Detailed answer

The Welcome to Fabulous Las Vegas sign has been affected by the development of the Las Vegas Strip, with the sign being relocated in 2009 to accommodate the widening of Las Vegas Boulevard. The sign's original location was near the intersection of Las Vegas Boulevard and Sahara Avenue, but it was moved to its current location to make way for the construction of new hotels and casinos. Despite the relocation, the sign remains a popular and iconic symbol of Las Vegas.
