Golden Gate Bridge Facts
This page of the San Francisco Travel Guide provides you with important Golden Gate Bridge facts to enhance your visit to this famous San Francisco icon.
The name "Golden Gate" refers to the strait the the bridge spans, and came about around 1846. It reminded Captain John C. Fremont (an American military officer, explorer, and US senator) of a harbor in Istanbul that he had seen by the name of "Chrysoceras" (or Golden Horn).
He named the strait "Chrysopylae" - a mouthful of a word which means Golden Gate. Not surprisingly (and thankfully too!), Chrysopylae didn't really stick, and people took to calling it the Golden Gate Bridge instead.

- The bridge is 90 feet wide.
- The total weight of the bridge today is 887,000 tons, down from 894,500 tons, due to the replacement of new decking material.
- 11 men died during construction, but 19 men were saved by the innovative use of safety netting below the bridge.
- The steel that was used in the construction of the bridge was manufactured in plants in New Jersey and Maryland, from a company by the name of Bethlehem Steel. To get the steel to San Francisco, it was shipped through the Panama Canal.
- In order to help the bridge manage heavy loads as well as high winds, it is designed to swing 27 feet and flex 10 feet.
- Tolls are only collected traveling southbound. In 2010, the cost is $6 for cash tolls, and $5 for Fasttrak. There are plans to increase the tolls again in July of 2011, however it will not apply to most passenger vehicles.

Facts about the Towers, Cables and Lights:
- The towers stand 746 feet above the water and 500 feet above the road.
- Each tower weighs 44,000 tons.
- There are approximately 600,000 rivets in each of the two towers.
- The width of the main cables is measured at 36 3/8 inches.
- The length of the main cables is measured at 7,260 feet.
- The 2 main cables that pass over the tops of the towers are each made up of 27,572 strands of wire. It took six months to spin the 80,000 miles of wire that run through the two main cables.
Let's ponder that for just a second....
The distance of the Earth's circumference is measured to be roughly 24,900 miles - that means the amount of cable within the Golden Gate Bridge could wrap around the Earth's equator just over 3 times!!
- There are about 128 high-pressure, 250-watt, sodium lamps along the bridge roadway.
- There are twenty-four 400-watt lights that illuminate the towers.
- There are 24 sidewalk lights which are 35-watt, low-pressure sodium lamps.
- An airway beacon tops each tower.
- Irving Morrow (responsible for much of the Art Deco design aesthetic of the bridge) designed the lighting of the bridge, such that there is less light at the top of the towers, giving the appearance that the towers are soaring into the sky, and possibly disappearing into the clouds!
