Sunday marked the 75th anniversary of the opening of San Francisco's Golden Gate Bridge. Before 1937, the city's growth was hampered by a reliance on ferry traffic. The 8,981 ft (2,737 m) suspension bridge changed that, creating a link between San Francisco to Marin County. Its construction was completed under budget, but at the cost of 11 workers' lives. Collected here are images from the building of this iconic bridge, as well as scenes from its 75 years of service and from Sunday's celebration.
