San Francisco in San Francisco City and County, California — The American West (Pacific Coastal)
Hanging the Roadway Deck
An advantage of a suspension bridge is that once the towers, anchorages, and main cables are installed, no temporary supports are needed under the bridge to build the roadway deck. The deck is built in sections, proceeding out from the towers in a balanced way, each section hung from the suspenders.
The final piece of the overall structure, the roadway deck structure with its paving, was in place by April 19, 1937, about a month before the Bridge opened.
