Majority of U.S. bridges lack impact protection. After the Key Bridge collapse, will anything change?


In the wake of the collapse of the Francis Scott Key Bridge, which plunged into the Patapsco River in Maryland after the cargo ship Dali slammed into one of its support columns, CBS News has learned a majority of bridges in the U.S. lack any form of impact protection.

Accidents like the one that destroyed the 47-year-old Baltimore bridge aren’t new. A similar collision in 1980 at the Sunshine Skyway Bridge over Tampa Bay killed 35 people. After that incident, codes changed and all bridges built after 1991 were required to have increased protection. 

Structures called fenders and dolphins — which absorb impact, similar to the bumper on a car — are some of the methods used to keep bridges safe.

But the Key Bridge was built in the 1970s, so meeting the current code would require retrofits and upgrades, retired bridge engineer Andy Herrmann said.

“They would either harden the piers so they could take an impact or put a fender, a system of substantial configuration, to deflect that vessel back into the navigable channel,” Herrmann told CBS News. “Or they might do what they did at Sunshine Skyway: Put an island in front of it.”

There are 4,207 bridges in the U.S. that allow ships to pass under them, according to the National Bridge Inventory. Of those, only 36% are described as having functional pier protection — and that included the Key Bridge.

The inventory does not provide specifics about the bridges’ protection or whether they could withstand an impact like Tuesday’s crash in Baltimore, in which a 984-foot, 116,000-ton cargo ship struck a bridge support column. The NTSB said the Dali had been slowing down from about 7 knots (roughly 8 mph) shortly before the impact.

“I was shocked when I saw how that bridge was impacted by the vessel,” said Jim Salmon of the Delaware River and Bay Authority.

Salmon said Delaware is working to avoid a similar tragedy, spending $95 million installing up-to-date protections on the Delaware Memorial Bridge, a dual-span suspension bridge over the Delaware River that connects Delaware and New Jersey and provides a key link between sections of Interstate 95. An application for the upgrades characterized the existing system as “outdated and inadequate to protect the bridge from collisions with the larger and modern vessels.”

Salmon said the improvements, which include new dolphin cells, “protect our tower structures” should a ship lose steering in an incident similar to the Key Bridge allision. 

“It’s what I would call our insurance policy,” Salmon said. “You don’t want to spend $95 million, and have it sitting in the water. You say it’s a lot of money, but like an insurance policy, if something goes wrong, you want to have your insurance there, and that’s our insurance.” 

Once the project is completed, the bridge will be protected from ships even larger and faster than Dali — hauling up to 156,000 tons and moving at 7 knots. 

Structural engineer Matthew Roblez said he was surprised there wasn’t a fender system to protect the Key Bridge. He believes if one had been installed around or in front of the piers, Tuesday’s crash would have been less catastrophic.

Roblez believes there probably wasn’t much that could have been done to completely prevent the Key Bridge collision, but protective systems could have “dissipated the kinetic energy.”

Part of the NTSB investigation into the collision and collapse will examine the structure of the Key Bridge.

NTSB Chair Jennifer Homendy cited data from the Federal Highway Administration which shows of about 615,000 bridges in the United States, 17,468 are “fracture critical.” That means if one piece of the bridge support fails, the whole bridge comes down.

So, the question remains: Four decades after the Tampa bridge collapse, will this latest disaster prompt the federal government to require updated protections for older bridges?

Customers from the East Coast to the Midwest could see costly impact from Baltimore bridge collapse



Customers from the East Coast to the Midwest who were expecting goods shipped in via the Port of Baltimore could see significant cost increases as a result of Tuesday’s collapse of the Francis Scott Key Bridge in Baltimore.

In a statement released after the bridge collapsed early Tuesday, the American Trucking Association estimated some 4,900 trucks per day carrying an annual average of $28 billion worth of goods would have to be re-rerouted — at a cost to shippers and ultimately consumers.

“The Key Bridge and Port of Baltimore are critical components of our nation’s infrastructure and supply chain,” the association said. “Aside from the obvious tragedy, this incident will have significant and long-lasting impacts on the region.”

It noted the greatest impact is likely to be on shipments of hazardous materials, like diesel fuel, which are not allowed to be brought through tunnels.

The closure, the association said, will “add significant cost in time, fuel and delays for trucks traveling through the region, on top of the disruption that a closure of the Port of Baltimore will inflict on our economy.” 

“We urge state and federal government agencies to swiftly target appropriate resources to open the port and replace this bridge as quickly as possible,” the association said.

A spokesperson for the Council on Safe Transportation of Hazardous Articles said it was declining to comment on the situation.

The collapse is being blamed on a cargo ship that lost power and slammed into a bridge pylon early Tuesday. Maryland Gov. Wes Moore has declared a state of emergency, and President Joe Biden said he would direct federal resources to address the situation.

Baltimore is the largest entry point in the U.S. for large agriculture and construction equipment like tractors, farming combines, fork lifts, bulldozers and heavy-duty trucks that are bound for the Midwest, according to DAT Freight and Analytics, a freight-exchange service.

Any disruption to agriculture and construction equipment shipments would come at a particularly bad time as Midwest farmers have begun to plant this year’s crops, while construction picks up in colder climates as the ground begins to thaw, said Dean Croke, principal analyst with DAT.

“I think it has a huge economic impact on the farming industry,” said Croke. “This is peak planting season in the Midwest and peak machinery import season. March is the biggest month for machinery shipments into the U.S. via Baltimore.”

Companies may have to reroute their shipments to nearby ports, like those in Georgia or Florida, he said. That will mean higher freight shipping costs as trucks have to travel further and may have to wait longer to pick up their loads if those ports become congested, said Croke.

The complete collapse of the bridge means it could take up to a year for normal logistics patterns to return, said Tinglong Dai, a professor at the Johns Hopkins Carey Business School.

“It’s very difficult to estimate the [shipping] cost impact, but it’s fair to say it’s going to be costlier to transport autos and trucks to and from the U.S. in the short term because of the oversize impact on the port of Baltimore,” he said.

Baltimore is also the No. 1 automobile port in the U.S. Other Eastern Seaboard ports are expected to be able to shoulder some Baltimore-bound auto shipments, said Emily Stausbøll, market analyst with the shipping group Xeneta, which could limit the impact on global shipping rates.

“However, there is only so much port capacity available and this will leave supply chains vulnerable to any further pressure,” Stausbøll wrote in a note to clients.

In an interview with CNBC, Richard Meade, the editor-in-chief of Lloyd’s list, a shipping journal, said: “It will be expensive but it is not a supply chain story like the EverGiven (which was stuck in the Suez Canal) because ocean carriers will find alternative routes,” said Meade. “Logistically, ocean carriers and trucking have the ability to be pretty adapt and agile.”

A spokesperson for the port of Norfolk, Virginia — another major terminal along the East Coast — said its team was already working with ocean carriers whose vessels were bound for Baltimore to see about rerouting south.

“The Port of Virginia has a significant amount of experience in handling surges of import and export cargo and is ready to provide whatever assistance we can to the team at the Port of Baltimore,” the spokesperson said.

Some automakers said there may not be a major impact.

A General Motors spokesperson said it expected the incident to have a minimal affect on its operations, and that it was working to re-reroute vehicle shipments to other ports.

A BMW spokesperson said that its receiving terminal is located at the Baltimore harbor’s entrance in front of the bridge and was still accessible.

“We do not expect this morning’s tragedy in Baltimore to have any immediate impact on our business, other than short term traffic delays,” the BMW spokesperson said in an email.

Other companies with significant operations in the port area said the impact from the collapse would be minimal. In a statement, a Home Depot representative said its distribution centers in the area remained open and operating.

Amazon, which also has a major distribution center at the port, declined to specify what, if any, effects there might be.

“We’re assessing the immediate and future impacts to our employees and delivery partners, as well as the surrounding community and will make any adjustments to our operations that are needed,” an Amazon rep said in an emailed statement.
