Proper Planning and Preparation Prevent Piss Poor Performance.
—British Army maxim
Every great challenge begins with the basics and in the case of the Golden Gate Bridge it starts with removing the protective coating on the cable wires before they are spun into strands that make up the Main Cables.
According to the Golden Gate Bridge website, each of the two Main Cables of the bridge are comprised of 61 bundles (or strands) of 452 carbon steel wires—0.192 inches in diameter—for a total of 27,572 wires. The diameter of one Main Cable is 36 3/8 inches (0.92 m) and the length is 7,650 feet (2,332 m). The total length of galvanized steel wire used in both main cables is 80,000 mi (129,000 km) and that’s enough to wrap around the world three times at the Equator.
In 2002 I walked the length of the West Main Cable and it was a workout. Think about walking a mile and a half up-and-downhill, to-and-from a pair of 50-story skyscrapers, 7/8 of a mile apart. Guess who slept well that night?
