Francis Scott Key Bridge replacement

The Francis Scott Key Bridge replacement is a project to replace the Francis Scott Key Bridge in greater Baltimore, Maryland, United States. The 1.6-mile (2.6 km) bridge collapsed on March 26, 2024, after a container ship struck one of its piers. The southernmost crossing of the lower Patapsco River, the bridge was part of the Interstate Highway System and a major piece of the region's transport infrastructure: a well-trafficked part of the Baltimore Beltway (Interstate 695 or I-695) linking Dundalk in Baltimore County and the Hawkins Point neighborhood of Baltimore. It crossed the deep-water shipping channel leading to the Port of Baltimore, one of the country's busiest ports.

Six weeks after the collapse, officials at the Maryland Department of Transportation announced plans to replace the bridge by October 2028 at an estimated cost of $1.7 billion to $1.9 billion. The cost will be borne by the federal government under a December 2024 bill signed by President Joe Biden. On November 17, 2025, Maryland officials announced that the projected cost had more than doubled, to an estimated $4.3 billion to $5.2 billion, and that the anticipated opening date had been delayed two years to late 2030.
