ABSTRACT:
A method and apparatus for building bridges from one location to another, and in which the construction activity takes place primarily at such terminal locations. Forms are assembled at one of the locations, such forms establishing the characteristics of the bridge deck to be built. When the forms are completed, they are elevated and suspended upon cables passing between the two locations. The forms are then pulled from one location toward the other, sequentially engaging with previously built and positioned forms until an entire complement of such forms extends between the two locations. The forms are then filled with concrete and finished. The forms provide an exterior finished surface for the bridge structure.
