Audio has emerged of a first responder call as officials halted traffic on both sides of the Francis Scott Key Bridge moments before it collapsed.
The cargo ship had issued a mayday call to alert authorities it had lost power before it collided with the Baltimore bridge on Tuesday morning.
Following the call, Maryland Transportation Authority Police Dispatch and Response officials acted swiftly, shutting down the north and south sides of the bridge.

First missing worker named – as rescue mission becomes a recovery operation
One official instructs: “Hold all traffic on the Key Bridge… There’s a ship approaching that just lost their steering so until we get that under control, we’ve got to stop all traffic.”
A minute later, another voice is heard saying: “The whole bridge just fell down. Start, start whoever… everybody. The whole bridge just collapsed.”
The Dali ship ploughed into one of the bridge’s supports and, in an instant, the 1.6-mile-long structure had fallen into the Patapsco River, along with vehicles and workers who were on it at the time.
Six workers missing after the collapse are presumed dead, the executive vice president of Brawner Builders has confirmed.
Officials say the rescue mission for the group has now become a recovery operation.
It comes as Miguel Luna, from El Salvador, was named as one of the six people on the Francis Scott Key Bridge when it collapsed.
Meanwhile, US President Joe Biden has promised that he will visit Baltimore “as soon as possible”, adding that the federal government will cover the “full cost” of rebuilding the bridge.
He told reporters: “Everything so far indicates that this was a terrible accident. At this time we have no other indication, no other reason to believe there’s any intentional act here.
“Personnel on board the ship were able to alert the Maryland Department of Transportation that they had lost control of their vessel.”
Mr Biden added that this meant local authorities were able to close the bridge before it was struck which “undoubtedly saved lives”.
He continued: “Our prayers are with everyone involved in this terrible accident and all the families [affected], especially those waiting for news of their loved one right now. I know every minute in that circumstance feels like a lifetime.”
