[Time Period] 100 years [Predictions] 
The Brooklyn Bridge and the Golden Gate Bridge finally collapse when their rusted cables snap and can no longer support the weight of the road deck. Within a controlled environment of a preservation vault, materials such as paper and film can last 200 to 300 years, but once exposed to moisture and unregulated temperatures, they will have deteriorated away in half the time. In a humid environment, most books will have been eaten away by mold. Digital media such as CDs and DVDs will take longer to degrade, but ironically, they will not last nearly as long as the information once recorded by primitive cultures on clay tablets.
