ABCs of NYC: Pittsburgh steel built the still-awesome Brooklyn Bridge

Pittsburgh Post-Gazette
Huge girders and tightly wrapped cables of Pittsburgh steel were used to erect many of the major structures related to [New York] city’s expansion, business growth and, eventually, its tourism hot spots.
According to the Library of Congress Web site (http://www.americaslibrary.gov), “Pittsburgh steel was used to build some of the most important structures of the modern age: the Brooklyn Bridge, the Panama Canal locks, the Empire State Building, Rockefeller Center, the Oakland Bay Bridge and the United Nations. During World War II, southwestern Pennsylvania became known as America’s “Arsenal of Democracy,” because its mills were working around the clock to make enough steel for America and its allies.”
