The Automobile Age
Postwar suburbanization in Marin County sent traffic surging far beyond original projections, transforming the bridge from an engineering marvel into a daily commuter lifeline. In 1968, the original six-lane configuration was reconfigured with a movable median barrier to accommodate tidal traffic flows. The bridge became both an icon of California car culture and an early symbol of the tensions between growth and livability.
On December 1, 1951, the Golden Gate Bridge closed to all traffic for the first time in its history when gusts reached 69 mph, forcing engineers to confront the limits of its original design.
Alfred Hitchcock filmed his masterpiece beneath the Golden Gate, forever linking the bridge to cinematic obsession and dread.
Marin County pulled out of BART, killing the plan to run trains across the Golden Gate Bridge and shaping Bay Area transit for generations.
Thirty-three years after the bridge killed ferry service, crushing traffic congestion forced the Golden Gate corridor to bring the boats back.
