• Maximization of safety of the bridge by minimizing stress and deflection in structurally vulnerable connection points and support points through application of concrete filled steel tubes with increased cross sectional efficiency
• Provides excellent quality and constructability and reduces construction time by modularized factory production and on-site assembly construction
• Reduces amount of steel material and negative reaction bridge bearing support no longer necessary when extending span
• Acquisition of durability, earthquake resistance, fire resistance, and weather resistance
• Enables slimmer girder shape compared to normal steel girders and various linear programming and production of different bridge forms
