Photos, video show collapse of Baltimore's Francis Scott Key Bridge after cargo ship collision

The Francis Scott Key Bridge in Baltimore, Maryland collapsed Tuesday into the Patapsco River after it was struck by a large cargo ship.

The bridge's collapse has prompted huge emergency response, with the Baltimore City Fire Department describing the collapse as a mass-casualty incident, and rescue crews searching for seven people in the river. Maryland Gov. Wes Moore has declared a state of emergency.

Baltimore Mayor Brendon Scott said on X that he was aware of the incident and was en route to the bridge. "Emergency personnel are on scene, and efforts are underway," he said.

The 1.6 mile, 4-lane bridge named for the author of the "Star-Spangled Banner," was the second-longest continuous-truss bridge span in the United States and third in the world.
