BALTIMORE (AP) — A portion of the Francis Scott Key Bridge in Baltimore collapsed after a large boat collided with it early Tuesday morning, and multiple vehicles fell into the water.

Around 1:30 a.m., a large vessel crashed into the bridge, catching on fire before sinking and causing multiple vehicles to fall into the water below, according to a video posted on X, formerly known as Twitter.

“All lanes closed both directions for incident on I-695 Key Bridge. Traffic is being detoured,” the Maryland Transportation Authority posted on X.

Mayor Brandon M. Scott and Baltimore County Executive Johnny Olszewski Jr. posted that emergency personnel were responding and rescue efforts were underway.
