ArcelorMittal plate mills in Burns Harbor, Coatesville and Conshohocken are supplying 160,000 metric tons of high-performance steel that will be used in the $3.9 billion “New NY Bridge” project. The 3.1-mile, twin-span, cable-stayed bridge is the single largest bridge construction project in New York’s history, and the largest transportation design-build project to date in the country. The project involves upgrading the Tappan Zee Bridge spanning the Hudson River between Rockland and Westchester Counties. ArcelorMittal USA’s plate mills in Burns Harbor (Indiana), Coatesville (Pennsylvania) and Conshohocken (Pennsylvania) will supply its HPS70W steel to two of the projects’ major steel fabricators for bridge and girder fabrication.
