Steel girders hung from concrete cantilevers
Portage Canal bridge in Washington consists of two lateral spans of 170 ft each and central span of 250 ft; latter consists of 140 ft of suspended steel and two 55-ft concrete cantilevers; total width of bridge 26 ft; central 140-ft length is carried by pair of steel box girders lifted to position by two floating rigs. See also Engineering Index 1952 p 116.
