Construction of the World Trade Center [SEP] Original plans
Rockefeller believed that the area would lose its status as the nation's financial hub if it were not redeveloped. However, the skyscraper, which opened in 1960, attracted far fewer tenants than expected. In 1958, Rockefeller established the Downtown-Lower Manhattan Association (DLMA), which commissioned Skidmore, Owings and Merrill to draw up plans for revitalizing Lower Manhattan. The plans, made public in late June 1960, called for a World Trade Center to be built on a site along the East River, at the South Street Seaport, one of the Lower Manhattan ports that had seen a continuous decline in business over the past decade.
