Cable Spinning, 1935
With
the completion of the four towers, catwalks were erected between San Francisco
and Yerba Buena Island.
On July 6, 1935, cable spinning began between the towers. Each of the two cables
with 17,464 wires was compressed to a diameter of 28 inches.
From each cable, suspenders were placed to hold the twin decks.
