Back home, Allegheny City and Pittsburgh continued to grow, and with the Stocktown Avenue AGH hemmed in by railroad tracks, the hospital board again looked for a location to build a new hospital. They found one 2,000 feet to the north. New York architecture firm York and Sawyer was hired to draw plans for what would be one of the nation's first “skyscraper” hospitals, and by 1929, construction was underway. The cornerstone was laid in 1930, and the plastering was almost finished by 1931. The Great Depression interrupted construction, but the U.S Public Works Administration loaned AGH the $2 million that it needed to complete the project, and on June 24, 1936, the third iteration of Allegheny General Hospital was formally dedicated. The 22-story, $8 million hospital had 1,300 separate rooms, including 162 private patient rooms. Built in the Lombard architectural style, the cream-brick tower was an instant landmark structure, visible for miles; the high rise is now designated a Pittsburgh History and Landmarks Foundation historic landmark. The new hospital featured multiple kitchens, a pediatric wing, maternity wards, an x-ray department and a cardiology department; pneumatic tubes, call boxes and a state-of-the-art phone system helped hospital employees communicate.
