The mayor of Baltimore said rescue efforts are underway as footage appeared to show vehicles falling from the bridge.
A major bridge has collapsed in the US city of Baltimore after it was hit by a cargo ship.
Footage shows a large section of the 1.6 mile-long Francis Scott Key Bridge falling into the water following the collision at around 1.30am local time.
Baltimore’s fire service said emergency teams are searching for at least seven people believed to have fallen into the water.

Chief Kevin Cartwright, director of communications for the Baltimore City Fire Department, said the main focus right now is “trying to rescue and recover these people”.
He said it’s too early to know how many people were affected but called the collapse a “developing mass casualty event”.
Mr Cartwright said it appears there are “some cargo or retainers hanging from the bridge,” creating unsafe and unstable conditions, and that emergency responders are operating cautiously as a result.
“This is a dire emergency,” he said.
Vehicles can be seen in the footage falling from the bridge.
