BAY BRIDGE HISTORY
Bay Bridge Celebrates 79th Anniversary of Groundbreaking
On July 9, 1933, the California Department of Public Works broke ground on the San Francisco-Oakland Bay Bridge. Crowds gathered at Yerba Buena Island to celebrate the world’s longest steel structure. The 1-day ceremony included performances by the Young Women of Bay Cities and the United States Navy Band; an airplane flight that linked Rincon Hill and Oakland with a symbolic bridge of smoke; and a simultaneous detonation of blasts at Yerba Buena Island, San Francisco and Oakland by then-President Franklin D. Roosevelt.
The Original Bay Bridge
Cynics believed that the bridge would be impossible to build due to the potential impact of turbulent waters and gusty winds. Engineers had assumed that the area's high winds posed a greater threat than earthquakes, despite the bridge's proximity to two major fault lines. The varying soils and water depths, the inaccessibility to bedrock, and the unique design challenges inherent in developing a bridge to span eight miles across the Bay led some to believe that building such a bridge was unthinkable.
The largest and most expensive bridge of its time, the Bay Bridge faced not just natural obstacles, but political hurdles as well. There had been discussion of building a bridge between San Francisco and Oakland since the 1870s, but construction did not move forward until the Reconstruction Finance Corporation, with support from President Herbert Hoover, agreed to purchase bonds to be repaid later with bridge tolls.
