TRANSPORTATION ENGINEERING
Since its introduction in the United States in 1949, precast, prestressed concrete has rapidly become the preferred composite material for bridge design and construction, as well as many other transportation related projects. Today, it remains the solution of choice for transportation agencies and their designers across the country. This growth came, and will continue to come, from the commitment of precast producers to develop, improve, and implement advanced materials, products, and technology all aimed at enhancing the performance of bridges and transportation structures.
