Questions & Answers

Q: Why was the construction of the Golden Gate Bridge seen as impossible?

The combination of the width and depth of the Golden Gate Strait, along with the harsh environmental conditions, made many believe that building a bridge was impossible.

Q: How did the Golden Gate Bridge get funding during the Great Depression?

The city's authorities proposed a bond measure, securing funds against the properties of their citizens, and it was put to a referendum and approved despite concerns about feasibility.

Q: How were the suspension cables of the Golden Gate Bridge created?

The cables were formed by dragging wires across the bay, bundling and draping them back and forth until they formed the two main cables of the bridge. Workers worked in extreme conditions and high winds to achieve this.

Q: How has the bridge been maintained over the years?

Maintenance of the bridge is a continuous task, with a team of 110 full-time personnel responsible for various aspects. This includes repainting based on corrosion monitoring and periodic replacements of components.
