The Francis Scott Key Bridge was a steel arch continuous through truss bridge that spanned the lower Patapsco River and outer Baltimore Harbor / Port. It carried the Baltimore Beltway (Interstate 695 or I-695) between Hawkins Point, an isolated southern neighborhood of Baltimore, and Dundalk in Maryland, United States. The crossing between Baltimore City and Baltimore County also passed through a small portion of Anne Arundel County. The main spans and part of the northeastern approach of the bridge collapsed on March 26, 2024 after the container ship MV Dali struck one of its piers.
