Explosives demolish collapsed bridge in Baltimore, freeing stranded ship and reopening port, with no injuries reported
Crews set off a chain of carefully placed explosives on May 13 to break down the largest remaining span of the collapsed Francis Scott Key Bridge in Baltimore, and with a boom and a splash, the mangled steel trusses came crashing down into the river below.
The explosives flashed orange and let off plumes of black smoke upon detonation. The longest trusses toppled away from the grounded Dali container ship and slid off its bow, sending a wall of water splashing back toward the ship.
It marked a major step in freeing the Dali, which has been stuck among the wreckage since it lost power and crashed into one of the bridge’s support columns shortly after leaving Baltimore on March 26.
The collapse killed six construction workers and halted most maritime traffic through Baltimore’s busy port. The controlled demolition will allow the Dali to be refloated and restore traffic through the port, which will provide relief for thousands of longshoremen, truckers and small business owners who have seen their jobs impacted by the closure.
Officials said the detonation went as planned. They said the next step in the dynamic cleanup process is to assess the few remaining trusses on the Dali’s bow and make sure none of the underwater wreckage is preventing the ship from being refloated and moved.
“It’s a lot like peeling back an onion,” said Lt. Gen. Scott Spellmon of the U.S. Army Corps of Engineers.
Officials expect to refloat the ship within the next few days. Then three or four tugboats will guide it to a nearby terminal at the port. It will likely remain there for a several weeks and undergo temporary repairs before being moved to a shipyard for more substantial repairs.
