Golden Gate Bridge History

The Golden Gate Bridge had the longest suspension bridge span in the world when it was completed in 1937, and has become an internationally organized symbol of San Francisco. The bridge connects the city of San Francisco on northern to Marin Country. Although the idea of a bridge spanning the Golden Gate was not new, the proposal that eventually took root was made in a 1916 article by former engineering student James Wilkins.

Design

Irving Morrow, a relatively unknown residential architect, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements such as the streetlights, railing, and walkways. The famous International Orange color was originally used as a sealant for the bridge. Senior engineer Charles Alton Ellis, collaborating remotely with famed bridge designer Leon Moisseiff, was the Principal engineer of the project.
