3D images released of Baltimore Key Bridge wreckage shows difficult salvage operation ahead

Divers were able to capture the imagery using a tool called CODA Octopus, an underwater sonar imaging tool.

BALTIMORE — The U.S. Army Corps of Engineers released 3D images of the Francis Scott Key Bridge wreckage sitting at the bottom of the Patapsco River on their Facebook Tuesday. The posting marks a week since a cargo ship crashed into the major bridge in Baltimore, resulting in eight workers falling into the cold water -- two of which were saved, two others pronounced dead, and four victims who have yet to be found.

The imagery, which was supplied by the U.S. Navy’s Naval Sea Systems Command (NAVSEA) Supervisor of Salvage and Diving (SUPSALV), shows the wreckage resting at the bottom of the river where the bridge once stood. In the social media post, they stated that the images "show the sheer magnitude of the very difficult and challenging salvage operation ahead."

They were able to get the images using a tool called CODA Octopus, an underwater sonar imaging tool, which is a primary survey tool used by divers. According to the Corps of Engineers, commercial and military divers are working in “virtual darkness” comparing conditions to “driving through a heavy snowfall at night with high-beam headlights on.”

No usable underwater video exists of the wreckage, because as one Navy diver stated, “there’s no need take video of something you can’t even see,” which explains the importance of the technology.
