Civil engineer explains why Baltimore bridge so easily collapsed

The Francis Scott Key Bridge's collapse was all but inevitable once a cargo ship rammed into one of the bridge's main supports, according to one expert.

Shocking video shows the moment the bridge appears to snap and fall apart into the Patapsco River. Maryland officials have said there was no structural issues and that the bridge was fully up to code. 

"Part of the problem was this was a massive tanker ship. It was not only carrying a very heavy load, but it was also not just wide, it was tall as well. So it was almost the height of the bridge," said Dr. Ron Harichandran, dean of the Tagliatela College of Engineering at University of New Haven. 

Harichandran, a civil engineer, told Fox News Digital the cargo ship destroyed one of the concrete piers that supported the bridge, sealing its fate.

"If it had not directly hit that and if it had hit between the piers, the bridge may not have completely collapsed because bridges are designed to have some redundancy. But if you hit one of its main support structures, then it's very difficult for it to survive," he explained. 

Modern designs have a sort of "bumper system" around the pier intended to absorb a potential impact, according to Harichandran.

"But again, you know, those can withstand limited amounts of impact, but it's something so massive in terms of cargo vessel. Nothing could be designed to withstand something as large as that."
