The Las Vegas Strip (also known as The Strip and to local residents as The Boulevard) is 4 mi (6.7 km) of Las Vegas Boulevard South partly in Las Vegas, Nevada, United States, that has been designated an All-American Road. Many of the largest hotel, casino and resort properties in the world are located on The Strip. Over the years, Las Vegas Boulevard South has been called Arrowhead Highway, "Salt Lake Highway", U.S. Highway 91, and "Los Angeles Highway". The Strip was reportedly named by police officer Guy McAfee, after his hometown's Sunset Strip, in Los Angeles.
The Strip runs from the Stratosphere at the northern end to Mandalay Bay on the southern end. Of the 4 miles, nearly 3.5 miles of it is located in the township of Paradise, Clark County. Depending on the definition, very little to none of it is within the Las Vegas city limits. McCarran Airport (LAS) is located at the southern end of The Strip, along with the famous Welcome to Fabulous Las Vegas sign, which also appears in the median of Las Vegas Boulevard at the north end near the intersection of E. St. Louis and S. Main Street. The "South Strip" is used to describe the section of Las Vegas Boulevard between Sunset Road or Blue Diamond Road and St. Rose Parkway.
