Maryland Gov. Wes Moore declared a state of emergency after a cargo ship struck Baltimore's Francis Scott Key Bridge on Tuesday, causing it to collapse.
The collapse sent people and vehicles plunging into the icy, 50-foot-deep waters below. Six people who were on the bridge remain missing.
With the bridge and the surrounding harbor now closed, the catastrophe is also likely to have a major economic impact on Baltimore businesses.
