BALTIMORE (AP) — Maryland Gov. Wes Moore warned Thursday of a “very long road ahead” to recover from the loss of Baltimore’s Francis Scott Key Bridge as the Biden administration approved $60 million in immediate federal aid after the deadly collapse.

Meanwhile the U.S. Army Corps of Engineers was moving the largest crane on the Eastern Seaboard to help remove the wreckage of the bridge, Moore said, so work to clear the channel and reopen the key shipping route can begin. The machine, which can lift up to 1,000 tons, was expected to arrive Thursday evening, and U.S. Sen. Chris Van Hollen said a second crane with a 400-ton capacity could arrive Saturday.

The state is “deeply grateful” for the federal funds and support, Moore said at an evening news conference.

Moore promised Thursday that “the best minds in the world” were working on plans to clear the debris, move the cargo ship that rammed into the bridge from the channel, recover the bodies of the four remaining workers presumed dead and investigate what went wrong.

“Government is working hand in hand with industry to investigate the area, including the wreck, and remove the ship,” said Moore, a Democrat, who said the quick aid is needed to “lay the foundation for a rapid recovery.” President Joe Biden has pledged the federal government would pay the full cost of rebuilding the bridge.

“This work is not going to take hours. This work is not going to take days. This work is not going to take weeks,” Moore said. “We have a very long road ahead of us.”

Van Hollen said 32 members of the Army Corps of Engineers are surveying the scene of the collapse and 38 Navy contractors are working on the salvage operation.

The devastation left behind after the powerless cargo ship struck a support pillar early Tuesday is extensive. Divers recovered the bodies of two men from a pickup truck in the Patapsco River near the bridge’s middle span Wednesday, but officials said they have to start clearing the wreckage before anyone could reach the bodies of four other missing workers.

State police have said that based on sonar scans, the vehicles appear to be encased in a “superstructure” of concrete and other debris.

National Transportation Safety Board officials boarded the ship, the Dali, to recover information from its electronics and paperwork and to interview the captain and crew members. Investigators shared a preliminary timeline of events before the crash, which federal and state officials have said appeared to be an accident.

“The best minds in the world are coming together to collect the information that we need to move forward with speed and safety in our response to this collapse,” Moore said Thursday.

Of the 21 crew members on the ship, 20 are from India, Randhir Jaiswal, the nation’s foreign ministry spokesperson, told reporters. One was slightly injured and needed stitches, but “all are in good shape and good health,” Jaiswal said.

The victims, who were part of a construction crew fixing potholes on the bridge, were from Mexico, Guatemala, Honduras and El Salvador, Butler said. At least eight people initially went into the water when the ship struck the bridge column, and two of them were rescued Tuesday, officials said.

The crash caused the bridge to break and fall into the water within seconds. Authorities had just enough time to stop vehicle traffic, but didn’t get a chance to alert the construction crew.

During the Baltimore Orioles’ opening day game Thursday, Sgt. Paul Pastorek, Cpl. Jeremy Herbert and Officer Garry Kirts of the Maryland Transportation Authority were honored for their actions in halting bridge traffic and preventing further loss of life.

The three said in a statement that they were “proud to carry out our duties as officers of this state to save the lives that we could.”

The Dali, which is managed by Synergy Marine Group, was headed from Baltimore to Sri Lanka. It is owned by Grace Ocean Private Ltd. and was chartered by Danish shipping giant Maersk.

Synergy extended sympathies to the victims’ families in a statement early Thursday.

“We deeply regret this incident and the problems it has caused for the people of Baltimore and the region’s economy that relies on this vitally important port,” Synergy said, noting that it would continue to cooperate with investigators.

Scott Cowan, president of the International Longshoremen’s Association Local 333, said the union is scrambling to help its roughly 2,400 members whose jobs are at risk of drying up until shipping can resume in the Port of Baltimore.

“If there’s no ships, there’s no work,” he said. “We’re doing everything we can.”

The huge vessel, nearly as long as the Eiffel Tower is tall, was carrying nearly 4,700 shipping containers, 56 of them with hazardous materials inside. Fourteen of those were destroyed, officials said. However, industrial hygienists who evaluated the contents identified them as perfumes and soaps, according to the Key Bridge Joint Information Center.

“There was no immediate threat to the environment,” the center said.

About 21 gallons (80 liters) of oil from a bow thruster on the ship is believed to have caused a sheen in the waterway, Coast Guard Rear Adm. Shannon Gilreath said Thursday.

Booms were placed to prevent any spreading, and state environmental officials were sampling the water.

At the moment there are also cargo containers hanging dangerously off the side of the ship, Gilreath said, adding, “We’re trying to keep our first responders … as safe as possible.”

Divers sent to work beneath the bridge debris and container ship will encounter challenging conditions, including limited visibility and moving currents, according to officials and expert observers.

“Debris can be dangerous, especially when you can’t see what’s right in front of you,” said Donald Gibbons, an instructor with the Eastern Atlantic States Carpenters Technical Centers.

The sudden loss of a highway that carries 30,000 vehicles a day and the port disruption will affect not only thousands of dockworkers and commuters but also U.S. consumers, who are likely to feel the impact of shipping delays.

The governors of New York and New Jersey offered to take on cargo shipments that have been disrupted, to try to minimize supply chain problems.

Transportation Secretary Pete Buttigieg, who met Thursday with supply chain officials, has said the Biden administration was focused on reopening the port and rebuilding the bridge, but he did not put a timeline on those efforts.

From 1960 to 2015, there were 35 major bridge collapses worldwide due to ship or barge collisions, according to the World Association for Waterborne Transport Infrastructure.
