What Happened to Francis Scott Key Bridge?

The Francis Scott Key Bridge, a vital part of Interstate 695 and the Baltimore Beltway, tragically collapsed into the Patapsco River on March 26, 2024, at approximately 1:28 a.m. EDT. The catastrophic event occurred when the Singapore-flagged container ship MV Dali, outbound from the Port of Baltimore, experienced a complete power blackout and lost propulsion, subsequently striking one of the bridge's main support piers. Six construction workers, who were filling potholes on the bridge at the time, were killed, and two others were rescued.

Investigations by the National Transportation Safety Board (NTSB) revealed that the Dali suffered multiple electrical issues, including a loose wire in its electrical system, which led to the power outages. These failures, compounded by the bridge's older design which lacked modern pier protection systems capable of withstanding a collision from a vessel of the Dali's size, were critical factors in the collapse. The ship's crew issued a Mayday call moments before impact, allowing authorities to stop traffic onto the bridge and preventing further casualties.

The immediate consequences were severe. The collapse blocked the main shipping channel to the Port of Baltimore, one of the busiest on the U.S. East Coast, for approximately eleven weeks. This closure had a significant economic impact, estimated at $15 million per day, affecting over 8,000 jobs directly and indirectly, and disrupting national and international supply chains. The port is a major handler of automobiles, light trucks, and other cargo, and its disruption necessitated costly rerouting of goods.

In the aftermath, salvage operations quickly commenced to clear debris and reopen the channel. By December 2024, full federal funding for the bridge's replacement was secured through a bill signed by President Joe Biden. Initial cost estimates for the rebuild ranged from $1.7 billion to $1.9 billion with a projected completion by October 2028. However, by November 2025, Maryland officials revised these estimates significantly, increasing the projected cost to $4.3 billion to $5.2 billion and delaying the anticipated opening to late 2030, citing rising material costs, tougher federal safety rules, and the need for a more robust vessel collision protection system.

As of May 12, 2026, the rebuild project continues to face challenges. Maryland officials announced in April 2026 that they would part ways with Kiewit Infrastructure Co., the initial contractor for Phase 2 design and pre-construction, due to high-cost proposals that some lawmakers suggested could have pushed the total project cost to $8-9 billion. The state is now seeking new construction partners for the next phase, though Kiewit is expected to complete its Phase 1 contractual obligations, including foundation pile driving and temporary trestle construction, through at least the end of 2026. Demolition of existing land structures and the test pile program were completed in February 2026, with permanent pile installation and temporary trestle construction ongoing.

In a significant development on May 12, 2026, the Justice Department unsealed an indictment, filing criminal charges against Synergy Marine Group, the Singapore-based operator of the MV Dali, and Radhakrishnan Karthik Nair, a technical superintendent. The charges include conspiracy to defraud the United States, failing to inform the U.S. Coast Guard of a known hazardous condition, false statements, and obstructing an agency proceeding. Prosecutors allege the company fostered unsafe conditions and improperly used a 'flushing pump' for fuel supply, contributing to the blackouts. This marks the first criminal charges in connection with the deadly collapse, underscoring the ongoing legal and investigative ramifications of the disaster.
