The Las Vegas Strip

The Las Vegas Strip is a stretch of Las Vegas Boulevard South in Clark County, Nevada, internationally known for its concentration of resort hotels and casinos along its route. The Strip is approximately 4.2 miles (6.8 km) in length, located immediately south of the Las Vegas city limits in the unincorporated towns of Paradise and Winchester. However, the Strip is often referred to as being "in Las Vegas". Most of the Strip has been designated an All-American Road, and is considered a scenic route at night. Many of the largest hotel, casino, and resort properties in the world are located on the Las Vegas Strip. Fifteen of the world's 25 largest hotels by room count are on the Strip, with a total of over 62,000 rooms. 

One of the most visible aspects of Las Vegas' cityscape is its use of dramatic architecture. The rapidly evolving skyline and constant modernization of hotels, casinos, restaurants, residential high-rises, and entertainment offerings on the Strip, have established it as one of the most popular destinations for tourists in the United States, and the world. 

Historically, the casinos that were not in Downtown Las Vegas along Fremont Street were limited to outside of the city limits on Las Vegas Boulevard. In 1959 the Welcome to Fabulous Las Vegas sign was constructed exactly 4.5 miles (7.2 km) outside of the city limits. The sign is today about 0.4 miles (0.64 km) south of the southernmost entrance to Mandalay Bay (the southernmost casino). 

In the strictest sense, "the Strip" refers only to the stretch of Las Vegas Boulevard that is roughly between Sahara Avenue and Russell Road, a distance of 4.2 miles (6.8 km). However, the term is often used to refer not only to the road but also to the various casinos and resorts that line the road, and even to properties which are not on the road but in proximity. Phrases such as Strip Area, Resort Corridor or Resort District are sometimes used to indicate a larger geographical area, including properties 1 mile (1.6 km) or more away from Las Vegas Boulevard, such as the Hard Rock Hotel & Casino, Rio All Suite Hotel and Casino, Palms Casino Resort and Hooters Casino Hotel. 

The traditional definition considers the Strip's northern terminus as the SLS, though travel guides typically extend it to include the Stratosphere, 0.4 miles (0.64 km) to the north. At one time, the southern end of the Strip was Tropicana Avenue, but continuing construction has extended this boundary to Russell Road. Mandalay Bay is located just north of Russell Road and is the southernmost resort considered to be on the Strip (the Klondike was the southernmost until 2006, when it was closed, although it was not included in Las Vegas Strip on some definitions and travel guides). 

Because of the number and size of the resorts, the Resort Corridor can be quite wide. Interstate 15 runs roughly parallel and 0.5 to 0.8 miles (0.80 to 1.29 km) to the west of Las Vegas Boulevard for the entire length of the Strip. Paradise Road runs to the east in a similar fashion, and ends at St. Louis Avenue. The eastern side of the Strip is bounded by McCarran International Airport south of Tropicana Avenue.

North of this point, the Resort Corridor can be considered to extend as far east as Paradise Road, although some consider Koval Lane as a less inclusive boundary. Interstate 15 is sometimes considered the western edge of the Resort Corridor from Interstate 215 to Spring Mountain Road. North of this point, Industrial Road serves as the western edge. 

The famous "Welcome to Fabulous Las Vegas" sign is located in the median just south of Russell Road, across from the now-demolished Klondike Hotel & Casino. Another similar sign is in the median at the north end of the Strip near the intersection of East St. Louis and South Main Streets. Newer resorts such as South Point and the M Resort are on Las Vegas Boulevard South as distant as 8 miles south of the "Welcome to Las Vegas" sign. Marketing for these casinos usually states that they are on southern Las Vegas Boulevard and not "Strip" properties.
