L.B. Foster delivers steel grid bridge decking

Pittsburgh, PA-based L.B. Foster Company has begun the delivery of their largest contract for steel grid bridge decking with the rehabilitation of the New York State Bridge Authority’s Newburgh-Beacon span. The fabricator is providing 430,000 sq. ft. of new deck to KiSKA Construction for the replacement of the original 1980 roadway on the twin bridges’ southern span connecting Orange and Dutchess counties.
L.B. Foster worked closely with engineering consultants, Ammann & Whitney of New York City, to design ready-to-install fabricated and precast steel panels sized for specific roadway placement.
“The custom-engineered panels are fabricated to exacting specifications to expedite installation and lessen traffic disruption on the busy span”, said Don Foster, senior vice president, L.B. Foster Construction Products Group.
The innovative steel fabrication reinforces precast concrete to form a composite material that improves the strength-to-weight ratio and adds integrity to the structure.
The material is being manufactured at the L.B. Foster Fabricated Bridge Products plant in Bedford, Pennsylvania. Shipments to the New York jobsite are scheduled to minimize traffic closures and accommodate a night work schedule. The 32-year old bridge carries more than 25 million vehicles each year across the Hudson River on Interstate 84 between the cities of Newburgh and Beacon. L.B. Foster has provided steel grid decking for other critical New York City landmark spans, including the Manhattan Bridge and the raised approaches to the famed Brooklyn Bridge.
