Bay Bridge Anniversary: 90 Years of Connecting the Bay Area

The San Francisco-Oakland Bay Bridge has stood as a critical piece of California infrastructure for nine decades. It opened to traffic on November 12, 1936, marking a major shift in how residents moved between the city and the East Bay. President Franklin D. Roosevelt pressed a telegraph key in Washington, D.C., to give the official green light to that day’s traffic flow. This remote activation symbolized the national importance of the structure, even as local drivers felt the immediate impact.

The bridge’s inauguration occurred during a period of significant economic recovery following the Great Depression. Its completion provided a direct link that reduced travel times and stimulated commerce. The date also coincides with other historical events that shaped the 20th century. In 1927, Leon Trotsky was expelled from the Communist Party, cementing Josef Stalin’s control over the Soviet Union. That same year saw the start of a long era of Stalin’s rule, which would define the geopolitical landscape for decades.

November 12 has been a date of literary and legal milestones as well. American playwright Eugene O’Neill received the Nobel Prize in Literature in 1936, recognizing his contributions to theater. In 1948, a war-crimes tribunal sentenced Japanese general Hideki Tojo to death. Tojo was executed in December 1948, closing a chapter on World War II accountability. The tribunal’s decision reflected the international effort to address the actions of Japanese leaders during the conflict.

The date also marks the end of an era for American immigration. Ellis Island officially closed as an immigration station in 1954. Between 1892 and 1954, more than 12 million immigrants arrived in the United States via the island. Its closure signified a change in immigration patterns and the modernization of border processing. The site remains a symbol of the nation’s history as a destination for newcomers from around the world.

Disasters and accidents have also left their mark on this date. The Bhola cyclone struck East Pakistan in 1970, killing an estimated 300,000 to 500,000 people. It stands as the deadliest tropical cyclone on record. In 2001, American Airlines Flight 587 crashed after takeoff from John F. Kennedy International Airport, killing 260 people on board and five on the ground. The accident prompted extensive safety reviews and changes in aviation protocols to prevent similar incidents.

More recent events include the 2019 flooding in Venice, where water levels reached 6.14 feet above average sea level. The damage was estimated in the hundreds of millions of dollars. In 2021, a Los Angeles judge ended the conservatorship of Britney Spears, a legal battle that had controlled her life and finances for nearly 14 years. In 2024, Jack Teixeira was sentenced to 15 years in prison for leaking classified military documents. He pleaded guilty to willful retention and transmission of national defense information under the Espionage Act.
