Golden Gate Bridge, USA!

Did you know the Golden Gate Bridge once had so many people on it that the famous road deck appeared to lose its normal shape? It happened on May 24, 1987, during the bridge’s 50th-anniversary celebration. Around 300,000 people crowded onto the span, creating an enormous live load unlike anything the bridge normally experienced. With people packed tightly across the roadway, the suspension system responded exactly as a flexible suspension bridge is designed to do. The middle of the span dropped noticeably, making the bridge’s usual upward curve look almost flat. People standing on the bridge could feel it moving beneath them, and the combination of the crowd, wind and swaying reportedly made some visitors feel uneasy. Officials eventually stopped more people from entering because hundreds of thousands were still waiting nearby. The Golden Gate Bridge looked dramatically different that day—but its ability to flex was actually part of what allowed it to handle the extraordinary crowd. Once the people left, the bridge returned to its normal shape. Imagine standing in the middle of that crowd and suddenly realizing the entire bridge is moving beneath your feet.
