Abstract of the Disclosure A bridge structure comprising in combination a first elongated member having one end thereof supported upon a first base and the other free end thereof disposed upwardly of the first base, a first elongated boom-like member supported upon one end thereof, the first elongated boom-like member being disposed annularly relative to the first elongated member whereby the free ends of the first elongated member and the first elongated boom-like member are spaced one from another in a first vertical plane, a first tie means extending preferably between the free ends of the first elongated member and the first elongated boom- like member, second tie means extending preferable between the free end of the first elongated member and a first anchor point spaced from the first space whereby an acute angle is formed between the second tie means and the first elongated member, a second elongated member being similar to the first elongated member, the second elongated member having one end thereof supported upon a second base and the other free end thereof disposed upwardly of the second base in similar man- ner to the first elongated member, the first and second bases being positioned in selected spaced relation one to another, a second elongated boom-like member supported upon one end thereof, the second elongated boom-like member being similarly angularly disposed, as the first elongated boom-like member, relative to the second elongated member whereby the free ends of the second elongated member and the second elongated boom- like member are spaced one from another in a second vertical plane substantially parallel spaced from the first vertical plane, third tie means extending preferably between the third tie means extending preferably between the free ends of the second elongated member and the second elongated boom-like member, fourth tie means, similar to the second tie means, the fourth tie means extending preferably between the free end of the second elongated member to a second anchor point spaced from the second base whereby an acute angle is formed between the fourth tie means and the second elongated member, and an elongated traffic deck structure disposed below and longitudinally of the first and second elongated boom-like members and supported therefrom via respectively fifth and sixth tie means connected between preferably the free ends of the first and second elongated boom-like members and the deck structure, the fifth and sixth tie means lying respec- tively in the first and second vertical planes. A novel method of constructing a bridge is also disclosed and which comprises the steps of providing two or more traffic decks and interconnecting the same in tandem arrangement to thereby provide a single elongated traffic deck structure; and sus- pending each of the decks by a cable system of its own where- by a load placed on each of the decks is supported by the cable system thereof.
