Abstract: The invention relates to a method of constructing a cable-stayed bridge extending between at least three towers. Initially, a horizontally extending truss spanning from a first tower to a second tower is moved longitudinally to be projected from the second tower to a third tower. The truss is then elevated. A plurality of stay cables are then strung from an elevated location on the second tower to a series of temporary connections to the truss on both sides of the second tower. A deck portion is then constructed on the truss on both sides of the second tower, and the cables that are not connected to the truss are connected to this deck portion. Finally, the cables are disconnected from the truss and the truss and hence the deck portion are lowered, causing the cables to support the weight of the deck and to acquire the desired tensional stresses. The procedure is faster than hitherto know methods of constructing this type of bridge.
