A timeline of the Francis Scott Key Bridge collapse

Around 1:30 a.m. on Tuesday, Baltimore's Francis Scott Key Bridge collapsed when a cargo ship lost power and crashed into it. Officials were able to prevent cars from driving onto the bridge just before the accident, but eight construction workers remained on the structure and plummeted into the river below. Here's how the events unfolded.
