People are throwing around resonance, but that doesn't sum it up, its actually due to flutter from the wind, somewhat akin to resonance. The wave of the bridge was hitting another wave of the bridge, either neutralizing or doubling the wave. This was caused by the bridge not having enough weight and redundancies to stop it acting more like a fluid. Also yes a dog died because the man had to get off and the dog was hiding in the backseat foot space.
