It took over four years from the start of construction in January 1933, for the Golden Gate Bridge to welcome pedestrians and cars onto its freshly paved roadways in May of 1937, however, the concept for the Bridge was dreamt up well before the 1930s. The first whisper of building a Bridge across the, "Golden Gate Strait," came in 1872 by a railroad entrepreneur.

By 1919, Joseph Strauss had put his hat in the ring for the project and the rest is history.
