ABSTRACT:
A cable stayed bridge is constructed as having approach deck spans and at least one cable stayed deck bridge section assembled as a unit by employing the deck surfaces of the approach spans as in situ work surfaces for erecting equal deck lengths of the unit. A bridge pylon is supported on a floatable support and extends through an open gap provided in an approach span deck, and cable stays are extended from the pylon for supporting the deck lengths. The completed unit is moved away from the work surfaces and into alignment with a last of the approach spans, and is permanently anchored in place.
