     GOLDEN GATE BRIDGE
     The second largest suspension
     bridge in the world. -It spans the golden gate-a mile wide
     straight between the Pacific Ocean and the San Francisco Bay-
     and connects San Francisco with Marin County to the North. The
     bridge has a 4200 foot main span., second only to the
     Verranzo-Narrows Bridge in New York Harbor, and a total length
     of 8,981 feet. The $35 million dollar structure was started in
     1933 and opened in 1937. Joseph B. Strauss was the chief
     enaineer and Othmar H. Amman (q.v.) was a consultant.
      The two steel towers of the
     bridge, each 746 feet high, are the tallest bridge towers in
     the world. The towers, painted bright orange, support two
     cables, 36.5 inches in diameter, spaced 90 feet apart. The
     pier supporting the south tower is founded on bedrock 100 feet
     below the water surface. The pier, built 1125 ft from shore,
     is exposed to ocean storms and strong tidal currents. The
     bridge carries a roadway, 60 feet wide, divided into six lanes
     for vehicular traffic and there are plans to add a second lower
     deck. The view from the roadway about 250 ft above the water
     is spectacular.
