Golden Gate Sunrise - a photo on Flickriver

             Creating this renowned bridge was an amazing feat of engineering.

   ► 388,500 cubic yards of concrete, 117,200 tons of steel, 80,000 miles of wire were used to manufacture the  bridge's structure.
    ►Four years and $27 million later, the bridge was completed.
    ►The Golden Gate is a suspension bridge with large cables to support the middle hung from its tall towers.
    ►The bridge spans 4,200 feet.
    ►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 them.
    ►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.
