Baltimore Key Bridge collapse: Temporary channel opens for boats working on bridge response

Personnel on the ship alerted the Maryland Department of Transportation that they lost control of the vessel, and officials were able to close the bridge before it was struck, "which undoubtedly saved lives," President Joe Biden told reporters.

It appears the crash was a "terrible accident," Biden said.

He said the search and rescue operation is the top priority.

"Ship traffic and the Port of Baltimore has been suspended until further notice. And we'll need to clear that channel before the ship traffic can resume," he said.

"It's my intention that the federal government will pay for the entire cost of reconstruction. ... I expect the Congress to support my effort," Biden said.

"This is going to take some time," the president said, adding, "We're not leaving until this job gets done."

Biden, who noted he’s been over the bridge many times, said he plans to visit Baltimore as soon as possible.

"Our prayers are with everyone involved in this terrible accident and all the families, especially those waiting for news of their loved one right now," the president said. "To the people of Baltimore, I want to say: We're with you. We're going to stay with you, as long as it takes."

Maryland transportation officials reviewed traffic cameras and confirmed there were "no vehicles transiting the bridge at the time of the incident," according to the latest internal Department of Homeland Security briefing obtained by ABC News.

The local pilot who was at the controls is “undergoing post-accident Drug and Alcohol Testing,” the briefing said.

The cargo ship "remains impaled in the bridge," the document said. "Several shipping containers with unknown cargo fell into water. There is hull damage above the water line to the vessel and the ship is maintaining watertight integrity."

A slight sheen of pollution was observed in the water, suggesting there could be some oil or other pollutant “in the vicinity of the ship and pollution booms have been requested,” the memo said.

Six people remain unaccounted for as the desperate search continues at the site of the bridge collapse, Coast Guard officials said at a Tuesday morning news conference.

Two were rescued, including one who was hospitalized and later discharged, officials said. Construction workers were on the bridge working on potholes at the time of the collapse, Maryland Gov. Wes Moore said.

"To hear the words that the Key Bridge has collapsed, it's shocking and heartbreaking," Moore said. "It's not just unprecedented, what we’re seeing today -- it’s heartbreaking."

The collapse appears to be an accident, Moore said.

There’s nothing to suggest ties to terrorism, the FBI added.

The container ship was moving at 8 knots, which is considered fast, officials noted.

A local pilot was at the helm of the ship at the time, Maryland Department of Transportation Secretary Paul Wiedefeld said.

A harbor pilot and assistant onboard the cargo ship reported power issues, multiple alarms on the bridge and loss of propulsion prior to the incident, according to a Coast Guard memo obtained by ABC News. All personnel on the tanker are accounted for with no reported injuries, the memo said.

The Patapsco River channel is fully blocked, with approximately five inbound and seven outbound vessels in the queue for the next 24 hours, according to the memo.

The bridge was up to code, officials said.

The ship departed from the Port of Baltimore at 1 a.m. on Tuesday, embarking on a 27-day journey to Colombo, Sri Lanka. The ship "lost propulsion" as it was leaving the port and warned Maryland officials of a possible collision, according to officials.

The waterway into and out of the port is closed and there is no other route into the port, which is the second busiest port in the Mid-Atlantic.
