Golden Gate Bridge Facts

  1. The color of the Golden Gate Bridge is orange vermillion or "International Orange." Architect Morrow chose the color because it blends well with the bridge's natural setting. It is also visible in fog.

  2. People often say that the bridge is painted end to end in a continuous manner -- that when one end is reached, the painting begins again toward the other side. It doesn't work this way exactly, but the paint is regularly touched up as needed.

  3. During construction, a safety net was draped under the floor of the bridge, from end to end. The net saved the lives of 19 men who became known as the "Half Way to Hell Club."

  4. The Golden Gate straight over which the bridge was built regularly has currents ranging from 4.5 to 7.6 knots.

  5. The Golden Gate Bridge was the longest suspension bridge until the Verrazano Narrows Bridge opened in New York in 1964.

  6. Total construction cost was $35 million.

  7. The bridge's tower lighting wasn't installed until 1987 -- on the bridge's 50th anniversary.

  8. The original two-tone fog horns on the Golden Gate Bridge lasted 50 years and were replaced with single-tone horns in 1985. During foggy season they sound for more than five hours a day.

  9. Golden Gate fog is known as "advection fog." Advection fog forms when humid air from the Pacific swoops over the chilly California current. The Golden Gate Bridge has an influence in directing the fog as it pushes up and pours around the bridge.
