Baltimore bridge collapse: two bodies recovered during search for victims

Could protective barriers have prevented Baltimore bridge collapse?

The collapse of the Francis Scott Key Bridge in Baltimore, Maryland on Tuesday raised serious questions about what safety or protective mechanisms could have been in place to prevent such a disaster.

It is still unclear what caused a massive 985-foot long cargo vessel to apparently lose control and strike the supportive pylon, a critical part of the structure that keeps the deck of the bridge in place.

Could the bridge have been better protected to safeguard against a large vessel striking a key part of its infrastructure? Experts say the answer is not so simple.

Ron Harichandran, Ph.D., dean of the Tagliatela College of Engineering in Connecticut, told Fox News Digital that protective barriers – if they were there – may not have been enough to stop the Dali, given its sheer size and weight. The Singapore-flagged container has dead weight tonnage, or total tonnage, of nearly 117,000 tons.

"Most of those protections systems that they have directly around the pier would probably not have been able to protect this particular incident because of the size of the cargo ship and the weight," Harichandran said. "It was just too big."

"The only thing that might have worked is if they had sort of an island around the piers and that's not done often," Harichandran added. "It basically involves filling up an area of the river and building an island, so the ship would hit the island and not the pier. That's what you would have to do if you wanted that level of protection, but obviously, that's quite expensive."

"It should really have been done at the time the bridge is built and not retrofitting it," he added.

Jennifer Homendy, the chair of the National Transportation Safety Board, said at a Tuesday press briefing that protective structures would be a part of the investigation into the collapse of the Maryland bridge.

"There’s some questions about the structure of the bridge – protective structure around the bridge or around the piers to make sure there isn’t a collapse," she said, responding to a reporter’s question. "We are aware of what a structure should have. Part of our investigation will be how was this bridge constructed? It will look at the structure itself. Should there be any sort of safety improvements? All of that will be part of our investigation."

The Francis Scott Key Bridge, which was built in 1977, does not appear to have any protective barriers in place, and the pier that was struck was not surrounded by any barrier or buffer-like structures, according to photos and videos from the scene.

There are some small circular-shaped structures in the water, but it is unclear if they are barriers that serve another purpose. A spokesperson for the National Transportation Safety Board (NTSB) did not respond to Fox News Digital's request for comment about whether the Baltimore bridge had a bumper system or protective barriers in place.
