On December 8, 2008, site improvements were completed in the median allowing official public access to the welcome sign for the first time. The $400,000 project included a parking lot with 12 parking spaces and two loading areas for buses and limousines, as well as a paved walkway leading from the parking to the sign viewing area. The improvements were successful, and the small parking lot was soon overwhelmed by an ever-increasing number of visitors to the sign.
