text: Slide 18 of 48: When the Golden Gate Bridge opened to pedestrians in 1937, the celebrations lasted for a week. The longest and tallest suspension bridge in the world received more than 200,000 foot passengers on its first day. The architecturally stunning bridge was an instant hit and became a symbol of San Francisco. It was one of America’s top-visited attractions, which it remains today. Here the bridge is pictured in the early 1950s. For more amazing constructions, check out the most impressive bridge in every state.
