History:

The Gateway Center in Pittsburgh, Pennsylvania is a high-rise building complex with 1,500,000 square feet (140,000 m²) of office space in four buildings. The plans developed during World War II to redevelop the dense and "blighted" forks of the Ohio River into both Point State Park and a "Gateway" of offices. It was announced as fully financed on September 21, 1949 when the Equitable Insurance Co. of New York agreed to underwrite the project after securing lease agreements such as Westinghouse, Mellon Financial and other  major corporations. Although mainly a run down warehouse district the Center did require the demolition of the 1904 Beaux Arts 11 floor Wabash Pittsburgh Terminal. Gateway Center was purchased in 2004 by Hertz Investment Group, a Los Angeles, California, based real estate investment company, for US$55 million. 

Architects

Eggers & Higgins, architects on the Thomas Jefferson Memorial were the architects for the first three buildings, One, Two and Three Gateway Center. Schell and Decter / Harrison and Abramovitz were the architects for Four Gateway Center.
