okay because I'm seeing some misinfo, here's the story on the Key Bridge collapse

What was the Key Bridge?

The Francis Scott Key Bridge (also called the Key Bridge, the Beltway Bridge, and the Outer Harbor Crossing) was steel-arch continuous-through-truss bridge spanning the Patapsco River south of the Baltimore Harbor. The bridge took 5 years to build and cost an estimated $145 million ($735 million in today's dollars). The full bridge project (including approaches) was 10.9 miles long, but the stretch over the Patapsco was 1.6 miles long and 4 lanes wide, and comprised a length of I-695, the Baltimore Beltway. It traveled between Hawkins Point and Dundalk, and in addition to the I-895 Harbor Tunnel was the primary way for Marylanders to cross from the Eastern Shore to the West. The bridge carried an estimated 11.5 million vehicles per year. There is a lane for ships to pass under the Key Bridge with enough clearance.

Was it structurally sound?

The bridge received its latest inspection in 2022 and received a 6/9 score, which is considered "fair" by federal standards. There was a concern with one of its columns, which was downgraded from a health index of 77.8 to 65.9, but it is not clear yet if this was one of the columns struck by the ship. In 1980 the bridge was struck by a different cargo ship which destroyed a concrete support structure, but the bridge itself was unharmed. There is as of yet no evidence that the bridge collapsed because of poor condition. Experts say the lesson to be learned is about the size and weight of modern cargo ships, and that the bridge was not to blame. Engineers have noted, however, that the bridge's piers lacked protective devices such as fenders.

What was the ship?

The MV Dali is a container ship flying the Singapore flag. It is owned by Grace Ocean Private Ltd. and operated by Synergy Marine Group Ltd. The ship is currently being chartered by Maersk, a Dutch shipping company. It was built in 2015 by Hyundai. The ship is 980 feet long and 157 feet wide. The ship's gross tonnage (its internal volume) is 95,128 tons (190,256,000 pounds). Its deadweight (the weight of cargo it can carry) is 116,851 tons (233,702,000 pounds). The ship was carrying 3,000 containers. The engine is a MAN-B&W 9S90ME putting out 41,480 kilowatts (55,626 horsepower).

Over its lifetime the Dali has been inspected 27 times, and only 2 faults were ever found. On June 27, 2023 the Dali was held in port in Chile due to an issue with the propulsion system. According to an inspector the pressure gauges on the heating system were "unreadable". The fault was fixed before the ship left port.

The Dali is crewed by 22 Indian nationals including 2 maritime pilots.

What happened?

The Dali arrived at the Port of Baltimore on March 23, 2024. At 12:44 AM on March 26, 2024 the Dali left port, beginning its journey to Colombo, Sri Lanka. At 01:26 AM the ship suffered a "complete blackout" and began to drift out of the shipping lane. It is not yet known what caused the electrical failure. The backup generator did not power the propulsion system. At around 01:26 AM the crew of the Dali sent a mayday distress call to the Maryland Department of Transportation (MDOT) informing them of the loss of power and that a collision with the Key Bridge was possible. The anchors were dropped as an emergency measure to attempt to slow or stop the vessel. At the request of one of the pilots traffic flow over the bridge was immediately halted. Black smoke was seen coming from the Dali, which experts believe was the result of the crew managing to restart the power system to regain some maneuvering capability.

At 01:28 AM the Dali, traveling at 8 knots (considered to be a fast speed) collided with a support strut beneath the Key Bridge's metal truss at the southwest end of the bridge. A Baltimore resident said he heard the collision and that it "felt like an earthquake". Emergency teams began receiving 911 calls at 01:30 AM, and the Baltimore Police Department were alerted at 01:35 AM. One of the officers present radioed that he was going to go onto the bridge to alert the construction crew as soon as a second officer arrived, but the bridge collapsed seconds later.

What was the damage?

The Key Bridge has completely collapsed. The metal truss relies on structural tension from the bridge itself to maintain its rigidity. As soon as one of the support columns was destroyed, the rest of the bridge quickly followed.

The damage to the Dali is reported as minimal. The ship was impaled by the bridge's structure above the waterline, but has maintained watertight integrity. The crew has not reported any water contamination from its 1.8 million gallons of marine fuel. 13 containers carrying potentially hazardous material were damaged, and are being inspected by a team of Coast Guard divers. At least 5 vehicles including 3 passenger cars and a cement mixer were detected underwater, but authorities do not believe they were occupied

Who was hurt?

The crew of the Dali reports no casualties, except one crewmember who was hospitalized for minor injuries. There was a crew of 8 construction workers on the Key Bridge filling in potholes. 2 were immediately pulled from the water by rescue crews, with 1 being rushed to emergency care and the other reporting minor injuries and refusing treatment. The hospitalized worker has since been discharged. 1 of those rescued was Mexican. The remaining 6 remain missing. Of those 6, 2 have been identified:

Miguel Luna from El Salvador

Maynor Yassir Suazo Sandoval from Honduras

Of the remaining 4, 2 are Guatemalan nationals. Neither have been identified, but the Guatemalan Foreign Affairs Ministry has stated that they were a 26-year-old from San Luis, Petén, and a 35-year-old from Camotán, Chiquimula. The other 2 are presumed to be Mexican.

Rescue Efforts

The Coast Guard was immediately deployed for search-and-rescue operations. Military Blackhawk helicopters were seen over the river. Rescue efforts were ended at 07:30 PM on March 26, 2024 due to darkness, fog, and cold temperatures. Rear Admiral Shannon Gilreath said "Based on the length of time that we've gone in the search, the extensive search efforts that we put into it, the water temperature -- at this point, we do not believe that we're going to find any of these individuals still alive". Recovery operations resumed at 07:30 AM on March 27, 2024 with all 6 workers presumed dead.

No divers have yet entered the water underneath the bridge. Supervisory Special Agent Brian Hudson of the FBI's Underwater Search and Evidence Response Team said "the debris field is pretty sizable and I know that’s why they’re hesitant to send divers down because some of the debris is still shifting, the heavy weight of the rocks". The FBI has deployed Remotely Operated Vehicles (ROVs) equipped with cameras and SONAR.

Aftermath

At 05:08 AM on March 26, 2024 Transportation Secretary Pete Buttegiege posted on X (formerly Twitter):

"I’ve spoken with Gov. Moore and Mayor Scott to offer USDOT’s support following the vessel strike and collapse of the Francis Scott Key bridge. Rescue efforts remain underway and drivers in the Baltimore area should follow local responder guidance on detours and response."

At 07:30 AM on March 27, 2024 President of the Maryland State Senate Bill Ferguson posted on X (formerly Twitter):

"Over 15,000 in the Balt region rely on daily operations at Port of Baltimore to put food on the table. Today, with Del. @LukeClippinger and colleagues representing Port, we are drafting an emergency bill to provide for income replacement for workers impacted by this travesty."

At around 09:40 AM on March 26, 2024 Maryland Governor Wes Moore and Baltimore Mayor Brandon Scott declared a State of Emergency to take effect at 10:30 AM March 26, 2024, and to last 30 days. Baltimore's Emergency Operations Plan was put into effect.

More than 1,000 personnel from the US Army Corps of Engineers (USACE) have been deployed to assist with clearing the debris and rebuilding efforts. President Joe Biden has pledged that the federal government will pay for the entire reconstruction of the bridge.

Jennifer Homendy, the chair of the National Transportation Safety Board (NTSB) has recovered the Dali's data recorder, and will be inspecting both the Key Bridge and the Dali to determine the cause of the crash and the collapse. She says the investigation could take up to 2 years to complete.

Was it intentional?

According to William DelBagno, head of the FBI's Baltimore field office: "There is no specific or credible information to suggest there are ties to terrorism in this incident".

Secretary of Homeland Security Alejandro Mayorkas said: "There are no indications this was an intentional act".

At least 3 people have been killed in accidents related to ships operated by Synergy in the past 6 years. In 2018 a person on board a Synergy ship in Australia was killed in an accident relating to the vessel's personnel elevator. In 2019 an officer aboard a Synergy vessel in Singapore fell overboard while performing maintenance. In 2023 at least one sailor was killed when a Synergy ship collided with a dredging ship in the Philippines. In the first two cases safety inspectors noted that proper safety procedures had not been adhered to.
