Jakov, in 1987 the Golden Gate Bridge celebrated its 50 year anniversary and was opened for the public to walk across it. About 800,000 people showed up. This was almost 20 times as many as were expected. The graceful curve of the bridge flattened out under the unexpected load (people standing packed like that weigh more than cars do). Unfortunately with half the people coming from one side and half from the other when they met in the middle neither could go any further and it became a huge jam as you can see from the photo.
