Hoover Dam is a key to the mystery of Las Vegas. Today, Las Vegas has become a city that never sleeps. It is the power from the Hoover Hydropower Station that lights up the colorful neon lights of Las Vegas.
