Unistress Corp. designs and manufactures prestressed concrete building materials in the Northeast. With one of the largest facilities in North America, the company specializes in large-scale structures such as concrete cooling towers, industrial plants and retail buildings, and major roadway overpasses.

Among other ventures, Unistress was tapped for a major roadway reconstruction project: replacing the Tappan Zee Bridge, which has connected New York state’s Westchester and Rockland counties via a 3.1-mile-long span across the Hudson River since 1955. As a part of the bridge renovation, the constructors opted for precast concrete deck panels from Unistress.
