The cargo ship that struck the Francis Scott Key Bridge in March was refloated and moved from the site of the crash early Monday morning.

Why it matters: Nearly two months after the deadly collision, moving the Dali marks a critical step towards the full reopening of Port of Baltimore.

The catastrophic bridge collapse killed six construction workers and snarled shipping and traffic in one of the U.S.' busiest ports.

Driving the news: Crews began hauling the ship away at about 7am ET towards a local marine terminal, the Key Bridge Response Unified Command said in a press release Monday.

"The Unified Command's operational priorities are ensuring the safety of the public and first responders, safely restoring the marine transportation system and commerce, protecting the environment, and supporting the investigation," the press release added.

The Dali's removal came after crews set off a series of controlled explosions earlier this month to free the ship from a portion of the bridge wreckage that was pinning it down.
