FRANK LLOYD WRIGHT 
“When San Francisco began to consider duplicating its famous Bay Bridge, running the second alongside the first, Mr. Wright felt that something should be done to stop that. Something better suited to the times and their needs, to the superb scenery of the area, something more scientific, simpler, quieter could be designed. In the summer of 1949 the drawings shown here were made after Mr. Wright was assured of the support of an internationally renowned engineer, J. J. Polivka, residing in San Francisco. 
The bridge, all of reinforced concrete, rests upon a series of great hollow piers, penetrating the earth below the bay like spearheads, almond-shaped in section. These are called “tap-roots” by Mr. Wright … Long, hollow, curved slabs like huge fans spring out and spread 80 feet on each side of a pier, supporting the roadway 70 feet wide, carrying six lanes of traffic and two pedestrian walks. Over the main channel of the bay vast twin arches are flung across 2000 feet of water, leaving 200 feet clearance at the center. Each arch carries traffic in one direction and the two are connected at their crowns by a garden, a pleasant relief and perhaps a stopping point for the traffic.”
