In the early hours of Tuesday morning, the global supply chain and US coastal infrastructure collided in the worst possible way. An enormous container ship, the Dali, slammed into a support of the Francis Scott Key bridge in Baltimore, crumpling its central span into the Patapsco River and cutting off the city’s port from the Atlantic Ocean. Eighteen hours later, at approximately 7:30 pm Tuesday evening, rescuers called off the search, with six missing people presumed dead.
With the wreckage yet to be cleared, the Port of Baltimore—a critical shipping hub—has suspended all water traffic, according to the Maryland Port Administration, though trucks are still moving goods in and out of the area. Baltimore is the ninth busiest port in the US for international trade, meaning the effects of the crash will ripple across the regional, US, and even global economy for however long the 47-year-old bridge takes to fix—a timeline, experts say, that’s still unclear.
This will be a special pain for the auto, farm equipment, and construction industries, because Baltimore handles the most “roll on, roll off” ships on the US east coast—an industry term for those designed to handle wheeled cargo. The port has the special equipment to move these products, workers trained in how to use it, and, critically, a location within an overnight driving distance of the densely populated Eastern Seaboard and heavily farmed Midwest.
Almost 850,000 cars and light trucks came through the port last year. So did 1.3 million tons of farm and construction machinery.
Fortunately for the logistics industry, there are some alternative routes both for ships coming into port and trucks crossing the river. Two tunnels traverse the Patapsco, and could take some of the goods and people that once traveled across the Key Bridge, which was also part of Maryland Route 695. Nearby ports, including Norfolk in Virginia, Philadelphia in Pennsylvania, and Savannah in Georgia, should be able to accept many of the goods usually handled by Baltimore’s port.
But the shipping picture will get more complicated the longer the disaster takes to resolve. Ships haul big, heavy goods in large quantities across oceans, albeit relatively slowly—meaning changes to their routes and destinations can add a lot of time to a journey. If a ship is hauling a bunch of different cargos for a bunch of different industries, a holdup along the way causes a lot of people to be screaming for their supplies.
“Everybody right now is saying, ‘We’re just going to reroute, it’s going to be fine,’” says Nada Sanders, an expert in supply chain management at Northeastern University. “If this lasts a while, it’s not going to be fine. It’s going to impact prices.”
Bigger Ships, Same Bridge
The destruction of the bridge also underlines that boats are getting bigger. Trade transport volume across the seas has tripled in the last three decades. At nearly 1,000 feet long, the Dali is emblematic of the ballooning shipping industry.
The growth of boats is down to simple economics: The more goods you can cram on a ship, the more you save on costs. “The amount of cargo has increased tremendously,” says Zal Phiroz, a supply chain analyst at the University of California, San Diego. “This has been impacted to a great degree by Covid, and after Covid as well. The prices of cargo skyrocketed, the prices of containers skyrocketed. Everything just went through the roof.”
