yeah for that bus the difference was seconds. If there hadn't been a snow delay called, there may have been school buses and way more commuters. if it had happened a few hours later, the bridge would have been full. If it had happened on a different day in the afternoon, you could have a crushed after school running club underneath as well.

I have heard several different stories like the one above, people who are usually there or would have been there at that time of day, and didn't on a whim, or because of the snow, or because they were being lazy.

It's truly remarkable no one was killed. The couple in the car that were pulled to safety had some gnarly injuries, but this could have been dozens dead, easily.
