What Bridge Collapsed in Baltimore?
The Francis Scott Key Bridge, a 1.6-mile steel cantilever bridge carrying Interstate 695 (the Baltimore Beltway) over the Patapsco River, collapsed on March 26, 2024, after being struck by the Dali, a 948-foot container ship, at approximately 1:28 a.m. Six construction workers died; two others were rescued from the water. The ship lost power while departing the Port of Baltimore and struck the bridge's main support column. The collapse severed a critical commuter and freight route and temporarily disrupted port operations, the second-largest on the U.S. East Coast by container volume.
What Happened
The Dali, operated by Synergy Group and registered in Singapore, departed Seagirt Marine Terminal early on March 26. According to the National Transportation Safety Board (NTSB) investigation, the vessel experienced loss of propulsion and steering while in the channel. The pilot aboard requested tugboat assistance, and a mayday call was issued 30 seconds before impact. The ship struck the bridge at Pier 4 (the southern support column), causing the main span to collapse within seconds. Video from nearby traffic cameras, released by news outlets including NBC4 Baltimore and the Baltimore Sun, showed the structure falling into the water.
Six workers from Herndon, Virginia-based demolition contractor Brawner Builders were fatally struck. Two others working in a pickup truck on the bridge jumped into the river and were rescued by U.S. Coast Guard personnel within minutes. The group had been conducting pre-dawn repairs to the bridge's expansion joints, a routine maintenance task.
The collapse caused immediate regional disruption. Interstate 695, one of the region's main bypass routes around Baltimore, became impassable at that location. The Port of Baltimore, which handles 30.7% of U.S. car imports annually (2023 data), suspended container operations for several weeks. Commuters were rerouted through downtown Baltimore or to alternate routes via I-81 north of the city. The Maryland Department of Transportation (MDOT) activated emergency protocols.
Response and Recovery Timeline
The U.S. Coast Guard established a 300-yard safety zone around the wreckage. Within hours, debris removal operations began, focusing first on clearing the shipping channel to restore port access. Underwater salvage teams used cranes and specialized equipment to lift sections of the bridge from the Patapsco River. By May 2024, the main shipping channel was reopened. Full debris removal took several months; MDOT announced in July 2024 that the channel was clear enough for large vessels.
The bridge itself required complete reconstruction. In May 2024, Governor Wes Moore announced a $500 million federal emergency appropriation (part of a broader infrastructure package) to fund rebuilding. MDOT initiated preliminary design work immediately. A temporary travel solution was not built; commuters relied on I-83 (Jones Falls Expressway) northbound into downtown, a significant detour for southern county residents.
The NTSB led the federal investigation, interviewing crew, analyzing ship systems, and reviewing port procedures. Preliminary reports focused on the vessel's power loss and whether pre-departure inspections could have detected the issue. The Port of Baltimore's authority and Maryland State Police also conducted separate inquiries into whether warning systems or bridge protection measures should have existed.
Local News Coverage
The Baltimore Sun (the city's daily newspaper) published detailed coverage beginning with the initial collapse, including crew interviews and victim identification. WBAL-TV (NBC4), WMAR-TV (ABC2), and WJZ-TV (CBS13) provided live coverage throughout the morning and ongoing updates for months. The Sun's investigations later examined port safety, construction worker protections, and the economic impact on regional manufacturing and automotive trade.
Coverage also addressed the human toll: five of the six workers killed were immigrants from Central America. Their families and the construction industry raised questions about workplace safety and emergency communication protocols in pre-dawn work zones.
Related Questions
Will the Francis Scott Key Bridge be rebuilt at the same location? Yes. Maryland officials confirmed the bridge will be reconstructed in place over the Patapsco River. As of late 2024, MDOT was in design phase; construction was expected to take several years, with no official completion date announced.
Did the Port of Baltimore close permanently? No. Container operations resumed in May 2024 after the shipping channel was cleared, though some ships were rerouted to other East Coast ports during the closure. The broader port authority continued operating breakbulk and general cargo terminals.
What ships are allowed in Baltimore Harbor now? The Port of Baltimore resumed standard operations under existing pilot and Coast Guard protocols. No blanket restrictions on vessel size or type were imposed, though the incident prompted discussions about bridge protection infrastructure at U.S. ports.
