US President Joe Biden again pledged federal support to rebuild the bridge that collapsed in Baltimore near Washington during a visit to the site on Friday.

A cargo ship rammed into one of the support pillars of the four-lane Francis Scott Key Bridge in Baltimore harbour on March 26, causing it to collapse and killing six workers who were carrying out routine construction at the time.

A third body was located and recovered from the wreckage on Friday, Baltimore Mayor Brandon Scott said.

"While I take solace in knowing this brings us one step closer to closure, my heart continues to be with all the families still waiting anxiously for their loved ones," Scott said in a statement.

"We will continue to do everything in our power to support these families, and provide whatever they need to persevere through this unthinkable tragedy.”

Biden took an aerial tour to survey the wreckage earlier on Friday.

"You know, from the air, I saw the bridge that’s been ripped apart. But here on the ground, I see a community that’s been pulled together," he said during a press conference.

"Our first is our priority to reopen the port. This is one of the nation’s largest shipping hubs. And it’s the top port in America both in importing and exporting of cars and light trucks - the number one."

He said two channels had been cleared to allow for salvage work. A third channel for commercial traffic would open by the end of April while the full channel would open by the end of May, Biden added.

"We’re going to move heaven and earth to rebuild this bridge as rapidly as humanly possible. And we’re going to do so with union labor and American steel."

Those responsible for the collapse would be "held accountable to the fullest extent the law will allow," Biden added.

According to initial findings, there was a problem with the ship's power supply before the accident.
