Long steel truss, mostly of pipe, was assembled at remote river in Bolivia for use in moving 60ton precase post-tensioned girders 126 ft long across fast flowing Yapacani River; launcher unit cantilevered over full span when moving ahead, then was supported on pier while moving four lines of girders to position; launcher traveled on wheels salvaged from B-29 airplanes; similar wheels, mounted in pipe frame, were used to move girders to bridge and out over structure as erection advanced.
