It's about four-fifths as long as The Las Vegas Strip
In other words, 5.6420 kilometers is 0.83 times the length of The Las Vegas Strip, and the length of The Las Vegas Strip is 1.2 times that amount.(Las Vegas Boulevard S and W from Russel Rd to Sahara Ave)(Paradise, Nevada through Winchester, Nevada).
Although technically located beyond the city limits of Las Vegas (along with the well-known "Welcome to Fabulous Las Vegas" sign), the stretch of road known as the "Las Vegas Strip" runs 6.8 km along Las Vegas Boulevard South and West from Russel Road at the south end to Sahara Avenue at the north end. The casinos and hotels on the Strip display an estimated total of 24,000 km of neon light tubing.
