On March 26, 2024, at 01:28 EDT (05:28 UTC), the main spans of the Francis Scott Key Bridge in Baltimore, Maryland, United States collapsed after the container ship Dali struck one of its support pillars.[4][5][6][7][8][excessive citations]

Baltimore City Fire Department officials said that at least seven vehicles fell into the water.[9] Two people were recovered from the river; one declined medical treatment while the other was transported to a hospital in critical condition. At least six people are believed missing.[3]

Background

Main articles: Francis Scott Key Bridge (Baltimore) and MV Dali
The bridge before the collision (seen in 2015), looking upstream. Dali hit the fourth pillar from left.[10]

The Francis Scott Key Bridge, originally the Outer Harbor Crossing, was a steel arch-shaped continuous-through-truss bridge. It opened in 1977 and spanned the Patapsco River, a vital shipping route in the Port of Baltimore,[11] which is one of the busiest in the United States[12] and handled more than 444,000 passengers as well as 52.3 million tons of foreign cargo valued at $80 billion in 2023.[13] It was also part of Interstate 695, a beltway around Baltimore.[11] The bridge was 1.6 miles (2.6 km) long and carried four lanes, two in each direction,[2] carrying an average of more than 11 million vehicles a year, equivalent to around 31,000 vehicles a day.[12]

Dali is a container ship built in 2015 with a length of 980 feet (300 m), a 157-foot (48 m) beam, and a 40-foot (12.2 m) draught.[14] In 2016, it struck its berth in the Port of Antwerp and required repair, although there were no injuries.[15] Registered in Singapore and owned by a Greek shipping company,[16] Dali had previously traveled from Panama to the U.S., arriving in New York on March 19, 2024, before arriving in Baltimore on March 23.[17] As of March 26, it was being chartered by Maersk.[17] The 22 members of the ship's crew on board were Indian,[18] and the ship was being piloted by two local maritime pilots.[10]

The water under the bridge was estimated to be 50 feet (15 m) deep, and the National Oceanic and Atmospheric Administration reported a water temperature of 47 °F (8 °C) at the time of the collapse.[11]

Dali left the Port of Baltimore at 00:44 EDT on March 26, 2024,[19] bound for Colombo, Sri Lanka.[20] Shortly afterwards, the vessel, which had two pilots embarked,[11] reportedly notified the Maryland Department of Transportation that they had lost control of the vessel and a collision with the bridge was possible, citing a loss of propulsion.[21] A mayday was issued, which allowed traffic crossing the bridge to be halted.[4][22][23] The ship's lights were seen to go out and then come on again some moments later, just prior to the collision.[10] The ship also dropped its anchors as part of emergency procedures.[24] At 01:28,[25] the ship struck a support column of the bridge at a speed of 8 knots.[13] The bridge strike and partial collapse were recorded on video.[25]

The bridge broke apart in several places,[26] leaving sections of it protruding from the water and the roadway's approaches cut off where the spans began. Dali caught fire,[11] and a section of the bridge came to rest on the tip of its bow,[2] rendering it stationary.[27] A Baltimore City Fire Department spokesperson said vehicles were on the bridge at the time it collapsed, including one that was the "size of a tractor-trailer".[11] A Maryland Transportation Authority representative on scene told rescuers that at least 20 workers were repairing potholes on the bridge at the time of the collapse.[25] Paul Wiedefeld, the Maryland Secretary of Transportation, said that there were contractors undertaking concrete deck repair on the bridge at the time of the collapse.[28] A resident living near the bridge recalled being awakened by deep rumbling that shook his residence for several seconds following the collapse, which he said "felt like an earthquake."[13]

Emergency teams began receiving 911 calls at 01:30.[2] The Baltimore Police Department was alerted to the collapse at 01:35. Mayor of Baltimore Brandon Scott said that emergency personnel were on scene[29] and that he was en route to the site.[30] Large-scale rescue and recovery efforts were initiated.[25] The U.S. Coast Guard deployed boats and a helicopter as part of rescue efforts.[2] Rescue divers were also dispatched to search for people who fell in the river.[31] A total of 50 divers divided into eight teams were deployed in rescue efforts.[24]

Casualties

At a press conference at 06:30 EDT, Baltimore Fire Chief James Wallace said that at least two people were rescued from the river, one of whom was in "very serious" condition, while another person was said to have walked off with no injuries.[32] At least six people were reported missing.[2][33]

Wallace also said that sonar had detected submerged vehicles in the river, adding that emergency services were also using drones and infrared technology in search efforts.[34] At around 10:55, Wallace confirmed that five vehicles on the river bed had been marked using infrared and side-scan sonar technology.[35]

Synergy Marine Group, which operates Dali, said that the ship's crew, including its two pilots, had been accounted for and did not sustain any injuries, adding that there was no pollution following the incident.[36]

Aftermath

U.S. Secretary of Transportation Pete Buttigieg said that he was in contact with Maryland Governor Wes Moore and Mayor Scott to offer the department's support and advised drivers to follow detour routes.[37] Moore subsequently declared a state of emergency due to the disaster.[2] Wiedefeld ordered the suspension of all shipping to and from the Port of Baltimore[38] until further notice, although land facilities were to remain open to trucking.[11]

Roads leading into Baltimore were closed.[39] Vehicle traffic was able to cross the river via the Fort McHenry and Baltimore Harbor tunnels, although vehicles carrying hazardous loads are not permitted.[10] Advisories were issued to motorists as far away as Virginia warning of traffic delays caused by the bridge collapse.[13] The disaster also blocked maritime access to the Port of Baltimore and trapped several vessels inside the harbor.[10]

At 08:09, the Federal Aviation Administration announced the establishment of a temporary flight restriction around the area of the bridge collapse effective from 08:15, also applying to drones.[40] President Joe Biden was also briefed on the disaster.[11]

Maersk, which chartered the vessel, saw its shares decline by about 2% when trading opened at Nasdaq Copenhagen on March 26.[11] At 11:28, Maersk executives said the company was pausing all service to Baltimore for the foreseeable future.[35]

Investigation

The National Transportation Safety Board announced that an official investigation had been launched and that it was sending a team to the site.[41][42] The Federal Bureau of Investigation was also deployed to the scene, although Wiedefeld said that terrorism was not suspected in the incident.[11]

Structural aspects

Unless protected from collisions, it is impossible for a bridge support to withstand the direct impact of a large ship.[43] The collision of the Dali with the southern main truss-support pillars is believed to have brought down the entire truss span,[citation needed] which saw the pillars being destroyed by the impact.[44] Furthermore, as a continuous truss bridge that relies on its overall structure to maintain integrity, when the south and central spans collapsed, the northern component (the third span) soon followed.[25] Each failure sequence took seconds, and within 30 seconds the entirety of the central span had fallen into the river.[45]
