The Golden Gate Bridge is painted "International Orange." This bright color is a good choice, because it helps ships see the bridge, even in bad weather. What colors would be bad choices for the bridge?
How long did it take for painters to remove the lead-based paint on the Golden Gate Bridge and replace it with zinc-based paint?

This painter is working on top of the south tower of the Golden Gate Bridge. What is his elevation?
- The Golden Gate is the narrow strait that connects the San Francisco Bay and the Pacific Ocean. The open "gate" is formed by the Marin Headlands to the north and the San Francisco Peninsula to the south. The Marin Headlands are largely undeveloped land, while the San Francisco Peninsula is home to one of the most densely populated cities in California.
- The Golden Gate Bridge was completed in 1937. Ever since then, the color of the bridge has been "International Orange." It was colored this vibrant shade to help passing ships see it through the thick fog of the region.
- The original "International Orange" contained a high amount of lead, which can be toxic. A program to remove the original paint was begun in 1965 and completed in 1995. The newer paint is zinc-based.
- The high salt content of the air above the Golden Gate corrodes, or damages, the paint on the Golden Gate Bridge. Today, more than 30 painters are required to constantly touch-up the corroded surface of the bridge.
- Golden Gate Bridge painters cannot be acrophobic (afraid of heights)! The bridge carries six lanes of traffic about 75 meters (246 feet) above the Golden Gate. The bridge's two towers rise another 152 meters (500 feet) above that.
