It seems traffic has stopped in the last moments before the hit?

Also looks like it's emergency vehicles in standstill that are falling, i can't discern any moving cars at collapse?

The ship's mayday gave them enough time to stop most, but not all, traffic, according to the MD Governor.

I heard through the grape vine they were able to halt traffic across the bridge at the last minute. Only people actually on it when it fell were construction workers who were filling potholes at the time.
