These are a list of the most basic facts on the Golden Gate Bridge. If you only have limited time to learn a few details, these are certainly the ones to know.
- The Golden Gate Bridge crosses the Golden Gate, a narrow waterway that connects the Pacific Ocean to the San Francisco Bay.
- Cool nights and warm days generate the foggy conditions so common over the Golden Gate in the mornings.
- From the day it first opened until today, the Golden Gate is a toll bridge.
- The Golden Gate is a suspension bridge with large cables to support the middle hung from its tall towers.The vertical cables you see spanning the length of the bridge "suspend" the deck below them.
- Though cable-stayed bridges and suspension bridges look quite similar, they are different in how their cables are attached and thus, how their construction bears the weight. With cable-stayed bridges, all cables are attached to the tower(s), which in turn, bears the load. With suspension bridges, you have main cables running between the two anchorages and suspender cables spanning the length of the bridge, under constant tension.
- The Golden Gate Bridge has two main cables that rest above its 746-foot tall towers and end in a curve at its two opposing anchorages. From the main cables, 250 pairs of suspender cables are inserted. These cablessuspend the Bridge's roadway and help any/all weight travel evenly across the bridge. Because the suspender cables are spaced out, no one cable is under enough stress to snap free.
Creating this renowned bridge was an amazing feat of engineering.
- 388,500 cubic yards of concrete and 117,200 tons of steel were used to manufacture the bridge's structure.
- Four years and $35.5 million later, the bridge was completed.
- The bridge measures a total of 1.7 miles long with the longest span between towers measuring 4,200 feet. It is 90 feet wide and stands 746 feet above the water.
- It is estimated that the actual building of the bridge included 25 million labor hours.
- The cables are actually 27,572 individual tiny wires spun together. More than 80,000 miles of wire were used to make the 7260 feet of cable used in the bridge.
- Each of the two towers is put together with 600,000 rivets.
- Actual paint color of the Golden Gate Bridge is Dulux International Orange.
- As a worst case scenario, the bridge was designed to withstand 90 mph gale-force winds, the weight of bumper to bumper traffic in both directions, tidal surges of 4.6 million square feet per second, and an 8.0 earthquake - all at the exact same time.
- Before this bridge connected Marin County and the city of San Francisco, the only way to cross was by ferry.
- Officials believed the bridge would increase thepopulation of the city of San Francisco and create jobs during the depression
