It’s been over 24 hours since the merchant vessel Dali struck a support pylon holding up the Francis Scott Key Bridge in Baltimore, Maryland early Tuesday morning. The bridge collapsed, killing at least 6 people in the process. Their deaths are tragic losses, the disaster could have been much worse.

The first 12 hours of the disaster were pivotal moments for search and rescue as well as investigators examining what caused this tragic and catastrophic accident. We’ve put together as detailed a recounting of the moments leading up to and during the disaster as possible, using multiple sources and outlets to trace what exactly happened on Tuesday.

12:28 A.M. - The Dali Unmoors From Port

The Dali had just started a 27-day journey from Baltimore to Sri Lanka. The ship had a harbor pilot and their apprentice on board to shepherd the ship out of the harbor. The ship, which is 985 feet long and 158 feet wide, was traveling at eight knots, or a little over 9 miles per hour — standard speed for the harbor.

It is currently unclear why the Dali suffered a complete blackout, though the circumstances around the power loss are under investigation. Current theories include everything from poor maintenance aboard the vessel (the ship had propulsion issues months before the crash) to dirty fuel, according to the Wall Street Journal.

Within just six minutes before impact, cars are still moving across the bridge at this point, according to WBAL.

1:26 A.M. - Lights Come Back On, Smoke Appears

This is likely when the ship’s backup generators came online (that thick plume of smoke being diesel smoke) but for some reason, propulsion was not engaged when the emergency power came on. The power dropped off again moments before impact.

1:27 A.M. - Attempts To Stop, Mayday Call

The harbor pilot had the Dali throw out its port anchor and turn hard left in order to slow the ship. When the ship failed to slow, the captain sent out a mayday and alerted first responders of the danger to the bridge. This message, as well as the quick actions by those on land, likely saved many more lives.

At eight knots, the ship was simply too large and going too fast to stop in time. There were just 90 seconds between mayday and collision for emergency crews to close the bridge to traffic. First responders were unable to move a road crew patching potholes off the bridge in time.

CNN reports rescue work began almost immediately. The first few hours of rescue work was crucial considering the temperature of the water and the height of the bridge collapse. Baltimore Fire Chief James Wallace confirmed the first boats were in the water just over ten minutes following the disaster. The cold water, quick current, rising tide, debris and general darkness hampered efforts to get divers in the water, however.

The only survivors of the road work crew were picked up sometime before 7 a.m. One of the survivors was unharmed while the other was taken to a nearby hospital in serious condition, but was released 12 hours later.

Federal response to the disaster is swift. The FBI is reportedly on scene before 7 as well.

9:30 A.M. - National Transportation Safety Board Launches ‘Go Team’

The collapsed Francis Scott Key Bridge lies on top of the container ship Dali in Baltimore, Maryland, on March 27, 2024. Authorities in Baltimore were set to focus on expanding recovery efforts on March 27 after the cargo ship slammed into the bridge, causing it to collapse and leaving six people presumed dead. All six were members of a construction crew repairing potholes on the bridge when the structure fell into the Patapsco River at around 1:30 am (0530 GMT) on March 26. - Photo: ROBERTO SCHMIDT/AFP (Getty Images)

The NTSB’s “Go Team” brings together various experts in the various issues facing transportation disaster investigators in an area during a transportation crisis. The NTSB will led the investigation and coordinate the various law enforcement agencies in the coming weeks.

Two survivors were pulled from the Patapsco River and six missing people are presumed dead after the Coast Guard called off search and rescue efforts. A work crew was fixing potholes on the bridge, which is used by roughly 30,000 people each day, when the ship struck at around 1:30am on Tuesday morning.

The Governor told assembled reporters that the preliminary investigation was treating the crash as an accident. He also said that the bridge was “up to code” at the time of the incident. The National Bridge Inventory rated the Francis Scott Key Bridge as in “fair” condition as of May 2023, according to the Baltimore Banner:

A “fair condition” rating indicates “that all primary structural elements are sound but may have minor section loss, cracking, spalling or scour,” according to a manual used to interpret scores by the U.S. Department of Transportation’s Federal Highway Administration. On a scale of 0 to 9, with 9 being “excellent” and 0 being “failed condition,” the bridge earned a 5, one step above being deemed in “poor condition” and one below “satisfactory condition.”

At this time, rescuers are still searching for the six missing road crew workers in the wreckage.

It’s unclear when the port, which is the ninth busiest port in the U.S., will reopen. Even less clear is when the 35,000 commuters who used this bridge every day will be able to cut across the river again.

Biden tells reporters that there is no indication of terrorism. The president said the federal government will foot the bill of a new bridge, from CNN:

“It’s my intention that the federal government will pay for the entire cost of reconstructing that bridge,” Biden said from the White House. “I expect the Congress to support my effort — this is going to take some time.”

Responding to a reporter who asked whether the company who owns the container vessel Dali, which collided with the bridge and caused the collapse, should pay for the bridge’s reconstruction, Biden said, “We’re not going to wait for that to happen.”

He continued, “I’ve directed my team to move heaven and earth to reopen the port and rebuild the bridge as soon as humanly possible,” adding that the federal government will work “hand in hand” with the state of Maryland.

The president vows to visit Baltimore as soon as possible.
