text: In the late 1980s, plans were laid to double the size of the Old Post Office Pavilion's retail space to 75,000 square feet (6,975 square metres) in order to attract more shoppers to the building.Utilizing the provisions of the Public Buildings Cooperative Use Act of 1976, the retail space expansion was financed and completed in 1992. Despite the federal government's intention to demolish the Southern Railway Building and construct a federal office building on the site to complete the Federal Triangle complex, the building stood until 1971. It was demolished in that year, and turned into a parking lot. As many critics had anticipated during Federal Triangle's construction in the 1930s, parking issues grew much worse due to the development's existence. In the late 1950s, a proposal was made to build a commuter and long-distance bus terminal at Federal Triangle as well as a large office building on the space of the parking lot, but the $60 million it would take to build the terminal was never provided. The parking issue became so vexing that the Eisenhower administration ordered its own parking study in 1959.
