ArcelorMittal plate mills in Burns Harbor, Coatesville and Conshohocken are to supply 160,000t of high performance steel to be used in the USD 3.9B New NY Bridge project.
The 3.1mi 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 United States. The project involves upgrading the Tappan Zee Bridge spanning the Hudson River between Rockland and Westchester Counties in New York.
ArcelorMittal USA are supplying their HPS70W high-performance steel to two of the project’s major steel fabricators, High Industries and Hirschfield Industries for bridge and girder fabrication. A significant amount of Burns Harbor material was also supplied to Berg for the bridge pilings earlier in 2013.
The first span of the new twin-span bridge is scheduled to open in 2016 and should be completed in 2018. The new bridge will be designed and constructed to last 100 years without major structural maintenance. The bridge is being designed and built by Tappan Zee Constructors (TZC), and a consortium of design, engineering and construction firms, including Fluor, American Bridge, Granite and Traylor Bros.
