These dramatic photographs show men working on the catwalks or footbridges connecting the towers of the western span, before the main suspension cables were strung. The ten-foot-wide catwalks, suspended hundreds of feet in the air, consisted of a mesh floor supported by wire ropes. The ferries present at the bottom of each photograph provide a sense of scale.
