The project consists of twin bridges, running side by side, and built one after the other. The same formwork to support reinforcement was used for both bridges, by merely moving the formwork parallel to itself, after the first bridge was completed. The bridges are of prestressed concrete, and have five spans of 56, 14, 70, 14 and 56 m, with a total length of 210 m. The deck is 2.60 m high and consists of two main girders of constant height, mutually attached by tie members, and resting on twin columns, of considerable slenderness, of reinforced concrete, and approximately 20 m high. The article describes the design procedure, the static structural calculations, the prestressing operations and some constructional details.
