Baltimore bridge collapse revealed in up-close Coast Guard photos

Bridge collapse: Crane arrives for debris removal

The largest crane on the eastern seaboard has arrived for debris clean-up at the scene of the Key Bridge collapse in Baltimore. FOX's Griff Jenkins joined LiveNOW from FOX's Josh Breslow with a live look at the situation on the ground.

BALTIMORE - As engineers begin to figure out how to clean up the deadly Baltimore bridge collapse, they are getting a closer look at the scene from above and below the water.

The U.S. Coast Guard and Army Corps of Engineers are among the responders at the scene of the Francis Scott Key Bridge collapse, which happened early Tuesday when a cargo barge lost power and rammed a support pillar. Six people, all construction workers on the bridge, were killed.

Thursday, the federal government approved a $60-million "down payment" on efforts to clear the wreckage so the Port of Baltimore can eventually reopen. But that will not be a quick or easy task, as shown by photos released from the scene.

Images show the span’s steel structure twisted and piled atop the stricken ship, which has a huge hole gashed in its bow. Shipping containers and other sections of the bridge are in the Patapsco River and tangled with what remains of the concrete support pillars.

Engineers are still assessing the scene, using aquatic drones and bottom-scanning sonar. It’s not yet clear how long it will take to clear the steel, concrete, and other debris, but experts have already speculated it could take as long as a decade to rebuild the span itself.
