  3. Weather, Destroyer of Bridges, HowStuffWorks

    While wind can certainly induce destructive resonant waves, weather as a whole unleashes a host of destructive assaults on the bridges we build. In fact, the relentless work of rain, ice, wind and salt will inevitably bring down any bridge that humans can erect. Bridge designers have learned their craft by studying the failures of the past. Iron has replaced wood, and steel has replaced iron.
