Baltimore Key Bridge Collapse Location (26 MAR 2024)

The Francis Scott Key Bridge, known originally as the Outer Harbor Crossing until it was renamed in 1976, while still under construction, or simply as the Key Bridge or Beltway Bridge, was a steel arch continuous through truss bridge spanning the lower Patapsco River and outer Baltimore Harbor / Port carrying Maryland Route 695 in Baltimore, Maryland, United States. The main span of 1,200 feet (366 m) was the third longest span of any continuous truss in the world. It was the second-longest bridge in the Baltimore metropolitan area, after the Chesapeake Bay Bridge.

On March 26, 2024, at around 01:28 EDT (05:28 UTC), part of the through truss bridge collapsed after the Singaporean container ship Dali collided with one of the support pillars. The collapse was declared a "mass casualty incident". An unknown number of vehicles and construction workers were on the bridge at the time of the collision and subsequent collapse
