Francis Scott Key Bridge collapse in Baltimore...

according to the post above, after the ships mayday, they were able to halt traffic and that the only persons on bridge was road crew fixing roadway.

I think the fact that it was close to 4am kept this from being a major catastrophe in terms of lives. It could have been so much worse.
I know what they're saying, but it also looked like you could still see a few vehicles passing on the bridge before the ship contacts the support pier with maybe only mere moments to get to safety before there's literally no bridge there anymore.
