When the Golden Gate Bridge was first proposed in the 1920s, most experts considered it impossible. The strait between San Francisco and Marin County was infamous for its deep water, thick fog, and powerful currents. The 4,200-foot span was extraordinary for its time. Critics wrote off the idea as dangerous, impractical, and economically unviable. But there was one man who refused to let the idea die on the drawing board.
The Vision And Obsession Of Joseph Strauss
Joseph Strauss was the engineer who pushed to turn the impossible dream into a reality. Strauss was already known for building small drawbridges, but now he envisioned a suspension bridge to withstand the wrath of nature and a skeptical public. He rallied politicians to his side, secured financing, and hand-picked a team of experts. His leadership transformed the Golden Gate Bridge from a pipe dream into an engineering project of national proportions.

Battling Nature’s Obstacles
The bridge site presented major engineering challenges. The Golden Gate Strait is over 300 feet deep, with violent tides and heavy winds. Fog regularly shrouded the area, reducing visibility to zero and making construction a dangerous business. The engineers had to design foundations capable of anchoring towers in the rocky seabed, while making sure the structure could stand up to the powerful earthquakes that San Francisco is notorious for.

A Bridge Like No Other
The final design, developed under the keen eyes of engineers Leon Moisseiff and Charles Ellis, envisioned a suspension bridge that would be the longest in the world at that time. The two towers soared 746 feet above the water, supporting enormous cables to bear the immense weight of the roadway. Innovations in steel cable spinning and tower construction allowed the structure to safely span the cavernous expanse above the swirling ocean channel…
