History & Asbestos Use
Founded in 1863, the Bethlehem Plant grew to cover over 1,600 acres along the Lehigh River. During World War II, the plant produced armor plate and structural steel critical to the war effort, with asbestos insulation used heavily in high-temperature operations. The plant ceased operations in 1995, and much of the site has since been redeveloped, including extensive asbestos remediation.
