Detailed answer

The Welcome to Fabulous Las Vegas sign has undergone several restorations and maintenance projects over the years to preserve its original design and condition. In 1984, the sign was restored to its original condition, and in 2009, it was relocated to its current location to accommodate the widening of Las Vegas Boulevard. The sign is regularly maintained by the Neon Museum, which is responsible for preserving and restoring many of Las Vegas' historic neon signs.
