Here's the dozens of bridges that could be at risk of collapse across the US
The National Transportation Safety Board has identified 68 bridges across 19 states that may be at risk of collapse, following 'vulnerability assessments.'
In a new report, the NTSB identified bridges with 'unknown levels' of collapse risk including famous landmarks such as the Golden Gate Bridge in California, and the Brooklyn Bridge in New York.
into the collapse of the Francis Scott Key Bridge in Baltimore in March 2024, which occurred after the Dali containership collided with the structure.
Over the last year 68 bridges have been identified as being built before 1991 and without a 'current vulnerability assessment."
The report urged the bridge owners to calculate whether the probability of a bridge collapse from a vessel collision is above the acceptable risk threshold established by the American Association of State Highway and Transportation Officials.
'If so, we urge them to develop and implement a risk reduction plan that includes input from the interdisciplinary team, identifies short- and long-term strategies to reduce risk, and considers the safety of the vessels and structures in the waterways,' the report stated.
The recommendations have been issued to 30 owners of the different bridges across the country, the bureau announced on Thursday.
Seven bridges were located in California, mostly in the Bay Area – including the iconic Golden Gate Bridge in San Francisco. Thirteen were named in New York state, including the Brooklyn Bridge, Williamsburg Bridge and the Manhattan bridge.
Bridges in need of inspection were also identified in Delaware (3), Florida (2), Georgia (1), Illinois (1), Maryland (3), Massachusetts (4), Michigan (1), New Hampshire (1), New Jersey (2), Ohio (6), Oregon (2), Pennsylvania (4), Rhode island (1), Texas (7), Washington (1) and Wisconsin (1).
A full list can be found in Appendix B of the NTSB report.
The bureau noted that the findings does not suggest that the 68 bridges are certain to collapse, only in need of assessment under AASHTO standards.
On Thursday, federal investigators said that the Maryland Transportation Authority failed to complete a recommended vulnerability assessment that would have shown the Francis Scott Key Bridge was at significant risk of collapse from a ship strike long before its demise.
The NTSB found that the Key Bridge was almost 30 times greater than the acceptable risk threshold for critical or essential bridges.
NTSB Chair Jennifer Homendy said Maryland officials have had decades to assess their bridges. She said they still haven't assessed the Chesapeake Bay Bridge even after last year's collapse.
'There's no excuse,' she said.

NTSB finds a fuel leak and improperly installed parts in the engine of an airliner that caught fire
A fuel leak and several improperly installed parts were found inside the engine of an American Airlines plane that caught fire after the plane landed in Denver in March, according to a new report released Thursday. The National Transportation Safety Board said one part inside the right engine of the Boeing 737-800 was loose and had been installed in an incorrect direction and that fuel was leaking from the fitting of another part that was incorrectly fastened. The preliminary findings don't identify the cause of the fire because the NTSB won't reach that conclusion until after it completes its investigation sometime next year. But former NTSB and FAA investigator Jeff Guzzetti said the problems investigators found in the engine appear to be the source of the fuel that caught fire. 'To me, it looks like improper maintenance in the right engine leading to a fuel leak,' Guzzetti said after reading the NTSB report. Photos and videos posted online showed billowing smoke and passengers standing on the plane's wing after it taxied to a gate at Denver International Airport. Twelve people were taken to the hospital with minor injuries. The plane carried 172 passengers and six crew. The NTSB said gate workers extinguished the fire within a minute even before firefighters arrived and doused lingering hot spots on the plane. Pictures included in the NTSB report show streaks on the outside of the engine from the leaking fuel, and airport video showed a trail of fluid leaking from under the right engine as the airplane taxied into the gate. Guzzetti said he believes those streaks were probably made while the plane was flying. After it landed, he said, the fuel likely pooled inside the engine and caught fire. The American Airlines flight had left Colorado Springs Airport and was bound for Dallas Fort Worth when it diverted to Denver on March 13 after the crew reported high engine vibrations. The plane's right engine caught fire after it arrived at the gate. Passengers started yelling 'fire' and 'smoke' shortly after the plane pulled up to the gate, and flight attendants saw smoke start to fill the cabin, according to the NTSB report. The flight attendants tried calling the flight crew and knocking on the cockpit door, but didn't get an answer. So the report said the flight attendants initiated the evacuation. Passengers were able to use the jetway at the front left door and the escape slide at the right rear door as well as the left over-wing doors to evacuate. But the left rear door wouldn't open, and maintenance personnel discovered afterward that the escape slide jammed in the door. The faulty slide was sent to the manufacturer for further investigation. The country has seen a recent spate of aviation disasters and close calls stoking fears about air travel, though flying remains a very safe mode of transportation.

Horror as plane crashes in mountainous region of North Carolina
A plane has crashed into a mountainous region of North Carolina with three passengers on board. A small aircraft crashed near the Sugar Valley Airport in Mocksville, North Carolina, around 12 pm on Tuesday, the Federal Aviation Administration confirmed. Mocksville is a small town of less than 10,000 people and is about an hour north of Charlotte. The FAA said the aircraft was a Stinson 108 Voyager, which seats four passengers and was produced after World War II until 1950. The National Transportation Safety Board confirmed that they were investigating the crash. A spokesperson for the NTSB told that an investigator was traveling to the scene. 'Once on site, the investigator will begin the process of documenting the scene and examining the aircraft,' the NTSB said. 'The aircraft will then be recovered to a secure facility for further evaluation.' Information on the three passengers wasn't released, and it's unclear what led to the crash. reached out to Davie County officials for more information on the passengers' conditions, but didn't immediately hear back. The incident comes just days after a plane crashed into the Long Island Sound off the coast of Connecticut. There were two people on board the Piper PA-32, a small aircraft that seats six and is typically used for private flights. Branford Fire Chief Thomas Mahoney said the pilot called for assistance before the flight went down. 'The Coast Guard along with Branford Fire Department Marine 5 arrived on location, located the parties in the water [and] brought them safely aboard,' Mahoney added. The aircraft crashed into the water six miles away from Tweed Regional Airport, and emergency responders rescued the two people on board. 'They were wet, cold, and had some cuts on the hands and face,' a Coast Guard spokesperson said. In a third recent incident, two passengers and a dog were killed in a Vans RV-10 aircraft in Los Angeles in May. A Vans RV-10 aircraft is a small four-seat single-engine plane. The aircraft crashed into a home and caused a dramatic fire. The fire department later confirmed that the homeowners evacuated safely.

Confusion on sensor plane's abilities delayed response in Ohio train derailment, report says
A specialized plane equipped with advanced sensors that the government deploys to chemical disasters could have helped authorities avoid needlessly blowing open five rail tank cars and burning their toxic contents after the disastrous 2023 East Palestine train derailment, a new report says. The report released Tuesday found the single-engine Cessna wasn't called into action until the night before the rail cars filled with vinyl chloride were blown open because officials with the Environmental Protection Agency on the ground didn't fully understand the plane's sophisticated capabilities. The report by the EPA's Inspector General said the agency's on-scene coordinator mistakenly thought the so-called ASPECT plane could only measure 20- to 30-degree differences in temperature. In reality, the report noted, the sensors can measure slight temperature differences of less than 1 degree. That information could have helped first responders avoid the key mistake the National Transportation Safety Board identified of blowing open the tank cars filled with the toxic plastic ingredient. The on-scene coordinator's 'limited awareness or use of the full range of ASPECT capabilities could negatively impact emergency response decision-making,' the report said. The towering plume of black smoke The explosion and fire generated a massive plume of black smoke over East Palestine that billowed eastward over the nearby Ohio- Pennsylvania border three days after the derailment. State and local officials in charge of the response feared those tank cars would explode even though the limited temperature information they had showed the cars were starting to cool off. The National Transportation Safety Board had previously faulted the Norfolk Southern railroad for not sharing the opinion of the chemical maker that the vinyl chloride wasn't going to explode with decisionmakers. Norfolk Southern has said OxyVinyls officials offered conflicting information that left the railroad's experts worried about a dangerous chemical reaction. Much of the small town of East Palestine had to be evacuated for days because of the toxic chemical fire. Many residents still complain of lingering health symptoms, fearful of potential long-term health consequences. The EPA has maintained that dangerous levels of chemicals were never found after the evacuation order was lifted five days after the Feb. 3, 2023, derailment. Some have questioned whether the agency did enough to detect the chemicals in the aftermath and doctors are still trying to determine what prolonged exposure to low levels of the chemicals might mean. Recently released records show officials with the Federal Emergency Management Administration have acknowledged residents' fears that cancer clusters could develop years from now in local residents despite the EPA's assurances. Robert Kroutil, the man who wrote the software and helped interpret the data from the plane's advanced radiological and infrared sensors, has said having accurate temperature data from the plane could have helped avoid the vent-and-burn operation. 'The report noted that EPA officials believe that the on-ground monitoring equipment provided superior detection capabilities, which is incorrect,' Kroutil said. "This demonstrates EPA's complete lack of understanding of the ASPECT technology and how it works to protect chemically impacted sites.' EPA updates its policies The East Palestine derailment was the worst rail disaster in a decade. It prompted a national reckoning with rail safety and calls for reform — although proposals for new industry rules stalled in Congress. The railroad's contractors who led the response to the derailment told the NTSB they had difficulty getting accurate temperature readings on the cars because the fire surrounding them made it especially dangerous. Kroutil's concerns prompted the IG investigation. The EPA said in its official response to the report that it has developed a detailed fact sheet and plans to train its emergency responders about the plane's capabilities and when it should be deployed over the next year. But the agency didn't immediately respond Tuesday to questions about the delayed response in East Palestine. Lingering questions about the flights The Government Accountability Project watchdog group that helped Kroutil document his concerns questioned why the Inspector General didn't look into other aspects like Kroutil's concerns that the plane's sensors were intentionally shut off over the creeks around East Palestine and that the final report on the flights was changed to overlook the incomplete data that was generated in just two flights before the plane was sent home. GAP's Senior Environmental Officer Lesley Pacey said 'the investigation's scope was too narrow, failing to address the most serious allegations.' The EPA didn't even call for the sensor plane until two nights after the derailment when officials were already contemplating the vent-and-burn operation. The plane took off from its Texas base within a half hour of getting the call, but it didn't make a pass over the derailment as it flew into the area that night, and then weather conditions kept it from flying during the controversial burn operation the next day. It didn't gather any data until the following day after most of the chemicals had already been distributed by the wind. The Inspector General said the emails and documents it reviewed showed that officials followed existing practices on deploying the plane, but those procedures lacked the clarity needed to help them decide when to deploy the plane.
