Construction of the San Francisco-Oakland Bay Bridge began with the groundbreaking ceremony on July 9, 1933. Discussion of connecting both sides of the Bay with a bridge began in the early part of the 20th century.
In 1929, the California Legislature established the California Toll Bridge Authority with the responsibility of connecting the counties of San Francisco and Alameda with a bridge. The construction of the bridge continued through the Great Depression employing many workers on both sides of the Bay.
