Addressing a press conference, Rear Admiral Shannon Gilreath said due to the cold water temperatures and harsh sea conditions, it was likely the missing individuals were dead, Xinhua news agency reported.

The US Coast Guard has suspended search and rescue efforts.

The 2.6-km-long Francis Scott Key Bridge, a major bridge that held Interstate 695, collapsed at about 1:30 a.m. local time early Tuesday morning after being hit by a Singapore-flagged large container ship, which experienced a power failure before the collision.

The six individuals who went missing, all road maintenance workers, were reportedly on the bridge repairing potholes when the collapse occurred.

Two other people were rescued from the Patapsco River earlier, with one in critical condition, according to local authorities.

In brief remarks from the White House Tuesday, US President Joe Biden said he wants the federal government to pay for the reconstruction of the bridge. The bridge opened to traffic in 1977 and saw approximately 11.5 million vehicles crossing it each year.

"We're gonna work with our partners in Congress to make sure the state gets the support it needs," President Biden said.
