The same way in that a huge ship struck a supporting foundational pier. But different in that the cause was one heck of a storm and spontaneous wind gusts that blew that ship (in Tampa Bay) off course. The ship had emptied its cargo in Tampa and was off somewhere in the Gulf, riding high in the water and with a lot of sail area. But it had power. Another similarity was the bridge decking ending up draped over the bow. I believe the death toll in Tampa was 31-33 people, the majority of which were on a Greyhound bus that took the big dive.
The catastrophic collapse of the Francis Scott Key Bridge in Baltimore was the result of its design that had limited redundancies and is similar to other past bridge collapses. Those catastrophic failures were caused by just one weak element (Tampa, Florida and Minneapolis are examples). Built in 1977, as a continuous through truss bridge, the Francis Scott Key Bridge lacked the redundancies found in more modern designs. The cantilever truss is a better design with protective “barriers” that protect the pier (as in the rebuilt Sunshine Skyway Bridge in Tampa).
Yes, but I think this guy does a fantastic job of explaining what happened here.
