STEEL PROVES ECONOMICAL FOR SHORT SPAN BRIDGES

The article describes how New York Department of Transportation opted to use steel after examining construction on four recent short span bridge projects. All of the bridges are plate girder structures and all use ASTM A588 weathering steel. NY DOT feels that costs were held down without sacrificing safety, load capacity or durability. Flexibility also was a factor in choosing steel: where a bridge embodies a curved alignment, steel has more flexibility. Steel bridges are also more adaptable when they carry utility lines, and steel's lighter weight superstructure translates into many cost savings from foundations to erection.
