The observation deck was opened to visitors in July 2016; the period from July through September 2018 was termed a "test run" or "commissioning" period. Since April 26, 2017, the sightseeing deck on the 118th floor has been open to the public.
Planning models for the Lujiazui financial district dating back to 1993 show plans for a close group of three supertall skyscrapers. The first of these, the Jin Mao Tower, was completed in 1999; the adjacent Shanghai World Financial Center (SWFC) opened in 2008.
