Slow-moving traffic

Slow-moving traffic People celebrate as they walk across the Golden Gate Bridge on May 24, 1987. The bridge celebrated its 50th anniversary with a “Bridgewalk 87,” as homage to Pedestrian Day when the bridge opened in 1937. About 300,000 people crowded onto the roadway, arriving from both ends of the bridge, and created gridlock at the center. The weight of the crowds caused the bridge’s arch to flatten out and disappear. (Paul Sakuma / AP) People celebrate as they walk across the Golden Gate Bridge on May 24, 1987.
