In the 1980s, a Saudi businessman, Adnan Khashoggi, had a vision of turning Salt Lake City into a major business hub. Forming a U.S. holdings company, "Triad Utah", he planned to build two 43-story skyscrapers, as well as several mid-rise buildings. Khashoggi was implicated in the Iran-Contra scandal and his assets were frozen by the Federal government and the skyscrapers were never built, leaving the current Triad Center with only buildings 3, 4 and 5. Revitalization efforts of downtown continued through the 1990s and 2000s. The old Salt Palace arena was torn down and a new arena, Vivint Smart Home Arena, was constructed to the northwest in 1991. The existing convention center connected to the arena was also demolished and a new convention center of the same name was built on the site. In 1998 the Wells Fargo Center was completed and remains the tallest building in Salt Lake City today (although the LDS Church Office Building appears taller because it stands on higher ground). In 2000, the LDS Conference Center was completed and supplanted the still-existing Salt Lake Tabernacle for conferences of The Church of Jesus Christ of Latter-day Saints. The Gateway, which contains office space, apartment complexes, and an open-air shopping center, was completed in 2001 near the western edge of downtown, replacing an old, run-down industrial area near the railroad. LDS Business College as well as the BYU Salt Lake Center moved downtown to the Triad Center, which was also purchased by the LDS Church in 2004. In 2007, the newest high-rise known as the 222 South Main building began construction. The 21 story building was completed in July 2009.
