Francis Scott Key Bridge collapse in Baltimore...

Mr. Sparkle said
I would be shocked if there was an actual relay from the ship to the local Coast Guard to the road repair team.

I think its much more likely there was no real warning on the bridge except for seeing the damn ship coming at them in the final minute.

There was nothing about a relay from the port to the CG. It was reported that the port notified officials on the ends of the bridge.
