摘要：
A concrete box girder bridge under construction in Vienna that has an unusually large amount of prestressing and reinforcing steel to handle heavy loads while meeting strict esthetic requirements is described. The Danube River structure will have six traffic lanes on top and carry a rail transit track in each of its two cells. The 2,800-ft structure is fully prestressed longitudinally and vertically, and is prestressed to a lesser degree in its top and bottom flanges.
