| San Francisco Golden Gate Bridge Built 1933-1937 |
Engineered by Joseph Strauss and designed by Charles Ellis between 1916 and 1928, the Golden Gate Bridge’s 4,200 foot long suspension spans were the longest bridge spans yet designed, the iron towers were among the world’s tallest (746 feet tall) and the suspension cables designed to pull, flex, bend and bow were an engineering feat that had yet been accomplished. (Each cable is made up of 27,572 perfectly aligned, individual steel wires that weigh a total of 24,500 tons and measure 3 feet in diameter.)
Every detail of the bridge is facinating to me. The color, international orange, selected to stand out in the fog, the minimalist art deco tower design, the delicate lines of verticle cable, the picturesque views of Marin and San Francisco but what holds my facination most is that the design was concepted and constructed to support variances in load, weather and temperature. Built to sway 27 feet side-to-side and move up and down as much as 16 feet due to load, the Golden Gate Bridge moves almost as much as the narrow straight it is built above—ingenious!
Thank you Joseph Strauss and Charles Ellis. Your vision, determination and perserverance lead to pure design brilliance.
